vascular territory mapping
The delineation of brain regions supplied by specific arterial vessels to assess perfusion patterns and stroke risk.
Full Definition
Vascular territory mapping involves the identification and demarcation of brain regions that receive blood supply from individual arterial vessels, including the anterior, middle, and posterior cerebral arteries and their branches. This mapping is crucial for understanding stroke patterns, planning revascularization procedures, and interpreting perfusion deficits. Modern neuroimaging techniques, including arterial spin labeling and time-resolved angiography, enable non-invasive assessment of vascular territories and can reveal variations from normal anatomy. Editors reviewing stroke and cerebrovascular literature must understand this concept to properly evaluate studies correlating clinical deficits with vascular anatomy and assess treatment planning approaches.
Usage
Usage note: Often requires specification of the imaging technique and vessel labeling method used.
