A post-game roundup by ITN Contributing Editor Greg Freiherr and ITN Editor Dave Fornell on the trends and new technology in radiology seen on the show floor at the Radiological Society of North America (RSNA) 2016 meeting.
At RSNA 2016, the key buzzwords were “deep learning,” “machine learning” and “artificial intelligence.” Vendors and major academic centers are developing a wide array of artificial intelligence neural networks to aid radiologists in clinical diagnosis and clinical decision support. In the future, AI may also be able to help train radiologists on both normal and abnormal presentations of various organs and body systems so as to more easily identify related disease states and conditions. The following video offers two examples of how the IBM Watson system examines imaging studies.
The first case seen here demonstrates how Watson can arrive at a differential diagnosis of an aortic dissection by analyzing an abdominal computed tomography (CT) scan. The second case involves the discovery of a fibroadenoma of the breast from Watson’s analysis of a mammogram.
Watson first analyzes the text of the radiology report, identifying and pulling out key words or phrases that may indicate the potential diagnosis. It then examines the CT scan to locate relevant visible anatomic structures such as the heart, aorta and pulmonary artery. Each structure is examined for anomalies, which identifies a possible aortic dissection; the dissection is displayed within the context of the entire 3-D CT scan. Finally, Watson applies its existing clinical knowledge to the findings from the CT scan and the radiology report, establishing pathways to numerous possible conclusions until arriving at the right one.

Gadolinium-based contrast agents have been used for diagnosis and treatment guidance in more than 100 million patients worldwide over the past 25 years. These agents enhance the quality of MR images by altering the magnetic properties of nearby water molecules in the body. By improving the visibility of specific organs, blood vessels or tissues, contrast agents help physicians diagnose and treat a wide variety of medical conditions. On its own, gadolinium can be toxic. Therefore, when used in contrast agents, gadolinium is bonded with a molecule called a chelating agent, which controls the distribution of gadolinium within the body.
Mark Michalski, M.D., director of the Center for Clinical Data Science at Massachusetts General Hospital, explains the basis of the utilization of artificial intelligence (aka deep learning and machine learning) in radiology. He also explains where things are at in development of these neuro networks at RSNA 2016. Watch the VIDEO “Examples of Artificial Intelligence in Medical Imaging Diagnostics.”
