101例脑血管疾病患者脑血流灌注显像分析

Evaluation of rCBF Imaging of 101 Patients with CVD

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。

Objective:The results of the cerebral blood flow imaging of cerebrovascular disease wereanalysed and compared with that of X-CT. Method: ^(99m)Tc-ECD SPECT was used to image the cerebralblood flow in 101 CVD patients including cerebral infarction, cerebral hemorrhage, TIA and vertebralbasal artery insufficiency(VBI). Results: The positive rate of SPECT was 88% and that of X-CT was78% respectively .The abnormal rCBF images varied from ischaemia to hyperperfusion. 37% cases haveischemic lesions, 82% decreased lesions, 30% hyperperfusion and 15% CCD. Conclusions: rCBF SPECTimaging is useful to study the rCBF change of patient with CVD .The clinical values of diffrent abnormalperfusion lesions should be studied more.
