Technetium 99 Bone Scan: Reasons, Procedure

The most common radiopharmaceutical for bone scintigraphy is Tc with methylene diphosphonate (MDP). Other bone radiopharmaceuticals include Tc with HDP, HMDP and DPD. MDP adsorbs onto the crystalline hydroxyapatite mineral of bone. Mineralisation occurs at osteoblasts, representing sites of bone growth, where MDP (and other diphosphates) "bind to the hydroxyapatite crystals in proportion to local blood flow and osteoblastic activity and are therefore markers of bone turnove… WebbIn the staging of neuroblastoma, 99m Tc-MDP bone scintigraphy does not identify unique sites of disease that affect disease stage or clinical management, and in the majority of cases bone scans can be omitted from …
