摘要
本文应用^(99m)Tc-ECD对12例正常人和75例各种脑部疾病的γCBF显像进行了半定量分析,通过ROI测定病灶区与小脑比值。在正常组各叶/小脑比值平均为O.955,而52例γCBF减低的患者,病灶区/小脑比值仅O.770,两组间有显著差异(P<O.001),3例γCBF增加者比值均>1.05。结果表明,本法是评价γCBF显像简便、准确的半定量指标。
Semi-quantitative analysis of ^(99m)Tc-ECDγCBF imaging were performed in 12 normal control and 75 patients with varied brain diseases. The lesions/cerebellum ratio was measured by ROI. Average ratios were 0.955 and 0.770, respectively, for both 12 normal control and 52 patients with γCBF decreased (P<0.001). In the 3 patients whom γCBF increased, it were more than 1.05. These results show that it is a simple and accurate method to analysis γCBF imaging.
