Figure 8c. 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 external detectors (gamma cameras) to form two-dimensional images in a similar process to the capture of x . It then takes some time - sometimes several hours (depending on what is being scanned) - for the radionuclide to travel to the target organ or tissue, and to be 'taken' into the active cells. Viewer. Guidelines provided by the Society of Nuclear Medicine 1 and the American College of Radiology 2 are exhaustive with regard to indications and medicines/substances to avoid with thyroid scans.

Spondylolysis, a condition caused by a defect in the pars interarticularis of a vertebra, is an important cause of pain in active young adults. In testicular torsion, there is decreased or absent uptake of radionuclide, while uptake is increased in cases of epididymoorchitis. Radiotracer accumulation in both the vertebral body and pedicles usually indicates metastatic disease, whereas abnormalities that involve the vertebral body and facets but spare the pedicles are usually benign (,,,,,Figs 8, ,,,,,9).

When a single-head system is used, 64 angular samplings (20 sec/sample) are acquired on a 128 × 128 × 16 matrix. Delayed images demonstrate focal fusiform uptake in the lesion; this uptake often occurs at the junction of the middle and distal thirds of the tibia (,25).

Figure 6. The presence of multiple, randomly distributed areas of increased uptake of varying size, shape, and intensity is highly suggestive of bone metastases (,Fig 4). At scintigraphy, spontaneous osteonecrosis is characterized by focally increased radiotracer accumulation, usually in the medial femoral condyle, although the lateral femoral condyle and tibia may also be involved (,Fig 21) (,38). 1, Seminars in Roentgenology, Vol. 1, Journal of Korean Neurosurgical Society, Vol. 30, No. Anterior (left) and posterior (right) whole-body scintigrams show diffuse, irregularly increased activity throughout the appendicular and axial skeleton.
