scintigraphy

scintigraphy /scin·tig·ra·phy/ (sin-tig´rah-fe) the production of two-dimensional images of the distribution of radioactivity in tissues after the internal administration of a radiopharmaceutical imaging agent, the images being obtained by a scintillation camera.scintigraph´ic

exercise thallium scintigraphy  myocardial perfusion using thallium 201 as a tracer and performed in conjunction with an exercise stress test.

gated blood pool scintigraphy  equilibrium radionuclide angiocardiography.

infarct avid scintigraphy  that performed following myocardial infarction to confirm infarction as well as detect, localize, and quantify areas of myocardial necrosis by means of a radiotracer that concentrates in necrotic regions.

myocardial perfusion scintigraphy  that performed using a radiotracer that traverses the myocardial capillary system; immediate and delayed images are obtained to assess regional blood flow and cell viability.
