scintigraphy

 [sin-tig´rah-fe]
production of two-dimensional images of the distribution of radioactivity in tissues after internal administration of a radiopharmaceutical imaging agent, the images being obtained by a scintillation camera. adj., adj scintigraph´ic.
exercise thallium scintigraphy myocardial perfusion using thallium 201 as a tracer and performed in conjunction with an exercise stress test.
gastroesophageal scintigraphy scintigraphy of the esophagus and stomach. A radioisotope is introduced into the stomach and scintillation measurements are taken over both the esophagus and the stomach; usually used to determine the degree of gastroesophageal reflux.
gated blood pool scintigraphy equilibrium radionuclide scintigraphy.
infarct avid scintigraphy that performed following myocardial infarction to confirm infarction as well as detect, localize, and quantify regions of myocardial necrosis. A radiotracer that concentrates in these regions, usually technetium 99mTc pyrophosphate, is administered intravenously and images are obtained with a gamma camera. For maximal sensitivity, the study is performed between 24 and 72 hours after infarction.
myocardial perfusion scintigraphy that performed using a radiotracer that traverses the myocardial capillary system and enters myocardial cells; after the radionuclide, usually thallium 201, is introduced into the bloodstream, regional myocardial blood flow and cell viability are assessed using immediate and delayed images. Scintigraphy is frequently combined with an exercise stress test (see exercise testing) in the diagnosis of coronary artery disease.

scin·tig·ra·phy

(sin-tig'ră-fē),
A diagnostic procedure consisting of the administration of a radionuclide with an affinity for the organ or tissue of interest, followed by recording the distribution of the radioactivity with a stationary or scanning external scintillation camera. See: gamma camera.

scintigraphy

Imaging The creation of 2-D images of the distribution of a radionuclide in tissue after administration. See Brain scintigraphy, Dimercaptosuccinic acid scintigraphy, Dipyridamole-thallium scintigraphy, Immunoscintigraphy, Infarct-avid scintigraphy, Perfusion scintigraphy, Whole gut scintigraphy.
