In 2021 the application of AI enabled advances in many areas of healthcare. We made significant progress in AI for drug discovery, medical imaging, diagnostics, pathology, and clinical trials. Important peer reviewed papers were published and dozens of partnerships were formed. Big Pharma companies and major tech companies became very active in the space. Record amounts of funding were raised, and a few companies even started human clinical trials. Microsoft and NVIDIA launched two of the world’s most powerful supercomputers and Microsoft announced Azure OpenAI Service. In 2022 I expect several technologies to converge across the healthcare spectrum.
This is the first in a series of progress reports I’m writing on the sector that will be supplemented by industry performance data and metrics compiled in partnership with The Alliance for Artificial Intelligence in Healthcare (AAIH). I expect several technologies to converge across the healthcare spectrum this year.
AI Predicts Which Women Will Develop Breast Cancer and Those Who Will Not
In September, AI researchers at the AI Precision Health Institute at the University of Hawaiʻi Cancer Center published two high profile papers demonstrating for the first time that deep learning can distinguish between mammograms of women who will develop breast cancer and those who will not. In one paper the researchers confirmed that invasive breast lesions have unique compositional signatures and demonstrated that compositional profiles of the breast combined with CAD predictions can improve the detection of malignant breast cancer. In the other paper researchers showed that deep learning models performed better than models using clinical risk factors in determining screening-detected cancer risk. There are multiple AI algorithms approved by the FDA for detecting breast cancer. The best of these algorithms have a sensitivity of 82% in the detection of breast cancer, with a fixed specificity of 96.6%. Using this deep learning algorithm with a radiologist improved the sensitivity by 8%. Note: I’m on the advisory board at the AI Precision Health Institute. I follow their work closely and I frequently write about their research.
AI Identifies Live Cancer Cells In Less Than 35 Minutes With 95% Accuracy
Researchers at National University of Singapore developed a novel protocol using AI and inexpensive equipment to identify live cancer cells in less than 35 minutes with 95% accuracy. Yuri Belotti, PhD, Doorgesh Sharma Jokhun, PhD, and Professor Chwee Teck (C.T.) Lim developed a novel protocol for single-cell classification based on intracellular pH. Since cancer cells have different intracellular acidity than normal cells, the AI algorithm identified cancer cells by examining the level of acidity. They used a pH-sensitive dye that changes color according to the level of acidity. Using AI they were able to quantitatively map the unique acidic fingerprints so that the cell types examined can be easily and accurately identified. They were able to discriminate between normal and cancer cells, discriminate between benign and metastatic cells, and classify cancer cells that originated from different organs. Current techniques like fluorescent probes induce toxic effects and can kill the cells, whereas the new technique does not kill cells. This novel method opens up the potential to perform rapid noninvasive identification of living cancer cells for early cancer diagnosis and further downstream analyses. The paper was published in APL Bioengineering.
AI Algorithm Helps Hospitals Reduce Missed Fractures By 29%
In December, Gleamer AI demonstrated that their algorithm can quickly detect and flag X-rays with positive fractures helping hospitals reduce missed fractures by 29%. Due to the large number of X-rays that have to be read by radiologists, patients often have to wait hours in the ER before they can be seen, evaluated, and receive treatment. Fracture interpretation errors represent 24% of harmful diagnostic errors in the ER. Inconsistencies in diagnosis of fractures are most common between 5pm and 3am due in part to fatigue. In this retrospective diagnostic study, a dataset of 480 X-rays was read by 24 readers who assessed the X-rays with and without AI. To simulate real life scenario the study included readers from many disciplines including radiologists, orthopedic surgeons, emergency physicians, physician assistants, rheumatologists, and family physicians, all of whom read X-rays real clinical practice to diagnose fractures in their patients. Each reader’s diagnostic accuracy of fractures, with and without AI assistance, were compared against the gold standard. They also assessed the diagnostic performance of AI alone against the gold standard. The AI model was trained on a large x-ray data set from multiple hospitals to identify limb, pelvis, torso, lumbar spine, and rib cage fractures. The AI increased sensitivity by 16% for exams with 1 fracture and by 30% for exams with more than 1 fracture. The AI algorithm can quickly detect and flag X-rays with positive fractures so that radiologists can prioritize reading them.
FDA Approves First Ever AI-Based Pathology Product
In September, in a historic milestone, the FDA approved the first ever AI-based pathology product approved for clinical use. Paige Prostate is the first and only AI-based pathology product to receive FDA approval for in vitro diagnostic use in detecting cancer in prostate biopsies. FDA approval allows pathology laboratories to use Paige Prostate to help make diagnosis more accurate, more reproducible, and more efficient. The number of cancer cases worldwide is projected to increase by 60% over the next two decades. Since there will be a decrease in the number of pathologists relative to demand, there is a significant need for new technologies for use in pathology. After non-melanoma skin cancer, prostate cancer is the most common cancer among men in the US and one of the leading causes of cancer death in men. Paige Prostate is a clinical-grade AI solution designed to identify foci that could indicate cancer, enabling fast, accurate in vitro diagnosis. Pathologists using the technology have been shown to significantly increase their capabilities to accurately and effectively find prostate cancer. This landmark approval of Paige Prostate by the FDA marks the beginning of a new era in the use of AI in pathology and paves the way for new innovations using AI in diagnostics.

The company plans to partner with biomedical and pharma companies using AI to discover new medicines. DeepMind CEO Demis Hassabis will also serve as the CEO for Isomorphic, but the two companies will stay separate and collaborate occasionally. Hassabis chose Isomorphic as the company name because he believes that there may be an underlying structure between biology and information science. In science, isomorphic refers to things that share a common form or relationship. Isomorphic is building a world-class multidisciplinary team, with deep expertise in AI, biology, medicinal chemistry, biophysics, and engineering.
Neuroscientists Use AI Algorithms To Analyze Enormous Datasets
In September, Leucadia Therapeutics published and important paper on a new treatment that could potentially prevent Alzheimer’s. The paper decribed how Leucadia developed AI algorithms to analyze enormous datasets to help predict risk of Alzheimer’s disease. The new approach incorporates cutting-edge deep learning applied to an advanced method for ultra-resolution contrast-enhanced micro-CT, a novel animal model, and a large clinical study designed to produce highly curated data for machine learning. 3D U-Net segmentation is an architecture based on the Convolutional Neural Network, which is typically used to classify labels. However, in medical imaging 3D U-Net can do more than just classify. It contains localization to predict the class label of each pixel by providing a local region around that pixel as an input. Dr. Ethell and his team used 3D-UNet to train models with extremely high-resolution samples from post-mortem micro-CT samples. He then used those models to predict bone patterns from low-dose clinical CT scans that have lower resolution. The AI algorithms developed by Leucadia identify edges, boundaries, and holes to reveal where apertures occur and how large they are using a low-dose cone-beam CT scan.
AI Outperforms Traditional Methods Predicting Heart Attack and Stroke
In November, Owkin and Amgen demonstrated that machine learning techniques are more accurate at predicting risk of severe cardiovascular disease than traditional clinical methods. The study included 13,700 participants in the placebo group of an Amgen clinical trial evaluating the cholesterol drug Repatha, Owkin’s AI algorithms accurately identified which patients were at the highest risk for death, heart attacks or stroke over 3+ years. Owkin compared several AI approaches and used hundreds of different clinical variables. The best-performing model used age, medical history, smoking status, cholesterol count, kidney function, diabetes, —but also identified less-common variables that could help doctors predict people at highest risk of cardiac events. The study was published in The European Heart Journal Digital Health on November 15th.

Microsoft Announces Azure OpenAI Service
In November, Microsoft announced Azure OpenAI Service. The Service provides OpenAI’s machine learning models and access to GPT-3 – the world’s most advanced AI system capable of human-like dialogue. OpenAI was founded in 2015 by Elon Musk and Sam Altman, and other investors including Reid Hoffman and Peter Thiel who invested $1 billion. In 2019 Microsoft partnered with OpenAI and and invested $1 billion. GPT-3 is the third iteration of OpenAI’s Generative Pre-Trained Transformer model. Current GPT-3 features include powerful search, conversation, idea generation, text completion, and other advanced AI features. Most AI systems are designed for one use-case but GPT-3 provides a general-purpose “text in, text out” interface. Given any text prompt, the API will return a text completion. GPT-3 is extremely good at conversing with humans and it can even converse with itself. The key to success with GPT-3 is figuring out how to prompt the API. When given appropriate prompts, GPT-3 responds to questions with sophisticated and creative answers. Codex is like GPT-3, but instead of being trained on natural languages, it is trained on code, which allows users to generate new code, and even create entire sections. GPT-3 derivative, Codex, helps developers write code more efficiently and avoid repetitive tasks with automatic code completion and suggestions. Azure OpenAI Service will allow people to convert natural language into software code, summarize massive amounts of text, and generate answers to questions.
