Ultrasound continues to play the initial role in diagnosis and characterization of renal masses. Refinements in techniques of Multislice CT and MRI continue to improve image quality and detectability of renal masses. Conventional MR images potential advantages in preoperative evaluation is providing accurate data regarding their positions, local infiltrations, venous involvement, renal vascular anatomy, regional lymph nodes and distant metastases. Magnetic resonance diffusion imaging of the kidneys as a promising noninvasive technique for the assessment and characterization of different renal masses may replace other invasive techniques as biopsy and may stop unnecessary nephrectomy for benign renal lesions ER -
