Table 1. Indications for CT Perfusion Imaging
Disease Process	Functional Information
Stroke	CBF identifies potentially salvageable “ischemic penumbra” CBV identifies likely to be irreversibly damaged infarct “core”
Carotid Occlusive Disease	CTP with diamox challenge or breath hold to assesses cerebrovascular reserve capacity
Aneurysm Rupture	CTP parameters help distinguish “angiographic” from hemodynamically significant vasospasm following subarachnoid hemorrhage (SAH)
Brain Tumors	CBV, CBF, and permeability maps correlate with tumor grade, help localize biopsy sites, and help to distinguish post-treatment changes from recurrent tumor
Other	CTP data potentially of value in detecting and delineating dementing and other neurodegenerative diseases
