Defining Renal Anatomy and Function with 99m Technetium Dimercaptosuccinic Acid: Clinical and Renographic Correlation

Abstract
Renal anatomy and function with 99mTc-dimercaptosuccinic acid and 131I-hippuran were studied in 17 patients with suspected unilateral renal disease. 99mTc-dimercaptosuccinic acid gave excellent images of cortical anatomy; there was close correlation of its relative uptake with relative function determined by 131I-hippuran renography. The morphologic and functional data obtained with 99mTc-dimercaptosuccinic acid have potential clinical utility, especially when nephrectomy is being considered.
