The Usefulness of 99m Tc Diethylenetriamine Pentaacetate (DTPA) or Mercaptoacetyltriglycine (MAG3) Renal Perfusion Scan in Assessing Chronic Renal Complications of COVID-19

Background: Imaging departments worldwide are exploring different ways to help manage chronic complications of COVID-19 after two years. Objectives: Renal complications following acute kidney injury in the acute phase of COVID-19 or exacerbation of chronic kidney disease (CKD) are crucial. Methods: This article presented the role of 99m Tc diethylenetriamine pentaacetate (DTPA) or mercaptoacetyltriglycine (MAG3) renal perfusion scan in managing chronic renal complications following COVID-19 by submitting the relevant techniques and available radiopharmaceuticals. Results: Renal perfusion scan with 99m Tc DTPA and MAG3 could evaluate profusion and function in acute and chronic settings and manage these renal complications. Conclusions: Based on the results, 99m Tc DTPA or MAG3 renal perfusion scan could detect, monitor, and evaluate response to treatment in COVID-19-related renal chronic damages and complications.
