Stroke lesion localization in 3D MRI datasets with deep reinforcement learning

In person: 22 February 2022 • 11:30 AM - 11:50 AM PST

Abstract

The efficacy of stroke treatments is highly time-sensitive, and accelerated diagnosis may improve patient outcomes. Lesion identification in MRI datasets is time consuming and challenging. Automatic lesion localization can expedite diagnosis by flagging images and corresponding regions of interest for visual assessment. In this work, we propose a deep reinforcement learning model to localize and detect ischemic stroke lesions in fluid attenuated inversion recovery MRI images, combining advances in computer vision to sequentially localize multiple lesions. The results show that the model learns to successfully localize lesions in challenging hybrid data from multiple studies.
