摘要
目的对照研究CT与磁共振在腔隙性梗死诊断中的临床意义。方法选取安阳市肿瘤医院2013-02—2015-07收治的腔隙性梗死患者80例,所有患者行CT与磁共振检查,对诊断结果进行分析对比。结果病理检查检出病灶385例,磁共振检查共检出病灶360个(93.5%),CT检测出153个(39.7%),病灶位置包括丘脑、小脑、颞叶、基底节、额叶、枕叶、顶叶、脑干,磁共振检查病灶检出率明显高于CT(P<0.05);两种检测方法的检出率对比差异有统计学意义(P<0.05)。两种检查方法病灶大小对比差异有统计学意义(χ2=8.134,P<0.05);两种检查方法检查时间、病灶大小、检查费用对比差异有统计学意义(P<0.05);磁共振检查主要呈小片斑块状,T1、T2长信号,DWI加深,T2FLAIR高信号,CT检查影像主要呈低密度小片状、斑点状显影。结论 CT与磁共振均可用于腔隙性梗死诊断,但磁共振早期诊断价值以及病灶检出率明显优于CT检查,能够明确反映病灶的位置、大小及数量,便于后期及时有效治疗,值得在临床实践中推广应用。
Objective To study the diagnostic significance of CT and magnetic resonance in lacunar infarction.Methods A total of 80 patients with confirmed lacunar infarction in Anyang Tumor Hospital were selected in this study.All patients received CT and nuclear magnetic resonance,and the diagnostic effects were compared between two inspection methods.Results A total of385 lesions were found by pathological examination,360 lesions were found by magnetic resonance(93.5%),and 153 lesions were found by CT(39.7%).The location of the lesion includes thalamus,cerebellum,temporal lobe,basal ganglia,frontal lobe,occipital lobe,parietal lobe,brainstem.The total number of lesions found by magnetic resonance was significantly more than that found by CT,with statistical difference(P<0.05).There were significant differences in the time of examination,the average size of lesions and the cost of examination between the two examinations(P<0.05).Magnetic resonanceshowed small pieces images,long signal of T1,T2,significantly deepened DWI,and high signal of T2FLAIR;CT showed low-density small pieces or patchy images.Conclusion CT and magnetic resonance can be used for the diagnosis of lacunar infarction,but magnetic resonance is better than CT in the early diagnosis and lesion detection rate,which can clearly reflect the location,size and quantity of the lesion.It is convenient for timely and effective treatment in later stage,and is worth popularizing in clinical practice.
