Tc-99m sestamibi single-photon emission computed tomography (SPECT)/CT has been shown in several studies to be helpful when the diagnosis of a renal oncocytoma is suspected [21-23]. For example, in a study of 31 renal masses imaged with Tc-99m sestamibi SPECT/CT, 91.6% (11 of 12) of oncocytomas had radiotracer uptake above aUniversity of California San Francisco School of Medicine, San Francisco, California. bPanel Chair, Northwestern University, Chicago, Illinois. cPanel Vice- Chair, UT Southwestern Medical Center, Dallas, Texas. dUniversity of Rochester Medical Center, Rochester, New York. eThe University of Texas MD Anderson Cancer Center, Houston, Texas. fUniversity of Pennsylvania School of Medicine, Philadelphia, Pennsylvania; American Society of Nephrology. gUniversity of Washington, Seattle, Washington; American Urological Association. hDuke University Medical Center, Durham, North Carolina. iMayo Clinic, Rochester, Minnesota. jEmory University School of Medicine, Atlanta, Georgia. kThomas Jefferson University Hospital, Philadelphia, Pennsylvania. lCleveland Clinic, Cleveland, Ohio. mMedical University of South Carolina, Charleston, South Carolina; American Urological Association. nUniversity of Alabama at Birmingham, Birmingham, Alabama. oJohns Hopkins University School of Medicine, Washington, District of Columbia. pUniversity of Maryland School of Medicine, Baltimore, Maryland. qSpecialty Chair, University of Alabama at Birmingham, Birmingham, Alabama.
