Objective To explore the application value of multi-slice spiral CT in the clinical diagnosis of aortic dissection. Methods 40 patients with aortic dissection who came to our hospital for treatment from March 2021 to March 2022 were randomly selected as the study subjects. All patients were performed plain and enhanced CT scans after admission. The multi-slice spiral CT status of patients with aortic dissection was analyzed. At the same time, the plain and enhanced CT scans of the two groups of patients and the display status of endometrial rupture, endometrial valve and true and false lumen after treatment were analyzed. Results Among the 40 selected patients, 13 were Debakey Ⅰ, 4 were Debakey Ⅱ, 10 were Debakey Ⅲ and 13 were Debakey Ⅲ B. According to the scanning results, the display rate of MPR reached 95% (38/40) in the display of intimal rupture. Compared with CT enhancement, VR and CT plain scan, the display rate was significantly higher, with a significant difference (P<0.05); The display rate of MPR and CT enhanced scan was 100%, significantly higher than that of CT plain scan and VR, with significant difference (P<0.05). In the display of true and false cavities, the display rate of MPR and CT enhanced scan was 100%, and the display rate of VR was 92.5% (32/40), and the three were significantly higher than that of CT plain scan, with significant difference (P<0.05). Conclusion The application of multi-slice CT in the diagnosis of aortic dissection can clearly show intimal rupture, intimal valve and true and false lumen, thus improving the accuracy of classification, and has high clinical application value.
