Deep Learning: An Example of Big Data Applications

Thursday, Dec. 3, 4:30-6:00 p.m. Room S105AB
Deep learning is a new paradigm that automatically discovers clinically-relevant features by first architecting a hierarchy of patterns (loosely modeled on the brain's own neural networks) and updating those patterns upon observing examples. As radiology requires complex associative pattern recognition, deep learning is the ideal companion tool. In this session, presenters will offer a technical overview of machine learning and deep learning, illustrate its applications in radiology, and detail some of the challenges improving radiologic workflow using deep learning poses.

The Safety and Efficacy Profile of TACE for Treating Hepatocellular Carcinoma in Patients Co-infected with HIV and HCV: A Propensity Score Matching Study

Wednesday, Dec. 2, 12:15-12:45 p.m., Vascular Interventional (VI) Community, Learning Center, Station #4
Hepatocellular carcinoma (HCC) is becoming an increasing cause of morbidity and mortality in patients co-infected with HIV and HCV. Transcatheter arterial chemoembolization (TACE) is an important treatment option for unresectable HCC, but to date, there is insufficient data on the safety and efficacy profile of TACE in this specific cohort. In this study, researchers compare HCC patients with HIV/HCV co-infection treated with TACE against HCC patients with HCV mono-infection treated with TACE through survival analysis and recording of major complications.
