Abstract:
Objective To compare the clinical value of two kinds of imaging methods including CT and MRI in early diagnosis of acute multiple cerebral infarction. Methods The imaging data of CT and MRI of 108 patients with acute multiple cerebral infarction were analyzed. The total detection rate, the detection rate in different time periods,the number and area of detected lesions and the inspection time of CT and MRI in early diagnosis of acute multiple cerebral infarction were compared. Results The total detection rates of patients with acute multiple cerebral infarction by CT and MRI were 57. 41%,96. 30%,respectively. The total detection rate of MRI was significantly higher than CT(χ2 =9. 73,P<0. 05). The detection rates of patients with acute multiple cerebral infarction for onset within 24h and 24-72h by MRI were significantly higher than CT(χ2 =18. 54,16. 20,all P<0. 05). There was no significant difference in detection rate of patients with acute multiple cerebral infarction for onset >72h between CT and MRI(P>0. 05). The number of detected lesions of patients with acute multiple cerebral infarction by MRI was significantly more than CT(t=2. 39,P<0. 05). The area of detected lesions and the inspection time of patients with acute multiple cerebral infarction by MRI were significantly less than that by CT(t =2. 43,2. 60,all P <0. 05). Conclusion Compared with CT, MRI in the early diagnosis of acute multiple cerebral infarction can effectively improve the detection rate in early stage, avoid the missed diagnosis of small lesions and is helpful to shorten the examination time.
