Abstract

The introduction of multiphase helical computed tomography has created many important advances in the detection and characterisation of renal masses. Renal cell carcinoma (RCC) is the seventh most common cancer and makes up 80-85% of all primary renal cancer in adults. If it is found and treated early, the chances of survival from kidney cancer are high. This cross-sectional comparative was carried out at department of CMH/MH Rawalpindi from 1st February 2007 to 25 March 2008 to evaluate accuracy of multiphase helical tomography in detection and characterisation of suspected renal masses using histopathological findings as gold standard. Thirty patients with suspicion of having renal masses were scanned with multiphase CT scanning and 5 mm thick contiguous section were obtained from kidneys before and after injection of intravenous contrast material. The corticomedullary phase images were obtained after a delay of 25 seconds and nephrographic phase images, after a delay of 120 seconds after initiation of contrast medium injection. The numbers of lesions detected in all three phases were determined. The mass was then characterised by evaluation of its features and by its degree of contrast enhancement. Results of CT scan were co...Continue Reading
