Evaluation of renal function parameters with simultaneously administered 99mTc-DTPA and 131I-hippuran
The present study aimed at comparing two renal function tests using 99mTc-DTPA (diethylene triamine penta acetic acid) and 131I-labeled hippuran (o-hippuric acid). A mixture of 80 Mbq 99mTc-DTPA and 7.4 MBq 131I-hippuran in a total volume of 1.5 ml or less was injected into an arm-vein. Both radiopharmaceuticals have identical intitial distributions in the blood pool when injected in this manner.
