Abstract:
Objective To assess the application of spiral CT angiography in the diagnosis of Takayasu arteritis.Methods Vascular imaging features of three-dimensional CT angiography of 56 patients with Takayasu arteritis were analyzed retrospectively.Results The vascular imaging of all the patients were qualified for diagnosis.A total of 175 arteries were involved,including subclavian arteries (36.00%,63/175) with a high percentage of the left subclavian arteries (24.00%,42/175) ,common carotid arteries (29.71%,52/175) and renal arteries (10.86%,19/175) .The affected artery wall had varying degrees of concentric or eccentric thickening,and stenosis or occlusion of lumen was observed.Conclusion Threedimensional spiral CT angiography can make clear diagnosis of Takayasu arteritis,including the scope,extent and nature,and thus is worthy of clinical application.
