imaging

 [im´ij-ing]

the production of diagnostic images, e.g., radiography, ultrasonography, or scintigraphy.

digital subtraction imaging a technique in radiography in which electronic subtraction allows the visualization of individual images; see also digital subtraction angiography.

electrostatic imaging a method of visualizing deep structures of the body, in which an electron beam is passed through the patient and the emerging beam strikes an electrostatically charged plate, dissipating the charge according to the strength of the beam. A film is then made from the plate.

gated cardiac blood pool imaging equilibrium radionuclide angiocardiography.

horizontal beam imaging a grid positioning technique in radiology in which the grid cassette is positioned with its lead lines perpendicular to the floor.

hot spot imaging (infarct avid imaging) infarct avid scintigraphy.

myocardial perfusion imaging

A technique in which the regional distribution of blood throughout the myocardium, is determined by injecting a radiopharmaceutical–eg, 201Tl. or 99mTc and capturing images with a gamma–scintillation camera; by determining blood and oxygen distribution, MPI informs on the hemodynamics and functional effect of coronary arterial stenosis
