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).
Nuclear imaging is, in a sense, radiology done inside out, because it records radiation emitted from within the body rather than radiation that is transmitted through the body from external sources like X-ray generators. In addition, nuclear medicine scans differ from radiology, as the emphasis is not on imaging anatomy, but on the function.
It can show particular tissues more clearly than CT.; [4] video link: Linear accelerator: used in radiotherapy for cancer: Functional magnetic resonance imaging (fMRI) video link: Positron emission tomography (PET Scan) video link: Radio-isotope scan or nuclear scintigraphy: These radioactive compounds are administered so that specific tissues ...
Scintigraphy (from Latin scintilla, "spark"), also known as a gamma scan, is a diagnostic test in nuclear medicine, where radioisotopes attached to drugs that travel to a specific organ or tissue (radiopharmaceuticals) are taken internally and the emitted gamma radiation is captured by gamma cameras, which are external detectors that form two-dimensional images [1] in a process similar to the ...
These scanners could scan the body in 2–5 seconds, thereby eliminating motion artifacts due to breathing. The HPS 1440 scanner was introduced in 1985 as an ultra high resolution CT scanner. These scanners were of the fourth generation design, in which there was a stationary ring of detectors and the x-ray tube rotating inside the detector ring.

A DPD scan is a type of nuclear medicine imaging test which uses radioactive technetium-99m (99m Tc) and 3,3-diphosphono-1,2-propanodicarboxylic acid (DPD) to diagnose cardiac amyloidosis. The radiopharmaceutical is taken up only in patients with ATTR amyloidosis , making it a useful tool to differentiate from AL amyloidosis .
In the nuclear power sector, the SPECT technique can be applied to image radioisotope distributions in irradiated nuclear fuels. [7] Due to the irradiation of nuclear fuel (e.g. uranium) with neutrons in a nuclear reactor, a wide array of gamma-emitting radionuclides are naturally produced in the fuel, such as fission products ( cesium-137 ...
