title: A dose-attenuation shield for use in glomerular filtration rate computations. A method for combined renal scintiangiography and functional quantification.
abstract: Renal perfusion and function can be determined by renography using Tc-99m DTPA. However, the high dose of tracer necessary for scintiangiography may result in inaccurate syringe-count determinations when measured by the gamma camera necessary for calculating the glomerular filtration rate by a camera technique. This report describes a syringe shield, constructed at minimal cost, which allows for suitable count attenuation and use of high doses of tracer for assessment of both renal perfusion and function.
