Introduction. Bone scintigraphy is one of the commonly performed nuclear medicine procedures. Technetium 99m-methyl diphosphonate (Tc-99m MDP) is an ideal bone scintigraphy agent due to its high bone-to-soft tissue uptake, rapid blood clearance, and good in-vivo stability.[1,2,3] Tc-99m MDP is chemisorbed on the bone tissue based …
