“…The sensitivity of MSCT in detecting proximal segment obstructions was 95%, its specificity was 92%, positive predictive value was 92% and negative predictive value was 95% (Table 1, 2). [24][25][26][27][28][29][30][31] In the group where the obstructions of the middle coronary segments were evaluated, a total of 283 segments were evaluated. In 98% of these lesions, MSCT coronary angiography results were in correlation with CCA in regards to the detectability of the lesion (true positive results) (Table 3).…”

“…The selection of a normal reference area by proportioning with the narrowest measured diameter also results in mistakes. In a study performed by making a comparison with a 64 slice CT and intravascular ultrasonography, a high correlation was reported between areal obstruction measurements (25). In order to obtain more precise and reliable results in the evaluation of coronary segments, we believe that studies comparing CCA and MSCT coronary angiography should be performed on larger patient groups by standardizing these parameters.…”

“…[1][2][3][4][5][6] With single-source 64-slice CTA, most investigators recommend lowering the patient's heart rate to G65 beats per minute (bpm) to achieve stable image quality. [7][8][9][10] In this range, diagnostic image quality can be obtained for all coronary arteries at a single reconstruction interval at mid-diastole.…”

Is It Possible to Predict Heart Rate and Range during Enhanced Cardiac CT Scan from Previous Non-enhanced Cardiac CT?

The effect of heart rate and variation during cardiac computed tomography (CT) on the examination quality. The purpose of this study is to investigate whether it is possible to predict heart rate and range during enhanced cardiac computed CT scan from previous non-enhanced cardiac CT scan. Electrocardiograph (ECG) files from 112 patients on three types of cardiac 64-slice CT (nonenhanced, prospective ECG-triggered and retrospective ECG-gated enhanced scans) were recorded. The mean heart rate, range (defined as difference between maximal and minimal heart rates) and the range ratio (defined as maximal heart rate divided by minimal heart rate) during the scans were compared. Scan time was 4.8, 4.6, and 7.3 s on non-enhanced, prospective ECG-triggered and retrospective ECG-gated scans, respectively (pG0.0001). The heart rates were not significantly different (60±9 beats per minute (bpm), 60±9 and 61±10 bpm; p=0.64). Heart rate on the enhanced scan markedly correlated with that of the non-enhanced scan (r=0.78 and 0.74). In contrast, the ranges of heart rate were 2±5, 4±8, and 8± 21 bpm, with different range ratios (1.04, 1.07, and 1.14; pG0.0001). Correlation of heart rate ranges between nonenhanced scan versus prospective ECG-triggered scan was low (r=0.27) and that between non-enhanced scan versus retrospective ECG-gated scan negligible (r= −0.027).Heart rate on enhanced cardiac CT, in most cases, can be predicted from a non-enhanced scan. Heart rate range on enhanced cardiac CT, however, is hard to predict from the non-enhanced scan.

Reduction of coronary artery multi-slice computed tomographic radiation and maintained image interpretability by parameter optimization: the multicenter RAMBO study

Multi-slice computed tomography (MSCT) has proven in several studies to have a high diagnostic accuracy for the detection or exclusion of coronary artery disease. A major concern with coronary MSCT, however, is the associated radiation exposure of patients. Recent studies suggest that use of a 64-slice scanner is associated with a non-negligible lifetime attributable risk of cancer. Several strategies can be used to reduce patient exposure in coronary MSCT. The purpose of this multicenter study was to investigate the effects of the adjustment of tube voltage and current on radiation dose and image interpretability. MSCT with retrospective ECG gating was performed in 315 patients. The dose-length product (DLP) in the patients enrolled with the dose reduction protocol resulted in a 36% overall reduction in the mean radiation dose (911 ± 289 mGy.cm) compared with the standard protocol (1427 ± 226 mGy.cm, p < 0.001). Nevertheless, image interpretability was maintained. This study on coronary MSCT demonstrates that the radiation dose can be significantly reduced by parameter optimization, with maintained image interpretability.
