In brief: Tc-99m-MDP Bone Scan

Bone scan often provides an earlier diagnosis and demonstrates more lesions than are found by radiographic procedures.
Tc-99m-mdp (methylene diphosphonate) is a bone seeking agent that concentrates in the mineral phase of bone. 2-3 hours after injection, 50%-60% of the activity localizing in bone and the remainder is cleared by the kidneys. F18-naf bone scans are done with pet cameras, r + expensive.

In brief: Whole body or PET-CT

Bone seeking radiopharmaceuticals distribute in proportion to local bone metabolism. Phosphate compounds labelled with technetium 99m are most commonly used.
A whole body image is obtained front and back while the patient lies flat on a long table. Flourine 18 can also be used with positron emission tomography volumetric imaging for more precise imaging in conjunction with ct.

In brief: Very simple

2 types of bone scans - (1) whole body bone scan (wbbs) & (2) three phase bone scan.
In either case you get an injection of a radioactive material and lay under a gamma camera for 45 min. And an image of your bone is produced. In wbbs (done for cancer metastases), you return 2 hours after injection. The 3-phase bone scan (done for infection), pictures are taken during & 15 min after injection.

In brief: Isotope injection

Radiotracer technetium 99m mehylene diphosphonate or similar agent is injected intravenously to be transported by blood stream to the bones.
Full skeletal deposition usually takes 2 to 3 hours. This agent goes where there is increased bone metabolism or repair of bone, such as fractures, tumors, arthritis, and infection. It detects subtle changes, sometimes not noticed on routine imaging.
