MR perfusion imaging has become an important tool in the assessment of cerebrovascular disease. A commonly used technique to quantify MR perfusion results is to have a physician manually draw ROIs in different vascular territories, but this is a time consuming and subjective process that can introduce bias. Here we propose a method for automatically constructing subject-specific vascular territory ROIs and validate the method in cohorts of ischemic stroke patients and healthy volunteers.
