Correlation and comparison of CT Urography and non contrast MR Urography in evaluation of malignant urinary tract lesions- A study of 54 patients

Abstract

Background: Now a day with wider availability of multislice CT scanner and modern MR machines, it is possible to characterize various malignant urinary tract lesions with greater details on imaging. Aims and objective : To characterize various malignant urinary tract lesions on the basis of their location, internal characteristics, adjacent and distant spread and histopathological correlation on imaging by CT Urography and non contrast MR Urography and to compare the results by these two modalities. Material and Method: Selected patients underwent CT urography in 16 slice CT scan machine and non contrast MR urography in 1.5 T 16 channel MRI machine. Results: Kidney is most commonly involved organ by malignant lesions in urinary tract with renal cell carcinoma is frequently observed malignancy. CT Urography is better modality for internal characterization and adjacent vascular spread of malignant lesion than non-contrast MR Urography. Conclusion: For internal characterization and spread of malignant urinary tract lesions, CT Urography is better modality than non-contrast MR Urography. Key words: CT Urography, non contrast MR Urography, malignant lesions, urinary tract.
