Bone scintigraphy seems to be the most frequently performed veterinary nuclear medicine procedure. Three-phase bone scintigraphy was conducted on three healthy dogs of either sex, aged between 5 and 6 years and three diseased dogs with bone disorders. The first phase was performed to detect any disparity in vascularity, second phase for inflammatory diseases of soft tissue and third phase to detect acute and chronic bone diseases.
The dose of Tc-MDP (Methylene diphosphonate) injected ranged 10–20 Mega Becquerel (MBq)/kg body wt. In the first phase, nuclear angiogram, dynamic images were acquired in 64x64 matrix for one-min (isec/frame). The second phase (tissue phase) study was conducted within 10 min post-injection as a static image in 256 x 256 matrix at 140 keV and 20% width. The third phase (delayed bone phase) was acquired in 256x256 matrix at 140 keV and 20% width two-to-three hr post-injection. All dogs included in the study were hydrated with 15 mL/kg 0.9% normal saline. All clinically abnormal cases were compared with three phases/contra lateral body parts.
