Researchers discussed how they used a deep-learning algorithm to detect, quantify, and assess the severity of infarcts in the brain on diffusion-weighted MRI (DWI-MRI) exams in acute ischemic stroke patients in a Sunday presentation at the virtual RSNA 2020 meeting.
In testing, the algorithm yielded:
•Average Dice coefficient: 0.85
•Average Dice coefficient when excluding extremely small lesions: 0.89
•Sensitivity: 83%
•Specificity: 99%
•Average volume difference for lesions calculated by model with those calculated by radiologists: 0.25 ml
