Limitations of computed tomography coronary angiography.
t seems so simple and elegant. Fifty years after the ntroduction of coronary angiography, advances in technolgy allow imaging of the coronary arteries noninvasively sing multidetector computed tomography (CT) scanners 1). Within a few short years, these imaging systems have egun appearing everywhere, first in hospitals and clinics, hen in individual doctors’ offices, offering the promise of afe and painless detection of coronary obstructions (2). eekend courses allow the members of our profession to learn” this new technology and apply it routinely to patient are (3). The manufacturers of the equipment, all large ultinational providers of radiological imaging devices, are uite pleased to show practitioners how they can rapidly ecoup their million-dollar investments (4,5). What could ossibly be wrong with this picture? Medical progress to the etterment of patients (and practitioners).
