“…39,40 By providing a temporal resolution of 83 ms in a monosegment reconstruction mode, DSCT enables motion artefact-free visualization of coronary arteries, independent of heart rate, and therefore a significant decrease of motion artefacts in clinical practice. 6,7 In this prospective study we assessed the feasibility of new DSCT technology to detect coronary artery stenoses in a cohort of 76 consecutive patients without precedent heart rate lowering medication. An overall diagnostic accuracy of 99.1% and excellent NPV of 99.9% in segment-based analysis was achieved without excluding any coronary segments from statistical analysis because of artefacts.…”

“…6 Recent studies using DSCT have shown encouraging results for visualization of the coronary arteries independent of heart rate; however, only small numbers of patients have been included and the correlation to quantitative coronary angiography (QCA) has so far barely been provided. [7][8][9][10] Thus, the purpose of the present study was to assess the feasibility of DSCT for detection of relevant coronary artery stenoses in a cohort of 76 patients with clinically suspected coronary artery disease (CAD) and compare the results with those from invasive angiography without preceding heart rate control.…”

“…Recently, Nazeri et al confirmed high diagnostic accuracy of 64-slice CTA for noninvasive assessment of bypass grafts in symptomatic patients after CABG [13]. The introduction of dual-source CTA scanner with 2 x-ray tubes and detectors offers an alternative approach to improve temporal resolution for cardiac imaging [13][14][15]. In the present study, the dualsource CTA demonstrated a sensitivity of 100% and specificity of 92% for the detection of significant graft disease, and compares favorably with the reported diagnostic accuracy of 64-slice CTA.…”

“…Results of studies using 64-slice CTA were promising for the detection of significant stenoses and occlusions in bypass grafts and distal runoffs [9][10][11][12][13]. Recently, a novel dual-source CTA scanner has been introduced that offers the potential for improved temporal resolution [14][15][16]. However, till now the ability of dualsource CTA to detect bypass graft disease has not been well established.…”

“…65,66 Furthermore, extensive coronary artery calcification (coronary calcium score >400) still limits the diagnostic accuracy of CCTA, in particular lowering the sensitivity to some extent due to false positive results, and this is being addressed with improvements in CT imaging. 67,68 Thirdly, CCTA has superior spatial resolution which allows it to demonstrate excellent visualization of coronary lumen change, however, it has limited value in the diagnostic evaluation of myocardial ischemia. The presence of anatomic lesions does not necessarily correlate with functional significance of CAD, which refers to decreased myocardial perfusion.…”
