4. Introduction to BONE SCAN-1
• BONE SCAN is one of the most commonly
performed nuclear medicine procedure
world wide.
• Its very feasible and cost effective way of
scanning whole of the skeleton with single
injection at very low cost financially and
lower radiation exposure burden.

5. Introduction to BONE SCAN-2
• Very important fact while
referring for bone scan and
interpreting the bone scan is…
HIGH SENSITIVITY
LOW SPECIFICITY

6. Introduction to BONE SCAN-3
• Various chemical agents have been used
for bone scan and Technetium 99m
labeled MDP is agent of choice these days
• The mechanism of localization of Tc99m-
MDP is dependant on blood flow and
adsorption of agent on hydroxy-appatite of
the bones
