Abstract Objective: To evaluate the diagnostic effect and characteric of MSCT urography in ureteric carcinoma. Materials and Methods: To analyse the MSCT features in 18 cases of ureteric carcinomas confirmed by pathology. Conventional scan and contrast enhanced scan including arterial phase, venous phase multiple-delay-phase scan were performed in all cases. The reconstruction methods such as MPR, CPR, VR, MIP were performed. Results: Axial images of arterial and venous phases together with MPR, CPR show the relationship between the tumor and its tissues around it clearly, especially CPR, it can well and continually show the whole ureter and the tumor through the contrast of urine and contrast medium, VR and MIP reconstruction are also good in showing the irregular stenosis and obstruction by the tumor. Conclusion: MSCT urography shows the ureteric carcinoma clearly from multiple planar, multiple directions . It offers a good method to clinical treatments.
