PET/MR for Characterization of Renal Masses (RMs)

The frequency of kidney tumors found incidentally on imaging studies performed for unrelated reasons continues to increase leading to more surgeries and ablations for the treatment of renal masses thought to be cancer. However, about 20% of these masses are not cancerous and do not require treatment. Many cancerous kidney tumors are indolent and can be followed safely with imaging (i.e., particularly tumors \<2 cm and in patients with limited life expectancy), while some tumors are both malignant and aggressive, with a higher potential to spread outside the kidney and require treatment. The purpose of this observational study is to assess the ability of Fludeoxyglucose (18F) (FDG) PET/MR to distinguish different types of kidney tumors. The investigators hypothesize that PET/MR will better show differences between aggressive and both indolent and benign kidney masses compared to the currently used radiologic scans. Participants will be selected from those who have been scheduled to receive a contrast-enhanced MRI for their regular care due to a suspicious kidney mass. Participants will have their MRI on a hybrid PET/MR scanner capable of obtaining both MRI and PET images. While they are receiving their standard of care MRI exam, patients will also receive a research FDG PET exam. Participants will have an IV placed for administration of the MRI contrast agent, just as they would if they were not taking part in the study. The same IV will be used to give the FDG radiopharmace…
