Radiopharmacological agents and uses
- Tc-99m linked to methylene diphosphonate (99m Tc-MDP) is used in bone imaging
- Tc-99 pyrophosphate is used for defining hot spots in myocardial infarction/avid infarct imaging
- 99m Tc-Sc is used in imaging of reticuloendothelial system (liver/ spleen), gastric emptying, GI bleeds
- Gallium 67 is used for tumours/abscess
