Predicting Stroke Etiology with Radiomics: A Retrospective Study.

: The composition of the thrombus is not taken into account in the etiology determination of patients with acute ischemic stroke (AIS); however, it varies depending on the origin of the thrombus, as atherothrombotic thrombi contain more red blood cells and cardioembolic thrombi contain more fibrin and platelets. Radiomics has the potential to provide quantitative imaging data that may vary depending on the composition of thrombi. The aim of this study is to predict cardioembolic and atherothrombotic thrombi using radiomic features (RFs) from non-contrast computed tomography (NCCT) brain scans.
