[摘要] 目的 分析CT与MRI对腔隙性脑梗死的诊断价值。方法 方便选择该院自2015年1月—2017年11月收治的126例确诊为腔隙性脑梗死的患者,均做头颅CT及MRI,对比2种检查方法结果。结果MRI小病灶检出率为34.46%(234/679)明显高于CT检出率2.32%(6/259),相对比,差异有统计学意义(χ2=8.498 3,P<0.05)。MRI额叶病灶检出率为39.62%明显高于CT检出率7.72%,内囊检出率为4.71%明显低于CT检出率33.98%,相对比,差异有统计学意义(χ2=8.398 9,6.874 2,P<0.05)。两种检查方法所需费用及检查时间对比,MRI相对较高,差异有统计学意义(P<0.05);MRI检查所需时间为(21.09±4.87)min,所需费用为(1 103.48±7.86)元。结论 采用MRI可在早期检测出腔隙性脑梗死,且有较高的确诊率,值得应用。

[Abstract] Objective This paper tries to analyze the CT and MRI diagnosis of lacunar infarction. Methods 126 patients diagnosed as lacunar infarction in this hospital from January 2015 to November 2017 were examined by CT and MRI respectively. The results of two methods were compared. Results The detection rate of small lesions in MRI was 34.46% (234/679), significantly higher than that of CT 2.32%,(6/259), the difference was statistically significant(χ2=8.498 3,P<0.05). The detection rate of frontal lobe MRI was 39.62%, significantly higher than the CT detection rate of 7.72%, MRIIA capsule detection rate of 4.71% was significantly lower than the CT detection rate of 33.98%, the relative ratio were significantly different, the difference was statistically significant(χ2=8.398 9, 6.874 2, P<0.05);comparison of cost and examination time between the two methods of examination, the MRI was relatively high, and the difference was statistically significant(P<0.05). MRI examination time (21.09±4.87)min, the required cost of (1 103.48±7.86)yuan. Conclusion The use of MRI in the early detection of lacunar infarction, and a high rate of diagnosis, it is worth application.

脑血管疾病中有一种的特殊类型为腔隙性脑梗死,由小动脉硬化所致。该疾病可引起脑组织一系列病变,如缺血、水肿及坏死,病变范围较小,由受损的脑深部白质穿支小血管所致。对人体有较大的损害,使其失去部分功能,如运动、语言及感觉等,甚至导致死亡,需及时的发现并积极干预。然腔隙性脑梗死的病灶部位较深,且直接较小,需采用有效的检查方法协助诊断,以对病灶部位及大小进行了解[1-2]。影像学检查是诊断该疾病重要方法,头颅CT及MRI检查是常用的两种方法,为探究两组检查的具体效果,现方便选择该院自2015年1月—2017年11月收治的126例腔隙性脑梗死患者作为研究对象,现报道如下。
