Computed Tomography Coronary Angiography: is There Any Progress?
Keywords:computed tomography, CT coronary angiography, coronary artery disease, radiation, calcium score
AbstractSignificant improvements in technical capabilities of multislice computed tomography (MSCT) scanners over the recent years have resulted in better temporal and spatial resolution of computed tomography coronary angiography (CTCA) and a decrease of the acquisition time and reduction of the radiation dose. CTCA has been validated as having an excellent negative predictive value for ruling-out coronary artery disease (CAD) in populations with low-to-intermediate pretest probability and a high accuracy for detecting CAD in patients with atypical chest pain. It can, also, aid in decision-making for the clinical management of patients found to have significant coronary artery stenoses and in the follow-up these patients. The recent improvements of this technology are herein briefly overviewed.
