对101例脑血管疾病患者~(99m)TcECD SPECT脑血流灌注显像结果进行分析并与X—CT显像进行比较。101例中,男83例,女18例。脑梗塞69例,脑出血18例,TIA6例,椎动脉供血不足8例。其中78例有X—CT显像结果。结果:脑血流灌注显像阳性率88％,其中脑梗塞94％,脑出血94％,TIA50％,椎动脉供血不足50％。脑血流灌注显像异常表现呈多样性。有缺血灶病例占37％,灌注减少82％,过度灌注30％,15％的病例出现CCD现象。X—CT显像阳性率78％,同样的病例脑血流灌注显像阳性达94％。结论:SPECT脑血流显像对脑血管疾病脑血流的研究有较大价值,其各种显像异常表现的临床价值有待深入研究。
The results of ~ (99m) TcECD SPECT perfusion imaging in 101 patients with cerebrovascular disease were analyzed and compared with X-ray CT. 101 cases, 83 males and 18 females. 69 cases of cerebral infarction, 18 cases of cerebral hemorrhage, TIA6 cases, vertebral artery insufficiency in 8 cases. 78 cases had X-CT imaging results. Results: The positive rate of cerebral perfusion imaging was 88%, including 94% cerebral infarction, 94% cerebral hemorrhage, 50% TIA and 50% vertebral artery insufficiency. Cerebral perfusion imaging abnormalities showed a diversity. There are 37% cases of ischemic lesions, perfusion decreased 82%, over-perfusion 30%, 15% of the cases of CCD phenomenon. X-CT imaging positive rate of 78%, the same case of cerebral perfusion imaging positive 94%. CONCLUSION: SPECT cerebral blood flow imaging is of great value in the study of cerebral blood flow in cerebrovascular diseases. The clinical value of various imaging abnormalities remains to be further studied.
