imaging (redirected from digital subtraction 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.

1. Visualization of internal body organs, tissues, or cavities using specialized instruments and techniques for diagnostic purposes.

2. The use of mental images to influence bodily processes, especially to control pain.

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.

nuclear imaging

see scintigraphy.

organ imaging

outlining the size and location of organs by the injection of nuclides into the animal and observing their location by the use of a rectilinear scanner or a scintillation camera. See also scintigraphy.

imaging

The term is used in 2 different areas of diagnostic medicine Radiology The production of non-invasive images of body regions using ionizing radiation–eg, CT or mammography, or electromagnetic radiation–eg, MRI or ultrasonography, with/without radiocontrast; the information obtained is then analyzed by a computer to produce a 2-D display Types of information provided Anatomic–CT, MRI, mammography, ultrasonography, metabolic–PET, SPECT-single photon emission CT or data on electrical activity–SQUID.
