“…In contrast to MDCT systems with lower temporal resolution, dual-source technology has demonstrated sufficient clinical robustness, even in the presence of arrhythmias (23) and without the use of negative chronotropic pretreatment in patients with higher heart rates (12-18, 29, 30). In this study, we evaluated arteries, excluding non-diagnostic segments from analysis.…”

“…The results of the CCTA detection of significant stenoses (lesions >50%) were compared with the results of conventional coronary angiography according on a: (a) per-segment basis, comparing each segment in every vessel; (b) per-vessel basis, looking for the presence of significant lesions of the major coronary vessels; and (c) per-patient basis, looking for the presence of any significant stenotic vessel lesions in each patient (2,(12)(13)(14)(15)(16)(17)23).…”

Purpose: To assess the diagnostic accuracy of dual-source computed tomography (DSCT) in the detection of coronary artery stenosis (CAS) based on patient heart rate and calcium scores. Materials and Methods: This study included 102 patients (46 male, 56 female; mean age 64.1 ± 10.6 years; age range 37-92 years) with chest pain and who underwent DSCT as well as invasive coronary angiography. Patients were classified into three groups according to mean heart rate (<70 bpm, 70-90 bpm, and >90 bpm) and also classified in three groups according to Agatston calcium scores (<100, 100-400, and >400). Results: For patients with a mean heart rate < 70 bpm, the sensitivity, specificity, PPV, NPV, and diagnostic accuracy of DSCT on a per-vessel basis were 98.5%, 98.2%, 93.6%, 99.1%, and 97.9%, respectively, 99.2%, 99.2%, 97.4%, 99.5%, and 99%, respectively, for 70-90 bpm; and 91.7%, 97.9%, 88.5%, 96.7%, and 95.7%, respectively, for >90 bpm. For calcium scores <100, the sensitivity, specificity, PPV, NPV, and diagnostic accuracy of DSCT on a per-vessel basis were 97.2%, 99.0%, 97.0%, 99.3%, and 98.6%, respectively, 98.5%, 99.5%, 96.2%, 99.4%, and 99.0%, respectively, for calcium scores 100-400, and 95.8%, 97.0%, 87.4%, 97.2%, and 95.6%, respectively, for calcium scores >400. Conclusion: DSCT showed a high diagnostic accuracy and negative predictive value, regardless of heart rate and calcium score.

“…One small study has reported on an initial experience of coronary CTA in 15 patients (mean age 58 years) with atrial fibrillation and suspected coronary disease referred for invasive angiography. 98 Imaging was done with a 64-channel dual-source CT, which provides a nominal temporal resolution of about one fourth of a gantry rotation or about 83 milliseconds. The mean heart rate during imaging of the study cohort was 84Ϯ9 beats per minute.…”
