PDFAbstract
Objective To evaluate the diagnostic value of primary ureteral carcinoma with magnetic resonance imaging (MRI). Methods Eleven pathologically confirmed patients with primary ureteral carcinoma were recruited and examined by MRI. Results The MRI images of all 11 patients appeared occupying lesion signals of abnormal ureteral obstruction with hydrosalpinx and hydronephrosis of affected side. The lesion demonstrated slightly low signal or equisignal on Toumor T1WI, and slightly high signal on T2WI; the signals were improved moderately or greatly with enhanced scan. Conclusion MRI combined with MRU and enhanced scan could fully confirm the site, feature, size and enhancement of ureteral carcinoma, and change of surrounding tissues; and play an important role of the diagnosis and differential diagnosis of ureteral carcinoma.
