To compare the application of MRI and CT imageological examination in diagnosis of middle-aged patients with multiple cerebral infarction.
218 cases of patients with multiple cerebral infarction were selected for CT and MRI examinations, and the clinical value of CT and MRI examinations in diagnosis and imaging of middle-aged patients with multiple cerebral infarction was compared and analyzed.
For the 218 cases of patients, the total detection rate of CT examination was 56.88% and that of MRI examination was 95.87%, indicating a statistically significant difference (x (2)=6.795, P=0.008). For the 85 patients in the group of less than 24 h, the detection rate of CT examination was 37.65% and that of MRI examination was 94.12%, and the comparative analysis between two groups suggested a statistically significant difference (x (2)=6.357, P=0.006); for the 70 cases in the group of 2472 h, the detection rate of CT examination was 48.57%, and that of MRI examination was 97.14%, suggesting a statistically significant difference (x (2)=5.315, P=0.026); for the 63 cases in the group of greater than 72 h, the detection rate of CT and MRI examinations showed no statistically significant difference (P>0.05). This showed that the cerebral infarction detection rate of MRI examination was significantly higher than that of CT examination in the group of less than 24 h and the group of 2472 h, while the difference in the cerebral infarction detection rate was not significant in the group of greater than 72 h. The number of lesions detected by MRI examination was significantly higher than that by CT examination (P<0.01); the capability of MRI examination to detect small lesions of cerebral infarction was significantly stronger than that of CT examination (P<0.05).
MRI has significant advantages in diagnosis of middle-aged patients with multiple cerebral infarction when compared to CT.
比较MRI与CT影像学检查在中年多发性脑梗死患者诊断中的应用。
选取218例多发性脑梗死患者进行CT和MRI检查，对比分析CT和MRI检查在中年多发性脑梗死患者诊断及成像中的临床价值。
218例患者中，CT检查总检出率为56.88%，MRI检查总检出率为95.87%，差异有统计学意义（x²=6.795，P=0.008）。在发病时间小于24 h的85例患者中，CT检查检出率为37.65%，MRI检查检出率为94.12%，两组比较差异有统计学意义（x²=6.357，P=0.006）；在发病时间2472 h的70例患者中，CT检查检出率为48.57%，MRI检查检出率为97.14%，差异有统计学意义（x²=5.315，P=0.026）；在发病时间大于72 h的63例患者中，CT与MRI检查检出率差异无统计学意义（P>0.05）。这表明在发病时间小于24 h及2472 h组中，MRI检查对脑梗死的检出率明显高于CT检查，而在发病时间大于72 h组中，脑梗死检出率差异不明显。MRI检查发现的病灶数明显多于CT检查（P<0.01）；MRI检查对脑梗死小病灶的检出能力明显强于CT检查（P<0.05）。
与CT相比，MRI在中年多发性脑梗死患者的诊断中具有显著优势。
