CT is the most commonly used modality for the detection and characterization of renal masses as well as presurgical planning and post-therapy surveillance. Check before giving contrast. 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 .

In the setting of advanced RCCs, tumor extension into the renal vain or inferior vena cava may be best assessed on the nephrographic phase as well. Obtained at 100 seconds to 120seconds after IV contrast injection, the timing for this contrast-enhancement phase is later than the typical portal venous phase, allowing for uniform enhancement of the renal parenchyma and in general providing the highest tumor to background distinction compared with the other phases ( Fig. For example, a tumor with enhancement features that suggest a papillary RCC can be confirmed with percutaneous biopsy.

Pregnancy (risk vs benefit ratio to be assessed) 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. The excretory phase may be helpful for distinguishing urothelial cancers from RCCs and parapelvic or peripelvic cysts from hydronephrosis and for diagnosing calyceal diverticula. Excretory phase is obtained at 7 minutes to 10minutes after IV contrast injection. Not all exams are available at all locations. , Suggested IV contrast type by the SAR DFP is low-osmolar or iso-osmolar contrast material, at a dose of 35 g to 52.5g iodine equivalent (ie, for contrast material that contains 350mg of iodine/mL, the corresponding dose is 100150mL), or weight-based dosing. Check before giving contrast.

If possible provide a chaperone for claustrophobic patients (e.g. Prednisone: 50 mg PO (three doses total) to be taken 13 hours, 7 hours and 1 hour prior to appointment. MR imaging protocols should take advantage of the improved soft tissue contrast for renal tumor diagnosis and staging.
