A bone scan or bone scintigraphy / s ɪ n ˈ t ɪ ɡ r ə f i / is a nuclear medicine imaging technique used to help diagnose and assess different bone diseases. These include cancer of the bone or metastasis, location of bone inflammation and fractures (that may not be visible in traditional X-ray images), and bone infection (osteomyelitis). [1]
Its complex with radioactive technetium, 99m Tc medronic acid, is used in nuclear medicine to detect bone abnormalities, including metastases. References
A renogram, which may also be known as a MAG3 scan, allows a nuclear medicine physician or a radiologist to visualize the kidneys and learn more about how they are functioning. [1] MAG3 is an acronym for mercapto acetyl tri glycine , a compound that is chelated with a radioactive element – technetium-99m .
Technetium (99m Tc) medronic acid is a pharmaceutical product used in nuclear medicine to localize bone metastases [1] as well as other diseases that can alter the natural turn-over in the bone by bone scintigraphy.
The technetium-99m radioisotope is used predominantly in bone and brain scans. For bone scans , the pertechnetate ion is used directly, as it is taken up by osteoblasts attempting to heal a skeletal injury, or (in some cases) as a reaction of these cells to a tumor (either primary or metastatic) in the bone.
The common bone scan with 600 MBq of technetium-99m MDP has an effective dose of approximately 2.9 mSv (2,900 μSv). [24] Formerly, units of measurement were: the curie (Ci), equal to 3.7 × 10 10 Bq, and also equal to 1.0 grams of radium ; the rad (radiation absorbed dose), now replaced by the gray; and

The most common isotope used in diagnostic scans is Technetium-99m, used in approximately 85% of all nuclear medicine diagnostic scans worldwide. It is used for diagnoses involving a large range of body parts and diseases such as cancers and neurological problems. [ 1 ]
