MR imaging serves as a problem-solving tool in renal mass evaluation, and MR imaging protocols should take advantage of its multiparametric capability to provide additional information for renal mass characterization. Renal masses usually are discovered incidentally on either a noncontrast-enhanced or a single-phase postcontrast CT obtained for unrelated indications. The field of view, whether restricted to the kidneys themselves or expanded to include from the diaphragm to the iliac crest, also depends on the clinical questions. Scanner preference: 1.5T Unable to process the form.

Nephrographic and excretory phases also are included, with the field of view expanded from diaphragm to iliac crest. Given the indolent nature of papillary RCCs in general, these may be appropriate for active surveillance rather than surgical resection, especially in patients who are poor surgical candidates. Many institutions will perform this around 5 minutes to demonstrate opacification of the ureters, mid-diaphragm to the iliac crest (covering kidneys), mid-diaphragm to the iliac crest (covering kidneys), contrast injection considerations (bolus tracking), level of the diaphragmatic hiatus or first lumbar vertebra at the aorta, 100 mL of non-ionic contrastat 3 to 5 mL/s (a higher flow rate will equal greater enhancement), 20-30 seconds post bolus trigger (30-40 s after injection), mid-diagram to lesser trochanter (covering entire renal system), pseudoenhancement, an artifact encountered where the calculated density of a lesion is inaccurately increased, is a problem often noted in renal mass scans,dual-energy CT via virtual monoenergetic images at a KeV range of 80 Kev to 90 KeV can minimize beam hardeningand partial volumingand overcome this issue, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys.

Computed tomography (CT) protocols for renal mass evaluation should be tailored to the clinical indications with careful considerations of balancing diagnostic accuracy and radiation dose.
