Such information can be helpful in guiding patient management. For example, renal masses that are homogeneous and have Hounsfield units (HU) measuring fluid density (between 10 HU and 20 HU) on noncontrast-enhanced CT are benign simple cysts. Computed tomography (CT) and MR imaging are mainstays for renal mass characterization, presurgical planning of renal tumors, and surveillance after surgery or systemic therapy for advanced renal cell carcinomas.

Arterial phase (approximately 30-second delay) with field of view focused on the kidneys is recommended to better depict arteries and their relationship to the renal tumor. With increasing utilization of cross-sectional imaging such as ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI), the detection rates of an incidental kidney lesion have increased over time [].While most incidental kidney lesions can be left alone as they will have no clinical consequences, some are pathologies (eg, renal cell carcinoma, renal . Imaging is essential in renal mass characterization in order to guide appropriate treatment selections, because the management paradigm of localized renal tumors has evolved in recent years to include active surveillance and thermal ablation in addition to partial and radical nephrectomy.
