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. EBCT coronary angiography is a promising coronary artery imaging technique. Currently it is a reasonably robust technique for the visualisation and assessment of the left main
and left anterior descending coronary artery. The right and circumflex
coronary arteries can be visualised less consistently. Improvements in
image acquisition and postprocessing techniques are expected to improve
visualisation and diagnostic accuracy of the technique.
