The standard technique of technetium 99m phosphate imaging is to perform a three phase study. All the following are the three phases described except (AIPG 2009)
|B||Immediate or equilibrium phase|
|D||Follow up phase|
Follow up phase
a. The standard technique of technetium 99m phosphate imaging is to perform a three phase study. The three phase bone scan consists of images taken in
b. Flow phase
c. The immediate or equilibrium phase and
d. The delayed phase. The flow phase is similar to a radionuclide angiogram in that it demonstrates the blood flow.
e. The equilibrium phase shows relative vascular flow and distribution of the radio isotope into the extracellular space.
f. The delayed phase image is obtained 2 to 4 hours after injection when renal excretion has eliminated most of the isotope except that taken up by osteoblastic activity.
