The aim of our study was to assess i The aim of our study was to assess if quantitative multiphasic multidetector computed tomography MDCT enhancement patterns of renal masses malignant and benign may be useful to enable lesion differentiation by their enhancement characteristics.

We studied attenuation values using the values within the most avidly enhancing portion of the tumor 2D analysis and within the whole tumor volume 3D analysis. A region of interest ROI was also placed in the adjacent uninvolved renal cortex to calculate the relative tumor enhancement ratio.

Results: Significant differences were noted in enhancement and de-enhancement diminution of attenuation measurements between the postcontrast phases values by histology. The highest areas under the receiver operating characteristic curves AUCs of 0.

Wash-out values proved useful only for discrimination between ccRCC and oncocytoma Conclusions: Our observations point out that imaging features may contribute to providing prognostic information helpful in the management strategy of renal masses.
