目的 综合对比分析MRI（磁共振 成像）联合CT和单一CT在脑梗死患者中的 诊断效果，为治疗脑梗死患者提供科学 的数据参考。方法 选取我院在2014年12 月-2015年12月收治的脑梗死患者临床资 料46例，按照患者意愿随机分为实验组与 对照组，每组均为23例。实验组应用磁共 振成像(MRI)联合CT的诊断方法，对照组 应用单一CT的诊断方法。采用SPSS21.0统 计学软件进行统计学分析实验组与对照组 两组患者的正确诊断率、灵敏度、特异 度以及CT图像、磁共振成像图像等。结 果 实验组诊断检查发现有20例脑梗死疾 病患者，42个梗死病灶，正确检出率为 86.96%(20/23)，对照组诊断检查发现有 15例脑梗死疾病患者，31个梗死病灶，正 确检出率为65.22%(15/23)，实验组的正 确诊断率远远高于对照组，数据比较差异 有统计学意义(P<0.05)；实验组患者的 灵敏度、特异度分别为92.3%、82.3%， 对照组患者的灵敏度、特异度分别为 82.3%、75.6%，数据比较差异有统计学意 义(P<0.05)。结论 在脑梗死患者的相关 诊断中，MRI(磁共振成像)联合CT的诊断 效果远远优于单一CT的诊断效果。

Objective Comprehensive comparative analysis of MRI (magnetic resonance imaging) combined with CT and single CT in patients with cerebral infarction in the diagnosis of results, to provide scientific data for the treatment of patients with cerebral infarction. Methods In our hospital clinical data of patients with cerebral infarction in December 2014 -2015 year in December 46 cases, according to the wishes of patients were randomly divided into experimental group and control group, each group had 23 cases. The experimental group used magnetic resonance imaging (MRI) diagnosis method combined with CT, the control group using a single diagnosis method CT. Statistical analysis of the experimental group and the control group of two patients with correct diagnosis rate, sensitivity, specificity and CT images, magnetic resonance imaging images using SPSS21.0 statistical software. Results Diagnosis of the experimental group was detected in 20 cases of cerebral infarction patients, 42 infarct lesion, the correct detection rate was 86.96% (20/23), the control group diagnosis found 15 cases of cerebral infarction patients and 31 infarction lesions, the correct detection rate was 65.22% (15/23) in the experimental group, the correct diagnosis rate is much higher than that of the control group, the data, the difference has statistical significance (P<0.05). The patients in the experimental group the sensitivity and specificity were 92.3% and 82.3%, the control group, the sensitivity and specificity were 82.3% and 75.6%, the differences were statistical significance (P<005). Conclusion MRI (magnetic resonance imaging) combined with CT in the diagnosis of cerebral infarction patients is far superior to the diagnostic results of single CT.
