Role of nuclear medicine in evaluation of renal system

The aim of this article is to highlight the importance of Nuclear Medicine imaging in the diagnosis and management of common renal conditions. Nuclear Medicine procedures provide useful information on renal blood flow and individual kidney functions and drainage. The advantages of these procedures are that there is low radiation burden, no sedation or no special pre-procedural preparations are required and are easy to perform and interpret. It is a valuable asset in the imaging of renal system in both adults and children. Renal radiopharmaceuticals are categorized by their uptake and clearance mechanisms for studying glomerular filtration, tubular secretion, or cortical binding.
