目的 分析腔隙性脑梗死早期CT 和MRI检查的临床影像学表现。方法 统计 分析2012年5月至2015年5月我院收治的早 期腔隙性脑梗死患者80例的临床资料。结 果 80例患者中，在额叶、顶叶、内囊、 丘脑、小脑、基底节、脑干等发病部位， CT检查发现143个病灶，MRI检查发现740 个病灶，MRI检查发现的病灶数量显著多 于CT(P<0.05)；MRI检查直径<5mm病灶255 个，>5mm病灶485个，小病灶和大病灶检 出率分别为34.5%、61.9%；CT检查直径 <5mm病灶3个，>5mm病灶140个，小病灶和 大病灶检出率分别为2.1%、97.9%。MRI检 查小病灶检出率显著高于CT(P<0.05)，大 病灶检出数量显著多于CT(P<0.05)。结论 早期腔隙性脑梗死MRI较CT更能清晰准确 地发现微小病灶，可以作为临床诊断的重 要检查方法。

Objective To analyze the clinical imaging of early implementation of CT and MRI in the diagnosis of lacunar infarction. Methods The clinical data of 80 cases of early lacunar infarction patients who were treated in CT / MRI room of Daye City People's Hospital from May 2012 to May 2015 were statistically analyzed. Results Among the 80 cases of patients, the onset of the prefrontal, parietal lobe, internal capsule, thalamus, cerebellum, basal ganglia, brain stem, CT examination revealed 143 lesions, MRI examination revealed 740 lesions, the number of lesions in MRI examination revealed significantly more than CT (P <0.05). MRI examination diameter <5mm lesion 255,> 5mm lesion 458, small lesions and large lesion detection rate was 34.5% and 61.9%, respectively. CT examination diameter <5mm lesion 3,> 5mm 140 lesions, small lesions and large lesion detection rate was 2.1%, 97.9% respectively. The detection rate of small lesion of MRI examination was significantly higher (P<0.05), the detection rate of large lesion was significantly lower than CT (P<0.05). Conclusion Early implementation of MRI is better than CT in searching out lacunar infarction tiny lesions clearly and accurately, it can be an important method for clinical diagnosis.
