容量测定

Methods Perfusion weighted imaging was performed in 45 cases of cerebral infarction. The sidetoside ratios of regional cerebral blood flow,regional cerebral blood volume and mean transit time were measured at duty lesion of ischemia. The hypoperfused cerebral areas and the stages of ischemia were defined as follows:compensation stage: rCBF was normal, rCBVwas increased, MTT was prolonged;decompensation stage: rCBF was slightly decreased, rCBV was normal or decreased, MTT was prolonged;preinfarction stage: rCBF and rCBV were decreased,MTT was prolonged.
