AI software flags missed intracranial aneurysms on CTA

Thursday, November 30 | 9:40 a.m.-9:50 a.m. | R3-SSNR15-2 | Room S402In this talk, researchers from Tel Aviv University in Israel will describe how an AI algorithm can retrospectively detect intracranial aneurysms that had been missed on CT angiography (CTA) exams.It’s crucial to identify intracranial aneurysms early, as early detection facilitates risk stratification and timely, optimal management, according to presenter Tamer Sobeh, MD, of Tel Aviv University.“The increasing workload for radiologists to detect [intracranial aneurysms], particularly incidental cases in the non-subarachnoid hemorrhage setting, underscores the need for high-performance computer-assisted diagnosis tools to improve efficiency and increase sensitivity,” they wrote.The researchers retrospectively applied a commercial deep-learning system to 2,617 CTA cases acquired at their institution. Of these, 127 (4.7%) included an intracranial aneurysm.The algorithm flagged 34 cases as suspected missed aneurysms, and 23 (67%) were deemed by a minimum of two out of three neuroradiologists as true-positive aneurysms. That translates to a 23% enhanced detection rate, according to the researchers.“The study demonstrates the potential of deep learning systems as a secondary reader in identifying missed intracranial aneurysms, some of which could be clinically significant,” the authors concluded.What else did they find? Stop by this Thursday session for more information.
