摘要
目的探讨并比较新发和陈旧腔隙性脑梗塞的定量CT特点。方法对18个新发腔隙性脑梗塞灶和28个陈旧性腔隙性脑梗塞灶实施平扫CT和MRI检查。分别测量病灶CT值、大小和噪声值并进行相关的统计学分析。结果本组病例新发腔隙性脑梗塞灶的CT值与陈旧性梗塞灶CT值平均值分别是(22.56±0.72)HU和(12.27±0.67)HU,二者差异有统计学意义(<0.05)。结论CT值可以对新发及陈旧腔隙性梗塞的鉴别诊断有一定价值。
Objective To discuss and compare the quantitative CT values of fresh and olden lacunar infarctions.Methods Plain CT and MRI were performed in 18 cases of fresh lacunar infarction and 28 cases of olden lacunar infarction.The CT values,size and noise were measured respectively and analyzed statistically.Results The mean CT values of fresh and olden lacunar infarctions were （22.56±0.72） HU and （12.27±0.67） HU respectively,and the difference between the two groups had statistical significance（P0.05）.Conclusion The CT values are important factor in the differential diagnosis of the fresh and olden lacunar infarction.
