目的:比较早期腔隙性脑梗死的头颅计算机体层成像(CT)及磁共振成像(MRI)的特点,探讨CT、MRI对早期腔隙性脑梗死的诊断价值。方法:回顾性分析2009年1月至2011年12月40例早期腔隙性脑梗死患者头颅CT及MRI的临床资料。结果:本组40例中,CT、MRI发现腔隙性脑梗死灶分别为261个和39个,MRI发现的腔隙性脑梗死病灶数目非常显著多于CT。结论:磁共振成像检查早期腔隙性脑梗死较CT敏感、准确,可作为诊断早期腔隙性脑梗死的首选方法。
Objective: To compare CT and MRI features of early lacunar infarction and to evaluate the diagnostic value of CT and MRI in early lacunar infarction. Methods: The clinical data of 40 craniocerebral infarction patients with craniofacial CT and MRI from January 2009 to December 2011 were retrospectively analyzed. Results: In the group of 40 cases, lacunar infarcts were found to be 261 and 39 respectively by CT and MRI. The number of lacunar infarcts found by MRI was significantly higher than that of CT. Conclusion: Magnetic resonance imaging can detect early lacunar infarction as sensitive and accurate as early diagnosis of lacunar infarction.
