[Non-invasive assessment of coronary artery bypass grafts by computed tomography: comparison with conventional coronary angiography].
INTRODUCTION AND OBJECTIVES Although it has been demonstrated that the diagnostic accuracy of computed tomography in the non-invasive assessment of major epicardial coronary arteries is high, only a few studies have evaluated the technique's reliability in assessing coronary artery bypass grafts. The aim of this study was to determine the diagnostic accuracy of multidetector computed tomography...
متن کاملComputed Tomography Angiography of Coronary Artery Bypass Grafts: Low Contrast Media Volume Protocols Adapted to Tube Voltage.
OBJECTIVE The aim of this study was to evaluate the potential of contrast media (CM) reduction in computed tomography angiography (CTA) of coronary artery bypass grafts (CABGs) when adapting CM volume to automatically selected tube voltages. MATERIAL AND METHODS Sixty consecutive patients (mean age, 71 ± 14.5 years) with a total of 176 CABGs (692 bypass segments) underwent contrast-enhanced p...
متن کاملComputed tomographic assessment of coronary artery bypass grafts.
Twenty four patients with 65 coronary artery bypass grafts were studied by computed tomography and angiogrphy within a 10 day period in order to assess graft patency and graft flow. In the assessment of graft patency computed tomography had an accuracy of 93% and in that of graft flow one of 91%. These results indicate that computed tomography is an accurate method for assessing graft patency a...
متن کاملComputed tomography coronary angiography.
Recent developments in computed tomography technology have made imaging of the coronary arteries possible. All the same, the rapid motion and small dimensions of the coronary vessels make coronary computed tomography angiography (coronary CTA) challenging. With the last generations of 16- and 64-slice computed tomography and adequate patient preparation (which includes lowering of the heart rat...
متن کاملCoronary Computed Tomography Angiography
Coronary computed tomographic angiography (cCTA) as a noninvasive approach underlies a rapid technological development with an impressive improvement of spatial and temporal resolution of the images. Therefore, it has become an accurate and costeffective method to detect or exclude obstructive coronary artery disease (CAD) in patients with low to medium cardiovascular risk profile, as recommend...
