Na[ 99m Tc]TcO 4 is used in the dual-tracer method as it is taken up by functioning thyroid cells. The Na[ 99m Tc]TcO 4 image is subtracted from the [ 99m Tc]Tc-MIBI / [ 99m Tc]Tc-tetrofosmin image, thus revealing hyperfunctioning parathyroid glands.

WebJan 1, 1994 · Like alcohol intoxication levels, levels of exposure to radioactivity (due to radioactivity deposited in the body) depend on a person's weight. A diagnostic tracer of one microcurie of radioactive calcium 45, given orally, would result in an exposure of 3.7 millirems for a 100-pound person, and half of that, 1.85 millirems, for a 200-pound person. WebThe tracer is radiolabeled, meaning it emits gamma rays that are detected by the PET scanner. The computer collects the information emitted by the tracer and displays it on the CT cross-sections. The radioisotopes used in PET to label tracers are 11C, 13N, 150, and 18F (carbon, nitrogen, oxygen and 18F used as a substitute for hydrogen).
