How does nuclear medicine do a bone scan?

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.
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.
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.
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.

Hi, I had a question. I recently had a whole body Nuclear Medicine bone scan done and the report says "Unremarkable tracer localization is seen in the osseous structures, what does this mean?

Bone scan. The fact that the interpreting md. stated it appears unremarkable is an indication that your scan is normal. The description about the distribution is the regular venacular describing the normal uptake by the bone ( osseous means our bony skeleton) of the material that has been injected . Read more...
