WebBrain perfusion, or the cerebral perfusion pressure (CPP), depends on the difference between the mean arterial pressure (MAP), traditionally measured at the level of the carotid artery siphon, and the ICP. Under normal circumstances, brain perfusion is autoregulated, and cerebral blood flow is maintained above a lower limit of 50 mm Hg. WebBrain perfusion SPECT is a method for imaging regional cerebral blood flow (Accorsi, 2008). 99m Tc-HMPAO (hexamethylpropyleneamine oxime) and 99m Tc-ECD (ethylene …
