脑血管病时局部脑血流急性脑梗塞很多研究证明闭塞性脑动脉疾患不论是血管造影证实或造影阴性者局部脑血流(rCBF)均有改变,尤其后者局部脑血流测定更有诊断价值。急性脑梗塞脑血流呈普遍性降低,同时脑氧消耗量亦降低,不仅受累半球如此而且对侧半球亦有同样改变,称为神经机能联系不能(Diaschisis),测定局部脑血流可以明确辨别局部缺血区及边 Cerebral vascular disease local cerebral blood flow acute cerebral infarction Many studies have shown that occlusive cerebral artery disease, whether angiography confirmed or contrast-negative local cerebral blood flow (rCBF) have changed, especially in the latter part of the diagnosis of local cerebral blood flow more value. Cerebral blood flow in acute cerebral infarction is generally reduced, while cerebral oxygen consumption is also reduced, not only in the affected hemisphere but also in the contralateral hemisphere also have the same change, called neurological dysfunction (Diaschisis), determination of regional cerebral blood flow can be clearly identified Ischemic area and border
