Purpose of review: Radionuclide renography has become standard practice but with controversial areas and variations in technique. This review looks at some recent studies to improve usefulness and to assess the current clinical indications for the use of dynamic radionuclide renography and considers some of the recent publications that have contributed to the subject during the past year.
Recent findings: Two important papers attempting to standardize the diuretic renogram and provide normal values for the MAG3 renogram are reviewed together with exercise renography in hypertension and used for the Captopril test.
Summary: Research into renography is not an active area at present but there have been a few important contributions which will improve the clinical value of radionuclide renography.
