title: Analysis on value of CT and MRI clinical application in diagnosis of middle-aged patients with multiple cerebral infarction.
abstract: OBJECTIVE
  To compare the application of MRI and CT imageological examination in diagnosis of middle-aged patients with multiple cerebral infarction.
  
  
  METHODS
  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.
  
  
  RESULTS
  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 24~72 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 24~72 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).
  
  
  CONCLUSIONS
  MRI has significant advantages in diagnosis of middle-aged patients with multiple cerebral infarction when compared to CT.
