“…This interference, however, is more pronounced in 3D reconstructions than in longitudinal and cross-sectional reformatted images, which are the projections most frequently used for arterial measurement. 8,19,21,22 Images of good diagnostic quality were obtained in all cases, confirming the effectiveness of the protocol used. Quantitative analysis based on both the visual aspect and estimate of blood flow within the stented vessel was effective in that it showed absence of hemodynamically significant in-stent obstructions.…”

objective: To assess the performance of multidetector computed tomography in determining late clinical outcomes of patients undergoing sirolimus-eluting stent implantation.Methods: Thirty patients, successfully submitted to sirolimus-eluting stent implantation for more than six months, were selected to participate in the study. All underwent invasive angiography and intravascular ultrasound following CT angiography using iodinated contrast medium at a dose of 1.5 ml/kg. Results:Mean proximal reference diameter was 3.01 ± 0.31 mm by tomography and 3.14 ± 0.31 mm by angiography (p = 0.04). When the left circumflex artery was excluded from the analysis, the difference between both examinations was no longer significant (tomography = 3.01 ± 0.32 mm; angiography = 3.10 ± 0.30 mm, p = 0.65). Mean distal reference diameter was 2.86 ± 0.30 mm by tomography and 2.92 ± 0.32 by angiography (p = 0.25). Mean in-stent minimal lumen diameter was 2.85 ± 0.25 mm by tomography and 2.85 ± 0.29 mm by angiography (p = 0.27). Mean minimal in-stent crosssectional area was 7.19 ± 1.47 mm 2 by tomography and 6.90 ± 1.52 mm 2 by intravascular ultrasound (p = 0.36), but there was only a weak correlation between these measurements (r = 0.33). Conclusion:Computed tomography allows the qualitative assessment of sirolimus-eluting stents, accurate estimate of proximal and distal reference diameters of the target vessel, and in-stent minimal lumen diameter. Its correlation with measurements performed using intravascular ultrasound, however, is less strong. key words: Coronary failure, computed tomography, quantitative angiography, intravascular ultrasound.

“…3 With four-slice CT, a sensitivity of 58-86% for the detection of coronary stenosis has been reported, [10][11][12][13][14] but up to 32% of the vessels had to be excluded from analysis because of a decreased image quality. 10 Using 16-slice CT, overall sensitivity including all segments was reported to be between 73 and 95%, depending on the diameter of the segment, the modality of analysis, and the patient selection criteria.…”

Aims The aim of our study was to investigate the accuracy of 64-slice computed tomography (CT) for assessing haemodynamically significant stenoses of coronary arteries. Methods and results CT angiography was performed in 67 patients (50 male, 17 female; mean age 60.1 + 10.5 years) with suspected coronary artery disease and compared with invasive coronary angiography. All vessels !1.5 mm were considered for the assessment of significant coronary artery stenosis (diameter reduction .50%). Forty-seven patients were identified as having significant coronary stenoses on invasive angiography with 18% (176/1005) affected segments. None of the coronary segments needed to be excluded from analysis. CT correctly identified all 20 patients having no significant stenosis on invasive angiography. Overall sensitivity for classifying stenoses was 94%, specificity was 97%, positive predictive value was 87%, and negative predictive value was 99%. Conclusion Sixty-four-slice CT provides a high diagnostic accuracy in assessing coronary artery stenoses.

“…19 However, in some patients, heart rates Յ60 bpm could not always be achieved at the expense of poor coronary artery visibility. 20 Two of the studies 21,22 excluded Ϸ30% of coronary segments mainly because of image degradation from cardiac motion. The image artifacts and the number of excluded coronary segments may be significantly reduced (to Ϸ10%) by the use of ␤-blocker and careful patient selection.…”
