First performance evaluation of a dual-source CT (DSCT) system

Assessment of thoracic aortic elasticity: a preliminary study using electrocardiographically gated dual-source CT

“…An additional tool is to use, DSCT thereby increasing available temporal resolution to 83 ms. This permits more accurate vessel measurements at higher heart rates, and the inclusion of more patients or the reduction in use of heart controlling medication for the patients [19]. In this study, no medication was used to reduce the heart rate and all CT data sets were successfully evaluated.…”

Accuracy of dual-source computed tomography in quantitative assessment of low density coronary stenosis—a motion phantom study

“…Influence of vessel size, motion, and display settings As a limitation of the spatial resolution of MDCT, limited assessment in small vessels is widely accepted and discussed in the literature [14,24]. Using 16-slice MDCT both 3 mm [20] and 3.5 mm [25] have been reported as minimal outer luminal diameters for sufficient stenosis quantification.…”

“…Collimation was 2 · 32×0.6 mm with the z-flying focal spot technique resulting in a spatial resolution of 0.6 mm in plane and 0.5 mm through plane [14]. For static imaging, pitch was set at 0.21 and for the motioned imaging at 0.32, adapted to the simulated heart rate of 70 bpm.…”

Italian multicenter, prospective study to evaluate the negative predictive value of 16- and 64-slice MDCT imaging in patients scheduled for coronary angiography (NIMISCAD-Non Invasive Multicenter Italian Study for Coronary Artery Disease)

“…The extension of MDCT system usage with higher temporal resolution (<100 ms) may extend the application of this technology for the assessment of CAD in a high probability pre-test population with extensive calcifications and without heart rate control [33][34][35][36]. The employment of hybrid PET/MDCT [37] or SPECT/MDCT equipment with image fusion [38] may offer the opportunity for a comprehensive non-invasive evaluation of the presence of CAD and its consequences, both in the coronary arteries and myocardium.…”
