Abstract

AbstractFollowing an IV injection of lmCi 99mTc – DTPA (Sn) 1.000 sec data are collected using a gamma camera and computer. Sixteen 60 sec frames are displayed on a Varian Statos grey-scale hard copy to give a qualitative dynamic display of renal uptake and excretion of chelate, and demonstrate the renal parenchyma and excretory system. Concurrent computer processing of the data produces combined uptake/excretion curves for both kidneys. Subsequently the glomerular filtration rate is measured using an external arm counting technique. Combining the results gives static and dynamic scintigrams of the renal parenchymal and collecting systems and a quantitative assessment of renal function.
