SIR-Spheres Study to Calculate the Radiation-Absorbed Dose of 99mTc-MAA

The goal of this interventional clinical trial is to evaluate the dose of radiation of Technetium-99m macroaggregated-albumin (99mTc-MAA) after an intra-arterial injection to the whole body and non-liver critical organs in patients who are undergoing evaluation for SIR-Spheres treatment for hepatocellular carcinoma.

Treatment and study plan

99mTc-Macro Albumin Aggregate

Drug

Technetium-99m macroaggregated-albumin consists of macroaggregated-albumin particles labeled with technetium-99m (99mTc), with a size between 10 and 90 microns in diameter. 99mTc is a gamma emitting radioactive isotope commonly used for diagnostic localization studies.
