Radiologists will now be able to identify more patients with undiagnosed fractures and provide better care for patients who may be vulnerable.. That means the pixels are there and the compression fractures are already captured in the data theyre just not reported. This also makes it very simple for Eyal and his team to roll out new versions of the model. Theyre already on their way to their seventh FDA-approved diagnostic solution, with more coming soon. For clinical solutions, thats not usually realistic or responsible. All rights reserved. Even then, you still cant be sure that the doctor would benefit from using your diagnostic model. Its Imaging Analytics Platform allows healthcare institutions to identify patients at risk of disease and offer improved preventative treatment pathways to improve patient care. They also adhere to and are tested on three different ISO standards, as well as SOC 2 Type 2 internal controls reports issued by third-party auditors. So if there are any mistakes in your data like a wrong diagnosis then the model will also learn those mistakes. Osteoporotic fractures affect nearly 50 percent of men and 25 percent of women during their lifetimes, resulting in 2 million broken bones annually and an estimated $52 billion cost to the U.S. healthcare system. There are a wide variety of workstation providers and software, as well as different kinds of environments (e.g., web-based or Windows based). If the machine learning model is going to be of any use to the doctor, it needs to be able to differentiate among radiology images of patients with symptoms not between healthy and unhealthy people. Separately, Nanox has also agreed to acquire US-based radiologist-run and operated full-service subspecialty radiology and teleradiology company USARAD and its related entity Medical Diagnostics Web (MDW) for $30m. Nanox said the acquisition of Zebra Medical Vision would help achieve both companies shared goal of forming the next generation of AI-enabled hardware and software devices to set a new standard in the medical devices sector. As Eyal discovered, this flexibility is absolutely essential. So they went looking for the reasons behind this reality. The company has received honours and awards, including being named a Top 5 global AI company by Fast Company. Plus Zebra-Med calculates the predictions in advance, so when a physician clicks on an image, they can see the result immediately. Unfortunately, the buildup of calcifications in coronary arteries is often only diagnosed after a heart attack or similar cardiac event. Its safe to assume that doctors, like anybody else, want new solutions to make their work easier not more complicated. Zebra Medical Vision has always operated to expand the use of AI in medical imaging to improve health outcomes for patients worldwide, said Zohar Elhanani, CEO of Zebra Medical Vision. The problem with this approach: This particular CT scan protocol is something you would only run on a patient who is already known to have a risk of a heart attack. Nanox said it agreed to acquire AI developer Zebra Medical Vision in an all-stock transaction valued at up to $200 million $100 million upfront and another $100 million tied to specific milestones, all in stock. In university studies, the problem youre working on is often fixed. Zebra-Med currently provides seven FDA-cleared and 10 CE-marked AI solutions for medical imaging. All Rights Reserved. If this happens in the arteries that supply blood to the heart muscle, then it can limit or stop the supply of oxygen to the heart and cause a heart attack. Lets say you build a system that can take a radiology image and then correctly judge whether the image shows signs of lung cancer or indicates a healthy patient. ZebraMedicalVision has 7 FDA approved solutions heres how they did it. They also built tools to track all of these experiments and then compare the results. With all this infrastructure and this team in place, Zebra Medical Vision can move at a dazzling pace. Many companies talk about feedback loops where the model improves via user feedback. Under the deal, Zebra-Med will receive up to $100m as an upfront payment, as well as an additional $100m based on the achievement of certain milestones. Now hospitals that run screening programs on patients who are at risk of osteoporosis can run this model in the background and are automatically alerted to patients who likely have a fracture. But if we want to connect research with the clinic in a way that satisfies regulatory requirements were still missing something. We use them to give you the best experience. For their studies, Zebra Medical Vision had to coordinate support from up to 60 different expert annotators worldwide all working on the same clinical mission. At first sight this might seem very useful. So lets say youve managed to build a model that accurately represents the population, seamlessly integrates into diagnostic workstations, and fits the doctors workflow. But as Eyal said, You need to be extremely stupid in positive way.. In the end, 75% of all VCFs go undiagnosed or unreported. But academic research leaves this issue unresolved. But this isnt the only hurdle to making a useful model for everyday hospital diagnosis. In this case, it doesnt matter how much more quickly the AI can make a single assessment if the doctor has to spend extra time checking and refuting most of the cases the AI flagged. In the end, even if it took a bit longer, it would be an extremely meaningful challenge, and the impact and value of the project would be undeniable. Zebra Medical Vision uses artificial intelligence and deep learning to create and provide next generation products and services to the healthcare industry. Our plan is to double down on Zebra-Meds AI and cloud platform effort, strengthen the industry-leading team even further, and solidify Zebra-Meds leadership position in the radiology space. For example, 50% of patients who fracture a hip die of complications in the next 10 years. It has even outperformed other solutions that only work on gated CT scans. But Eyal and the band found that they very often make discoveries along the way. Heres why. Then theres also the immense burden of rehabilitation. In fact, this isnt a question that comes up in a hospital. Nanox also announced that it has entered into a binding letter of intent to acquire USARAD and its related company, Medical Diagnostics Web, or MDW. Radiology images in many different modalities (X-Ray, CT, MRI, Mammography, PET, and Nuclear Medicine); Clinical outcomes (meaning how patients fared after discharge, possibly years later). But most people in high-risk groups already have a scan somewhere on file. The false-positive rate. Expanding access to medical imaging via the widespread deployment of the Nanox.ARC solves one of the obstacles to achieving true population health management, said Ran Poliakine, Chairman and Chief Executive Officer of Nanox. Ran Poliakine added: The Nanox.ARC, together with Zebra-Med, would move us toward our vision of deploying our systems. But does this scenario (lung cancer vs. healthy patient) really represent the problem a doctor would face? Due to this change if you are seeing this message for the first time please make sure you reset your password using the Forgot your password Link. According to the company, the newly discovered findings can then initiate a further medical assessment to establish individual preventative care pathways for patients. This strategic move represents an end-to-end, globally-connected medical imaging solution.. With this CPT code in place, providers using the tool will be able to submit for reimbursement, potentially increasing its use. This system automatically alerts them if a patient is high risk even though they took the scan for another reason and may never have looked at the heart. In practice, the model has to fit seamlessly into the existing workflow.

It also offers a 3D modeling solution for x-ray images used for orthopaedic surgery pre-operative planning. According to existing data, Zebra Medicals VCF solution can increase detection rates, bringing needed treatment to more patients without addition imaging or radiation. But their nave optimism saved them. Everyone told them: There will never be anything like machine vision in radiology. Lets say there are 6 cancer diagnoses for every 1,000 mammographies, and youve trained a machine learning model that can assess the images in real-time. The deal consists of $21m of Nanox shares and $9m in cash. The latest development regarding the CPT code approval by the AMA is an industry milestone in the effort to boost the adoption of AI in imaging for VCFs and other under-diagnosed chronic conditions for which can help reveal and drive care, said Zohar Elhanani, Zebra Medical Vision chief executive officer. AI for Diagnostics, Drug Development, Treatment Personalisation and Gene Editing. This helps the clinicians who really care, who deal with osteoporosis prevention and treatment programs, to identify patients with VCFs. Nanox Acquires Medical Imaging Company Zebra Medical Vision for $200 Million. So far, this is just a proof-of-concept youve demonstrated that an algorithm can process radiology images and differentiate between two clearly described groups of patients. This mindset pushed them on through myriad challenges. If the doctor doesnt look at a scan because the system says the patient is healthy when they arent, then the patient might miss their chance to get treated. The more practical approach: Zebra Medical Vision realized that patients get CT scans for many other diseases. Zebra-Med currently provides seven FDA-cleared and 10 CE-marked AI solutions for medical imaging, including a 3D modeling solution for x-ray images used for orthopaedic surgery pre-operative planning, The deal will enable both firms to create advanced AI-enabled hardware and software devices. 2022 MJH Life Sciences and Diagnostic Imaging. But this wasnt easy. Product definition and system requirements. They are all necessary. Zebra-Meds algorithms highlight early, previously undetected signs of common chronic diseases using patient imaging data already available to the healthcare system. For more coverage based on industry expert insights and research, subscribe to the Diagnostic Imaging e-Newsletterhere. Code is for vertebral compression fracture detection with CT scans. How often does the model think a patient is healthy when in fact they are not? One reason is Zebra Medical Visions technological backbone, which allows them to work fast and to easily modify and rerun experiments without starting from scratch. Doctors and clinicians needed: The first issue Eyal and his team discovered was that most academic research relied on small datasets. Then doctors can confirm these cases with a manual check. Now we covered partnerships, data, integration, and the technical backbone. Once Eyal and his team had both the data and a means of getting solutions into clinicians hands, they had to build a highway on top of this bridge: the technological backbone that would make everything else possible. A diagnostic model is considered a medical device, and any change has to go through the process of regulatory approval. Youll inspect it diligently, try to understand why the AI system might have deemed it problematic, and spend a lot of time deliberating before you conclude: No, the AI made a mistake. This kind of error is obviously very dangerous. Even though the problem isnt sexy and doesnt receive much attention, the benefits of diagnosing VCFs and consequently osteoporosis are immense for the patients. We have recently upgraded our technology platform. Its more likely that a patient comes to you because they have some symptoms already, and you need to diagnose the cause: ground-glass opacity, pulmonary embolism, COPD, emphysema, and lung cancer might all present similar symptoms. Siemens' ARTIS Icono Ceiling Angiography System Wins FDA Clearance, Study Suggests AI Enhances Non-Contrast CT Detection of Large Vessel Occlusion, FDA to Allow Bracco to Import Iomeron Iodinated Contrast Media as Shortage Drags On. Instead they focused on developing data partnerships with over 30 hospitals in Israel, the US, and India. This is exactly the situation Eyal faced in 2014, when Zebra Medical Vision was born: lots of breakthrough research, an obvious need for AI support in diagnostics, plenty of talent, but almost no solutions in day-to-day clinical use. AI1 is the company's commitment to making artificial intelligence (AI)-enabled healthcare solutions affordable globally, including its current and future algorithms available for a low flat price per scan. This required a huge investment in security, as well as making sure everything is logged and documented. And weve shown that simply having an automated diagnostic model doesn't necessarily mean youre saving a doctor time seamless integration and a manageable false-positive rate are essential. The digital X-ray company Nanox agreed to acquire Zebra Medical Vision, which develops an AI-powered medical imaging platform that spots breast cancer, brain bleeds, and more in standard X-ray images. For example, you might develop a very accurate machine learning model that only performs well when the image is taken with specific machine settings settings a doctor wouldnt normally use in a routine exam. But these elements are still not sufficient to solve a machine learning diagnostics problem or what Eyal calls a clinical mission. All rights reserved. Everything connected to the development and use of a diagnostic model needs to be traceable, including: Zebra Medical Vision built a global quality management system which provides this information to the FDA on an ongoing basis, gaining trust through transparency. But this doesnt work for machine learning: there are so many ways to slice the data and build a model, you would never reach the end. This strategic move represents an end-to-end, globally-connected medical imaging solution.. The acquisition of Zebra-Med will allow Nanox to support the firms medical device strategy by integrating its AI-based solutions into its imaging equipment. While many studies might simply compare doctors and machines diagnostic performance using one type of data, Zebra Medical Vision had to go further. Eyal and his team found an approach where they could take these much more frequent scans and still achieve a similar accuracy - in predicting risk for heart disease - to the model that the researchers build for the targeted scans. And therefore, this would not help all the other patients who are at risk but have no symptoms yet. But for many years, AI-supported diagnostic solutions were not actually being used in hospitals. Both deals are subject to satisfaction of the conditions to closing in the definitive agreements, regulatory approvals, and other customary conditions. Zebra Medical Vision didnt build a new software tool for doctors to add to their workflow. Today this is one of Zebra Medical Visions leading solutions, and its proven to be effective on a large part of the population. This means: A clinically useful model should not require the clinician to perform any additional steps. Of course, the team still appreciates getting feedback from doctors so they can understand how the model is performing and put that learning to use in future iterations. For real-world diagnostic solutions, representative data is absolutely crucial. Considering how few patients have symptoms before a heart attack, it would be more helpful to find a way to diagnose a much larger group of patients. Cellular waste products, proteins, and calcium stick to blood vessel walls and combine with fat to form plaque. 2022 MJH Life Sciences and Diagnostic Imaging. Machine Learning models learn from the dataset. Vertebral compression fractures (VCFs) a condition in which part of a vertebra bone in the spine collapses are often simply ignored by radiologists. But vertebral compression fractures a reliable symptom of osteoporosis are often missed during routine exams. Essentially this is a segmentation problem: you segment the white clouds of calcification in the coronary arteries. Nanox says that these two agreements intended to create a globally connected, end-to-end radiology solution. Zebra Medical Vision announced July 7 it has received approval of its CPT application for using artificial intelligence (AI) with CT scans to detect vertebral compression fractures (VCF) from the American Medical Association (AMA). Still, Zebra Medical officials said, 75 percent of these fractures go undetected. This means doctors now have an early-warning system for heart disease running in the background. This means hospitals dont need to do anything to receive updates. Israel-based Nanox has agreed to acquire deep-learning medical imaging analytics company Zebra Medical Vision in a deal valued at around $200m. This error is much less problematic the doctor will cross-check the scan because the system flagged it, and will discover it was a false alarm. Someone needs to fill the gap. Zebra Medical Vision very quickly learned that data scientists cant build a useful medical device all on their own. They found that research alone couldnt address some of the critical challenges which needed to be solved before AI diagnostics could be applied in clinical contexts. But it wouldnt be useful in a hospital. So Eyal [and the team] needed to build a platform to allow researchers to test not one, but thousands of experiments at the same time. This is the first AI CPT code specific to radiology. Founded in 2014, Zebra Medical Vision has 7 FDA-approved and 10 CE-marked AI solutions for medical imaging, with a recently introduced 3D modeling solution for x-ray images used for orthopedic surgery pre-operative planning. Many research studies have shown that machine learning models can perform as well as trained doctors on a range of tasks especially in radiology and can even find patterns a human doctor would miss. If you continue using our website, we'll assume that you are happy to receive all cookies on this website. Eyal and his co-founder thought they could solve this problem, and fast. (Credit: Business Wire). How often does the system flag a scan when the patient is in fact healthy? USARAD operates a network of 300 radiologists. In addition, the transaction will enable both firms to create the next generation of AI-enabled hardware and software devices. The deal will help the company to expand its mission of diagnosing populations at scale with its AI-based solutions. Solving the problem in this way is certainly a valuable research result, but its still far from a workable diagnostic model for clinical practice, because it requires a non-standard workflow. So the first challenge is getting a large, diverse dataset that looks exactly like what youd expect to see in a hospital. The band is very well suited to adjust to these changes. But this is just one of the hurdles of working in a regulated environment. They dubbed this role the Clinical Information Manager - and this person usally has a PhD in biomedical engineering or clinical research. Each clinical mission also needs a project manager, a research engineer, and an operations engineer. Enjoy your vacation, go back to Israel, and find something else to do.. Zebra-Med built a smart infrastructure that allows for flexibility while minimizing double work. This seamless integration is essential not only because asking doctors to change their workflow is unrealistic, but because the whole point of using AI is to save time, not to create additional work. Youre nice Israeli guys. That's a fantasy. Get our leading market intelligence Your submission has been received! But overall, the false positive rate still determines whether the system saves the doctor time. The false-negative rate. Can deep learning extract new insights from basic H&E stains? These so-called untargeted or ungated scans can include many organs, and also the heart. Plus a lot of the software is quite old. 2022 by Mercom Capital Group, LLC. Not only were they small, but they also didnt represent the variety of patient cases clinicians see in hospitals on a day-to-day basis. In the past, a researcher might take the time to design the perfect experiment, implement it, and then assess whether their approach solves the problem. But in medical diagnostics, innovation simply didnt translate into practice. A total of 136 digital health companies were acquired in the first half of 2021, Total Corporate Funding for Solar Sector Totaled $12 Billion in 1H 2022, Mirova Acquires SunFunder to Expand Clean Energy Investments, Zerigo Health Raises $43 Million for Connected Skin Therapy Device, Oak Street Health Acquires Telehealth Company RubiconMD for $130 Million, Workit Health Raises $118 Million for Addiction Care Platform, Modern Age Raises $27 Million for Digital Aging Wellness Platform, Bardavon Health Innovations Raises $90 Million in Funding, Insurights Raises $22 Million in Seed Funding, SPR Therapeutics Raises $37 Million for Wearable Neurostimulation Device, GoCheck Raises $10 Million for Vision Screening App, Top Doctors Raises $13 Million for Healthcare Booking Platform, Insiteflow Raises $2.3 Million for EHR Workflow Interoperability Platform. Half of all cardiovascular-related deaths are due to coronary artery disease. Having a band that works closely together means everything can be much more dynamic. With more than 300 US-certified radiologists in its organisation, USARAD will offer Nanox immediate access to trained radiologists. As Eyal says, Sometimes we look at the problems that are meaningful and not sexy. This is exactly the kind of opportunity you find when you look at large datasets with an exploratory mindset a data scientists mindset. Upon completing the acquisition, Zebra-Med will be a wholly-owned subsidiary under the Nanox brand. On the other hand, all the heavy lifting and prediction happens in the cloud. Early diagnosis and treatment for osteoporosis is essential. Nevertheless, Zebra-Med has to integrate with each of them. Our plan is to double down on Zebra-Meds AI and cloud platform effort, strengthen the industry-leading team even further, and solidify Zebra-Meds leadership position in the radiology space. Zebra Medical Visions two systems for research (model training and testing) and clinical use are entirely separate. Imagine you see that a scan is flagged. Instead they partnered with diagnostic workstations and integrated their predictions directly into the software tools the doctors were already familiar with. The doctor now sees the AI models assessments next to all of their scans and can prioritize the cases that have been flagged. Models trained on datasets that represent the population; Seamless integration into clinical workflows; A technology platform to connect research and hospitals. Thats why, for the first two years, Zebra Medical Vision hardly did any machine learning at all. It should only require the exact data in the exact format thats already produced in the hospitals normal diagnostic workflow.
