Pseudo-continuous ASL (PCASL) based vascular territory mapping enables the detection of source arteries. An automated vascular territory segmentation using connectivity information from both image space and label space is proposed. The algorithm was tested with data obtained at two locations with middle cerebral artery branching. The algorithm demonstrates the ability to resolve neighboring sources into separate territories with minimal computational burden.
