Significance of magnetic resonance imaging combined with computed tomography in the diagnosis of patients with cerebral infarction

Abstract

Objective To investigate the significance of magnetic resonance imaging(MRI) combined with computed tomography(CT) in the diagnosis of patients with cerebral infarction. Methods A total of 85 cases of cerebral infarction in General Hospital of Datong Coal Group from April 2015 to November 2017 were selected as subjects and were examined by MRI and CT. The detection rate of combination of the two methods for cerebral infarction in different infarction onset time, different infarctions location and different volumes of infarction focus were statistically compared. Results ①Among those 85 cases of cerebral infarction, there were 85 lesions, including 61 lesions defined by CT, 66 lesions defined by MRI, and 82 lesions defined by the combined of those two methods. The total lesion detection rate of combined detection (96.47%) was higher than that of CT (71.76%) and MRI (77.64%) examination separately(P 72 h among the combined detection (95.00%) and CT (75.00%) and MRI (85.00%, P>0.05). ③The combination detection rate in lesions≤2 mm (91.17%) was higher than CT (52.94%) and MRI (64.70%) examination alone (P 2 mm among the combined detection (94.11%) and CT (84.31%) and MRI (90.19%, P>0.05). Conclusions MRI combined with CT has high diagnostic value for patients with cerebral infarction, especially for the disease with onset time< 24 h, between 24-72 h and lesions≤2 mm, which can provide guidance for clinical treatment.
