myocardial perfusion imaging

imaging /imag·ing/ (im´ah-jing) the production of diagnostic images, e.g., radiography, ultrasonography, or scintillation photography.

color flow Doppler imaging  a method of visualizing direction and velocity of movement using Doppler ultrasonography and coding them as colors and shades, respectively.

echo planar imaging  a technique for obtaining a magnetic resonance image in less than 50 msec.

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.

gated magnetic resonance imaging  a method for magnetic resonance imaging in which signal acquisition is gated to minimize motion or other artifacts.

hot spot imaging , infarct avid imaging see under scintigraphy.

magnetic resonance imaging  (MRI) a method of visualizing soft tissues of the body by applying an external magnetic field that makes it possible to distinguish between hydrogen atoms in different environments.

myocardial perfusion imaging  see under scintigraphy.

pyrophosphate imaging  infarct avid scintigraphy.

technetium Tc 99m pyrophosphate imaging 

1. infarct avid scintigraphy.

2. any type of imaging using Tc 99m pyrophosphate as an imaging agent.

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.

magnetic resonance imaging see magnetic resonance imaging.

myocardial perfusion imaging myocardial perfusion 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
