Renal Cortical Scarring: 68Ga-PSMA-11 PET Versus 99mTc-DMSA Scanning in a Case of Pyelonephritis

Abstract

We previously reported the 68Ga-labeled prostate-specific membrane antigen (PSMA)-11 and 99mTc-dimercaptosuccinic acid (DMSA) images of the first patient in our prospective research comparing renal 68Ga-PSMA-11 PET with 99mTc-DMSA scanning in adults with pyelonephritis. Here, we present the renal cortical 68Ga-PSMA-11 PET and 99mTc-DMSA images of our second patient, who had chronic recurring pyelonephritis and demonstrated renal parenchymal defects secondary to scarring in the kidney.

Keywords: 68Ga-PSMA-11; DMSA scan; PET; pyelonephritis; renal scar.
