目的对比腔隙性脑梗死CT与MRI表现并探讨在腔隙性脑梗死诊断中的价值。方法对180例临床疑似腔隙性脑梗死患者在常规头颅CT、MRI的基础上行FLAIR、DWI和MRA检查,根据影像学结果进行对比分析,选择治疗方案。结果①MRI可以确诊疑似病例患者是负腔隙性脑梗死;②FLAIR可以发现早期脑缺血灶;③DWI可显示常规CT和MRI T1W1、T2W1不能显示的病灶(新鲜病灶)。④MRA显示血管闭塞的部位和狭窄程度。结论通过比较影像学早期诊断腔隙性脑梗死,显示梗死灶与靶血管的关系,早期临床体征可提供切实可行的影像学资料。
Objective To compare the CT and MRI findings of lacunar infarction and explore its value in the diagnosis of lacunar infarction. Methods 180 patients with clinically suspected lacunar infarction were examined by FLAIR, DWI and MRA on the basis of conventional craniocerebral CT and MRI. According to the imaging results, comparative analysis was made and the treatment options were selected. Results ①MRI can be diagnosed in patients with suspected negative lacunar infarction; ② FLAIR can be found in early ischemic lesions; ③ DWI can show conventional CT and MRI T1W1, T2W1 lesions can not be displayed (fresh lesions). ④ MRA showed the location of vascular occlusion and stenosis. Conclusion Comparing the early diagnosis of lacunar infarction by imaging, showing the relationship between infarction and target vessel, early clinical signs can provide feasible imaging data.
