Abstract
The detection rate of renal masses has increased in the last decades owing to the widespread use of computed tomography.Early and accurate diagnosis and differential diagnosis are particularly important in the selection of appropriate treatment programs and improve patient survival which is an important basis for judging the prognosis. For many years, spiral computed tomography (CT) represented the modality of choice for assessment of tumor extension due to its high accuracy. With imaging technology in recent years, the constant development of multi-slice spiral CT (MSCT) upgrade, and a series of electron-beam CT image-processing, the technology used in CT perfusion imaging of renal tumors software successfully developed in clinical practice. Functional evaluation with CTp can play a major role, as changes in the perfusion occurs earlier following tissue kinase inhibitors before any actual change in size. This may potentially help in predicting prognosis, better selection of therapy and more accurate and better response evaluation in patients with RCC. The objective of this work was to evaluate the role of multidetector computed tomography perfusion as a useful tool in addition to multiphasic CT in renal masses characterization. This study included 83 patients with 85 renal masses, 57 male patients (68.6 %) and 26 female patients (31.4 %).Their ages ranged from 20 to 90 years with mean age of 54 year. The radiologic results for surgically operated and biopsied renal masses were correlated with the histopathologic results.
