Abstract：Objective To analyze the diagnostic value of multi-slice spiral CT ( MSCT) and transthoracic echocardiography ( TTE) in the diagnosis of congenital aortic dysplasia, so as to improve the imaging examination in the application for this disor-der.Methods The clinical data of 26 patients with congenital aortic dysplasia, who underwent MSCT and TTE examination, were retrospectively analyzed, aiming at studying the imaging characteristics of this disease.Results In those selected patients, there were 10 cases of the coarctation of aortic arch 4 cases of the interruption of aortic arch.9 cases were right aortic arch,2 cases were double aortic arch, and 1 case was abdominal aorta.Among them, 24 cases were positively diagnosed by MSCT, with the di-agnostic accuracy of 92.3%, 2 cases were, with the misdiagnosis rate of 7.7%;22 cases were positively diagnosed, with accura-cy rate of 84.6%, 4 cases were misdiagnosed, with misdiagnosis rate of 15.4%.Conclusion With respect to the imaging diag-nosis of congenital aortic dysplasia, MSCT or TTE each has advantages and disadvantages.The combined use of two kinds of in-spection can provide clinicians with more accurate imaging information for in the diagnosis of the disease.
