Symmetric brain perfusion

WebAug 7, 2024 · The CT perfusion (CTP) is a medical exam for measuring the passage of a bolus of contrast solution through the brain on a pixel-by-pixel basis. CT perfusion is performed with a sampling time of approximately 1 Hz. Based on these measurements, low-dose serial scans are acquired from which blood time-density curves and several other … Cerebral perfusion pressure, or CPP, is the net pressure gradient causing cerebral blood flow to the brain (brain perfusion). It must be maintained within narrow limits because too little pressure could cause brain tissue to become ischemic (having inadequate blood flow), and too much could raise intracranial pressure (ICP).
