目的：探讨双排螺旋CT与0.3T MRI用于脑梗塞早期的临床诊断效果，评价其应用价值。方法选取2013年3月-2015年3月我院神经内科收治的64例脑梗塞患者，在发病6h以内按诊断方法不同定义为对照组(32例，双排螺旋CT)，观察组(32例，0.3T MRI)，对比两组患者的诊断准确率、病灶阳性检出率及影像学表现。结果观察组患者诊断准确率(96.9%)与对照组(68.8%)相比，P＜0.05，差异显著；两组患者的基底节、内囊、额叶、顶叶、脑干、丘脑、小脑等病灶阳性检出率比较χ2分别为5.02、3.95、34.71、4.16、4.13、3.99、4.57，P＜0.05，差异有统计学意义；MRI图像清晰度、分辨率优于CT图像。结论较CT比较，MRI诊断早期脑梗塞具敏感性强、分辨率高、图像清晰等优点，可提高诊断准确率和病灶阳性检查率，利于患者及时治疗，具有较高临床应用价值。

Objective To explore the efficacy of double-slice helical CT and 0.3 T MRI applied in clinical diagnosis on early cerebral infarction and to evaluate its application value.Methods Sixty four patients with cerebral infarction admitted by the department of neurology of the Hospital from March, 2013 to March, 2015 were selected, who were defined into the control group (32 cases, double-slice helical CT) and the observation group (32 cases, 0.3 T MRI) within 6 hours of the onset according to different diagnostic methods. Positive detection rate and diagnosis accuracy, lesions imaging manifestations of patients in two groups were compared.Results The diagnosis accuracy (96.9%) on patients in the observation group satisfied P<0.05 when compared to that of patients in the control group (68.8%), and the difference was significant. The comparison in positive detection rate of basal ganglia, internal capsule, frontal, parietal lobe, brain stem and thalamus and cerebellar lesionχ2 satisfied 5.02, 3.95, 34.71, 4.16, 4.13, 3.99 and 4.13 (P<0.05), the differences were statistically significant. The resolution of MRI image was better than that of CT image.Conclusions MRI diagnosis on early cerebral infarction deliver advantages including strong sensitivity, high resolution and clear image, improve diagnostic accuracy and positive rate of examination on lesions, which facilitate timely treatment of patients and impose high clinical value.
