Different ways of estimating post-reperfusion infarct volume have comparable results

Reuters Health - 21/01/2021 - In assessing post-reperfusion final infarct volume (FIV) and functional outcomes in certain stroke patients, noncontrast computed tomography (NCCT) e-Stroke Suite software performs similarly to RAPID computed tomography perfusion (CTP), according to a cross-sectional observational study. The e-Stroke Suite software uses a machine-learning algorithm to provide a fully automated means of quantifying The Alberta Stroke Program Early CT Score (ASPECTS) and ischemic-core volumes on NCCT, researchers write in Stroke. The approach has demonstrated sensitivity and specificity comparable to that achieved by experienced neuroradiologists in a various circumstances, Dr. Raul G. Nogueira of Emory University School of Medicine, in Atlanta, and colleagues add. However, they write, "the ability and accuracy of the e-Stroke Suite software to determine baseline ischemic core volumes has not been explored." The RAPID software, they say, is used as...
