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.
