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

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

Automated summary

This study compared the images of adult patients with pyelonephritis using different radiolabeled agents for PET and scanning to evaluate their diagnostic application. The images of the second patient demonstrated renal parenchymal defects secondary to scarring in the kidney.
