“…Dill et al [18] recently pointed out that the radiation dosage relation of CTA and CA is more favorable for patients with CABG than for patients without. Although the mean effective dose in MSCT is higher than in CA, the difference between both methods is minor compared to patients without bypass grafts [18].…”

“…Tube current was 360 mA, and tube voltage was 120 kV for both tubes. In accordance with previously published studies for dose reduction algorithms, [15][16][17] ECG-gated tube current modulation and automatic radiation exposure control were both used in all patients, and the pulsing window was fixed from 65% to 70% of the RRcycle with heart rates <70 bpm, or from 40% to 70% of the RR-cycle with heart rates >70 bpm.…”

Background Computed tomography (CT) enables detection of coronary artery stenoses, but its use is limited by deficient evaluation at elevated heart rates. The accuracy of dual-source CT (DSCT) for the detection of coronary artery disease (CAD) was assessed in 76 patients at high probability of CAD without heart rate control and compared with quantitative coronary angiography (QCA). Methods and ResultsThe 76 patients (47 males, mean age 65.5±10 years) underwent DSCT without preceding heart rate control. Data sets were evaluated by 2 observers in consensus with respect to stenoses >50% decreased diameter. QCA served as the standard of reference. Mean heart rate during scanning was 68±9 beats per min, and the average Agatston score was 337±560. Of 1,160 coronary artery segments, all but 3 were visualized artefactfree; 58 coronary stenoses were correctly detected by CT angiography. In the segment-based analysis, sensitivity was 98.3%, specificity 99.2% and accuracy 99%; patient based analysis revealed a sensitivity of 100%, specificity of 83.3% and overall accuracy of 92.1%. Conclusions Even at elevated heart rates, DSCT can reliably detect coronary artery stenoses and the results correlate well with those for invasive coronary angiography. (Circ J 2009; 73: 316 -322)

“…Finally, CTA involves radiation exposure. The effective radiation dose of CTA has progressively declined to the 1-to 5-mSv range, depending on whether the study is prospectively or retrospectively gated (60); diagnostic ICA delivers a mean effective radiation dose of approximately 2-2.5 mSv (61). Dose reduction techniques continue to be improved, further reducing radiation exposure, but the risks of higher radiation doses must be considered in decisions about the appropriate testing modality for a particular patient.…”

Cardiac CT angiography has become an important tool for the diagnosis and treatment of congestive heart failure. Differentiation of ischemic from nonischemic cardiomyopathy; evaluation of myocardial perfusion; characterization of hypertrophic cardiomyopathy, left ventricular noncompaction, and arrhythmogenic right ventricular dysplasia; and delineation of congenital heart defects and valvular abnormalities are the primary diagnostic applications. Therapeutic use includes visualization of the coronary venous anatomy for optimal implementation of cardiac resynchronization therapy and evaluation of left ventricular assist devices and transplant vasculopathy.
