Abstract:
Purpose To analyze the 64-row spiral CT manifestations and evaluate the diagnostic value in early primary ureteral carcinoma.Materials and Methods Fifteen cases of early primary ureteral carcinoma proved by surgery and pathology were reviewd.Unenhanced scan,enhanced scan in arterial phase,parenchymal phase,delayed phase and CPR construction were performed in all patients.MIP were performed in 10 cases.Results ① the localization of lesions:7cases were located at the right ureter and 8 cases at the left.2 cases were located at the upper portion of the ureter,6 at mid portion,and 7 at lower portion;② CT manifestations:8 cases showed irregular thickened wall and central lumen stenosis,4 cases eccentric soft tissue mass in lumen and crescent or linear vestigial lumen,3 cases soft tissue density and obsolescent lumen;③the enhanced features:the tumor was demonstrated apparent and uniform enhancement in 13 cases,inhomogeneous enhancement in 2 cases after administration of contrast medium;④ the accompanied signs:proximate renal and ureteral presented distention,dropsy in different degrees,5 cases appeared delayed development.Conclusion 64-row spiral CT volume scan and 3D reconstruction with multiplane and multiorientation,combined with axial enhanced scan,can show lesions dimensionly and increase the dignostic accuracy in early primary ureteral carcinoma,which has an important value.
