In vivo assessment of three dimensional coronary anatomy using electron beam computed tomography after intravenous contrast administration.

Intravenous coronary angiography with electron beam computed tomography (EBCT) allows for the non-invasive visualisation of coronary arteries. With dedicated computer hardware and software, three dimensional renderings of the coronary arteries can be constructed, starting from the individual transaxial tomograms. This article describes image acquisition, postprocessing techniques, and the results of clinical studies.

Magnetic resonance imaging of the coronary arteries: clinical results from three dimensional evaluation of a respiratory gated technique.

Background: Magnetic resonance coronary angiography is challenging because of the motion of the vessels during cardiac contraction and respiration. Additional challenges are the small calibre of the arteries and their complex three dimensional course. Respiratory gating, turboflash acquisition, and volume rendering techniques may meet the necessary requirements for appropriate visualisation.

Magnetic resonance imaging of the coronary arteries: anatomy of the coronary arteries and veins in three-dimensional imaging.

Magnetic resonance imaging of coronary arteries will visualize, besides the arteries, the myocardium, blood in the cavities and cardiac veins. This will hamper the application of projectional visualization techniques such as those used in conventional coronary angiography. Volume rendering, a different visualization technique, can be used to create a three-dimensional impression of a magnetic resonance data set on a two-dimensional surface.

Intravenous coronary angiography by electron beam computed tomography: a clinical evaluation.

Background: -Noninvasive detection of coronary stenoses with electron beam CT (EBCT) after intravenous injection of contrast medium has recently emerged. We sought to determine the diagnostic accuracy of EBCT angiography in the clinical setting using conventional coronary angiography as the "gold standard."

Methods And Results: Thirty-seven patients (30 men) were investigated.

Breath-hold coronary MR angiography with volume-targeted imaging.

Purpose: To illustrate a new concept for fast coronary artery screening with breath-hold volume targeted magnetic resonance (MR) imaging.

Materials And Methods: Ten volunteers and 25 patients were imaged at a field strength of 1.5 T with an MR system with phased-array-coil reception and capable of echo-planar imaging.

Coronary arteries.

Conventional coronary angiography (CA) is the standard of excellence for the evaluation of coronary artery disease. However, non-invasive imaging modalities have developed that can play an important clinical role in the diagnosis. Magnetic resonance imaging (MRI) can offer a comprehensive evaluation of the heart and the coronary arteries by virtue of its high soft tissue contrast capabilities, double-oblique tomographic sections and the possibility of quantifying physiological parameters without need of ionizing radiation.
