Noninvasive measurement of arterial blood plasma concentration of iodinated contrast agents from CT scans of human brain.

abstract：OBJECTIVE:We examined the relationship between the perfusion reserve as measured by acetazolamide (ACZ)-challenge N-isopropyl-I-123-p-iodoamphetamine (IMP)-single-photon emission computed tomography (SPECT) and the degree of leukoaraiosis (LA) as estimated using magnetic resonance imaging. METHODS:In 51 patients recei...
