摘要:
目的 探讨CT与MRI在急性脑梗塞患者早期诊断中的应用价值。方法 选取2019年1月~2020年1月我院收治的125例急性脑梗塞患者为研究对象，均行CT与MRI检查，比较MRI与CT对不同部位梗死灶检出率、病灶检出数目与大小、对不同大小病灶检出情况，并分析图像特征。结果 MRI检查对额叶、颞叶、基底节、枕叶、小脑、脑干部位脑梗塞检出率均高于CT检查（95.24% vs 61.90%）、（92.30% vs 61.54%）、（97.30% vs 62.16%）、（94.44% vs 61.11%）、（100.00% vs 30.00%）、（92.31% vs 46.15%），差异有统计学意义（P＜0.05）；MRI平均检出病灶数目多于CT，检出平均病灶大小小于CT，差异有统计学意义（P＜0.05）；MRI对≤5 mm病灶检出率高于CT（96.77% vs 18.82%），差异有统计学意义（P＜0.05）；MRI与CT对6~10 mm、≥11 mm病灶检出率比较，差异无统计学意义（P＞0.05）。图像特征：MRI表现为T1WI低信号、T2WI高信号，病灶形状以圆形、椭圆、条索状为主；5 mm以下病灶形状多数表现为斑点状、圆点状、针尖样，6~10mm病灶多数表现为椭圆。CT表现为病灶呈低密度表达，部分患者皮质、白质不清，部分可见豆状核镜界，岛叶结构界面欠清晰。结论 MRI对于不同部位梗死灶的检出率较高，且检出病灶数目较多，检出平均病灶大小较小，对急性脑梗塞早期诊断效果优于CT。
Abstract:
Objective To explore the application value of CT and MRI in the early diagnosis of patients with acute cerebral infarction.Methods 125 patients with acute cerebral infarction admitted to our hospital from January 2019 to January 2020 were selected as the research objects. CT and MRI were performed to compare the detection rate and number of infarcts at different locations with MRI and CT. Size, detection of lesions of different sizes, and analysis of image characteristics.Results The detection rate of cerebral infarction in the frontal lobe, temporal lobe, basal ganglia, occipital lobe, cerebellum, and brain stem by MRI was higher than CT examination (95.24% vs 61.90%), (92.30% vs 61.54%), (97.30% vs 62.16%), (94.44% vs 61.11%), (100.00% vs 30.00%), (92.31% vs 46.15%), the difference was statistically significant (P<0.05); the average number of lesions detected by MRI was more than that of CT. The average size of lesions detected was smaller than that of CT,the difference was statistically significant (P<0.05); the detection rate of MRI for lesions ≤5 mm was higher than that of CT (96.77% vs 18.82%),the difference was statistically significant (P<0.05); There was no statistically significant difference between MRI and CT in the detection rate of 6-10 mm and ≥11 mm lesions (P>0.05). Image features:MRI showed low signal on T1WI and high signal on T2WI. The shape of the lesions was mainly circular, elliptical, and cord; the shape of lesions below 5 mm was mostly spot-like, dot-like, and needle-like, and most lesions of 6-10 mm were oval. CT showed that the lesions showed low-density expression. In some patients, the cortex and white matter were unclear, and some showed the lenticular lens boundary, and the insular structure interface was not clear.Conclusion MRI had a higher detection rate of infarcts in different parts, and the number of detected lesions was larger, and the average size of the detected lesions was smaller. It was better than CT in the early diagnosis of acute cerebral infarction.
