Urinary excretion of /sup 99m/Tc administered as microspheres

Journal Article · · Radiology; (United States)
OSTI ID:5220007
/sup 99m/Tc-albumin microspheres were administered intravenously and urinary radioactivity was determined for various period up to 25 hours. The average accumulated urinary level was 0.68% of the injected dose at 1 hour and 18.6% at 24 hours. The average bladder wall dose was 101.98 mrad (1019.79 ..mu..Gy) based on an administered dose of 3 mCi (111 MBq). While the chemical state of the excreted /sup 99m/Tc was primarily free pertechnetate, some reduced /sup 99m/Tc species were also excreted. The appearance of /sup 99m/Tc in the kidneys within the first 15 minutes following injection should not be considered unusual, nor necessarily indicative of right-to-left shunting.
