70472 CT cere prfu alys c+with CT/cta
Also known as: CT perfusion, CTP, perfusion CT with angiography, brain perfusion study
Computed tomographic perfusion analysis of the cerebrum with intravenous contrast and concurrent computed tomographic angiography. Measures cerebral blood flow, blood volume, and mean transit time to evaluate tissue viability.
In Plain Language
blood flow scan of brain; tissue viability study
Clinical Context
Critical in acute stroke triage to identify tissue at risk of infarction. Helps distinguish irreversibly infarcted tissue from salvageable penumbra, guiding thrombolytic and thrombectomy decisions. Also used for brain tumor evaluation.
