Towards discrimination of infarcts from artifacts in DWI scans


Accurate and rapid quantification of infarcts from DWI scans is critical in acute ischemic stroke. Acquisition artifacts lead to hyperintense regions in DWI MR scans resulting in false positives. Discriminating infarcts and artifacts helps in reducing infarct segmentation errors. An algorithm based on two-dimensional symmetry of artifacts about the… (More)
