Abstract：Objective To compare the diagnostic sensitivity of pulse gated non enhanced fast MR imaging in different types of aortic dissecting aneurysm.Methods From January 2010 to April 2017,24 cases of aortic dissection admitted in our hospital for diagnosis and treatment were selected as the research object and were divided 10 cases of type A and 14 cases of type by the intraoperative pathological diagnosis.The quality and characteristics of pals-gated non enhanced fast MR imaging in all the patient were recorded,and the differential diagnosis sensitivity were determined.Results The pulse-gated non-enhanced fast MR imaging in the patients with type A and type B aortic dissection were all satisfied the clinical diagnosis,and the image quality of valve junction,aortic sinus and coronary artery opening were all grade 2 and grade 1.The pulse gated non enhanced fast MR imaging in the differential diagnosis of sensitivity and specificity for different types of aortic aneurysm were 100％ and 90％;and the accuracy evaluation of mitral valve junction,aortic sinus,coronary artery were 91.7％,87.5％ and 87.5％.Conclusion Pulse-gated non-enhanced fast MR imaging in different types of aortic dissection are with excellent sensitivity and high feasibility,it can effectively display morphological information,so as to guide the clinical diagnosis.
