分水岭(WS)梗塞的机制仍有争议,作者研究了WS梗塞的部位和脑循环血液动力学之间的关系。用~(123)I—IMP(碘代苯异丙胺)单光子发射断层显像(SPECT)定量测定局部脑血流(rCBF)和局部灌注储备。
The mechanism of the watershed (WS) infarct is still debated. The authors studied the relationship between the infarct site of WS and the cerebral circulation hemodynamics. Quantitation of regional cerebral blood flow (rCBF) and local perfusion reserve with ~ (123) I-IMP (iodoamphetamine) single photon emission computed tomography (SPECT)
