Reducing False-Positives in CT Perfusion Infarct Core Segmentation Using Contralateral Local Normalization [NEUROVASCULAR/STROKE IMAGING]

CONCLUSIONS: The proposed method of local normalization can reduce overestimation of the infarct core, especially in the deep WM and in cases with obvious microangiopathy. False-positives in CTP infarct core segmentation might lead to less-than-optimal therapy decisions when not correctly interpreted. The proposed method might help mitigate this problem.
