Abstract

   

Background and Objectives: The Introduction of Helical CT is one of many recent advances which create improvement in the detection and characterization of renal masses and compare the enhancement of renal mass and cortex and to evaluate the enhancement of renal veins and inferior vena cava during corticomedullary and nephrographic phase.

Methods: Study included 33 cases of renal masses was done for a period of 1 year from Nov 2018 to November 2019 in the department. Patients were evaluated thoroughly.

Results and Conclusions: For the final analysis thirty two patients were included (19 males and 13 females). Thirty three lesions were detected in thirty two patients. Of these, thirty lesions were neoplastic lesions of which majority of the neoplastic lesion comprised of Renal cell carcinoma (22 cases), Transitional cell carcinoma (3 cases), Angiomyolipoma (1 case), Renal oncocytoma (1 case), Renal metastasis (1 case), Renal abscess (1 case) and three lesions were cystic lesions.

  1. Renal neoplasm showed greater enhancement in the nephrographic phase compared with that in corticomedullary phase (p=.001).
  2. Renal cortex also showed greater enhancement in the nephrographic phase compared with that in corticomedullary phase (p=.001).

Renal vein are best visualized in corticomedullary phase and inferior vena cava is better visualized in nephrographic phase.
