核医学对局部脑血流评价较早。自应用133xe颈内动脉注入法和吸入法后报导较多。由于操作复杂,没有被广泛普及。应用阳电子核标记各种有机化合物,对脑血流及各种脑代谢进行测定。但价格昂贵,耗费人力。Winchell氏等用N-异丙基-P〔~(123)I〕碘苯异丙胺(IMP),静注后至脑组织内转移率高,排出缓慢。这种新的制剂利用于局部脑血流引人注目。单光于发射计算机断层摄影术(SPECT)引起了重视。本文以脑血管障碍性疾病为主,应用IMP进行
Nuclear medicine on the evaluation of local cerebral blood flow earlier. Since the application of 133xe carotid artery injection and inhalation method reported more. Due to the complicated operation, it has not been widely popularized. Application of the positron nuclear marker of various organic compounds, cerebral blood flow and various brain metabolism were measured. But expensive, labor-intensive. Winchell et al with N-isopropyl-P 〔~ (123) I〕 iodine isopropylamine (IMP), intravenous injection into the brain tissue after the high rate of transfer, slow discharge. This new formulation is used for striking local cerebral blood flow. Single-photon emission computed tomography (SPECT) attracted much attention. This article mainly cerebrovascular disorders, the application of IMP
