- Information in this record refers to the use of technetium Tc 99m disofenin (Tc 99m DISIDA) as a diagnostic agent. (nih.gov)
- 1 ] The effective half-life of Tc 99m DISIDA ranges from 3.6 to 3.8 hours. (nih.gov)
- 1] Other experts state that breastfeeding need not be interrupted after administration of technetium Tc 99m exametazime in doses up to 500 MBq (15 mCi) to a nursing mother. (nih.gov)
- For white blood cells labeled with technetium Tc 99m exametazime 180 to 400 MBq, the International Atomic Energy Agency recommends that breastfeeding should be interrupted for 12 hours. (nih.gov)
- Hence, in view of the above applications this mass attenuation coefficient is estimated by WinXCom program which is the successor of program Xcom for the technetiumā99m compounds such as mebrofenin, disofenin, lidofenin, bisicate, and exametazime for the photon energy range from 8 to 32 keV. (tanjit.net)
- Tc 99m is a gamma emitter with a principal photon energy of 140 keV and a physical half-life of 6.04 hours. (nih.gov)
- For nursing mothers who work with Tc 99m substances in their workplace, there is no need to take any precautions other than those appropriate for general radiation protection. (nih.gov)
