“…This is consistent with the results of previous domestic and foreign studies (Uusitupa et al, 1990;Henneman et al, 2006;Salm et al, 2006;Butler et al, 2007;Annuar et al, 2008;Stolzmann et al, 2008). Compared with electrocardiographic measurements, the ESV, EDV, and SV values for patients measured by DSCT were slightly lower, while those for EF were slightly higher.…”

“…The introduction of DSCT represented a leap forward for CT, shortening its time resolution to 83 ms, and allowing clear images of systolic and diastolic phases to be obtained from patients with a fast heart rate without needing to give β2-receptor blockers, which have adverse effects on cardiac function. In addition, data obtained from coronary angiography can be used to assess calcification scores, coronary artery stenosis, and valvular morphology, as well are to detect myocardial ischemia and infarction, and so on, without needing additional contrast agents or radiation (Ropers et al, 2007;Annuar et al, 2008;Brodoefel et al, 2008).…”

ABSTRACT. We aimed to assess parameters reflecting left ventricular function by dual-source computed tomography (DSCT) with echocardiography (ECG) as control. Fifty-eight patients with coronary heart disease (CHD) were recruited from January to June 2011; 29 CHD patients had type II diabetes. All patients were assessed by cardiac DSCT and ECG examination. DSCT and ECG correlated well for ejection fraction (EF) (r = 0.70), end-systolic volume (ESV) (r = 0.87), stroke volume (SV) (r = 0.83), and end-diastolic volume (EDV) (r = 0.90). The mean ESV and EDV values measured by the two methods in CHD patients with type II diabetes were higher than those in non-diabetic patients, whereas the mean EF was lower. DSCT is an accurate and practical method for assessing left ventricular function.

“…MDCT has shown promising results for the evaluation of global LV function [7][8][9][10][11][12][13], but so far, being based on short-axis reformations as adapted from MRI evaluation, it has been quite time-consuming [15,16]. An ideal method would be time-efficient and take advantage of the high spatial resolution of MDCT, while showing little and (e) myocardial mass (MM) for the manually adjusted region-growing (RG_man) approach using all 10 phases of the cardiac cycle and the manually adjusted region-growing approach using motion mapping (RG_MM), in comparison with the semi-automatic short-axis approach (SA) in 35 patients.…”

“…As MDCT allows the acquisition of a complete and continuous volumetric data set, as well as the related electrocardiogram, it is possible to accurately analyse left ventricular (LV) function [4,[7][8][9][10][11][12][13]. For this, reconstructing short-axis slices, identifying cardiac borders and using Simpson's rule to calculate the resulting volume is the method of choice.…”

Objective: Global cardiac function assessment using multidetector CT (MDCT) is timeconsuming. Therefore we sought to compare an automatic software tool with an established semi-automatic method. Methods: A total of 36 patients underwent CT with 6460.5 mm detector collimation, and global left ventricular function was subsequently assessed by two independent blinded readers using both an automatic region-growing-based software tool (with and without manual adjustment) and an established semi-automatic software tool. We also analysed automatic motion mapping to identify end-systole. Results: The time needed for assessment using the semi-automatic approach (12:12¡6:19 min) was reduced by 75-85% with the automatic software tool (unadjusted, 01:34¡0:29 min, adjusted, 02:53¡1:19 min; both p,0.001). There was good correlation (r50.89; p,0.001) for the ejection fraction (EF) between the adjusted automatic (58.6¡14.9%) and the semi-automatic (58.0¡15.3%) approaches. Also the manually adjusted automatic approach led to significantly smaller limits of agreement than the unadjusted automatic approach for end-diastolic volume (¡36.4 ml vs ¡58.5 ml, p.0.05). Using motion mapping to automatically identify end-systole reduced analysis time by 95% compared with the semi-automatic approach, but showed inferior precision for EF and end-systolic volume. Conclusion: Automatic function assessment using MDCT with manual adjustment shows good agreement with an established semi-automatic approach, while reducing the analysis by 75% to less than 3 min. This suggests that automatic CT function assessment with manual correction may be used for fast, comfortable and reliable evaluation of global left ventricular function.

“…With the continuous improvement of time and spatial resolution in MSCT, multi-slice spiral CT coronary artery angiography (MSCTCA) could be used for the evaluation of coronary arterial stenosis, and the original data could also be used for a one-stop cardiac function determination. Studies have shown that 64-layer SCTCA has high sensitivity and specificity in the diagnosis of coronary artery stenosis, and its results for cardiac function parameters were found to be highly correlated with the gold standard cMRI (Annuar et al, 2008;Groen et al, 2009;Zhang et al, 2009;Ito et al, 2010). In the present study, 128-layer SCTCA was used, along with retrospective ECG gating techniques (Mollet et al, 2005;Lu et al, 2008), to continuously scan several cardiac cycles, and the real-time dynamic 4-D raw image data of the systolic and diastolic ends, namely the "time-space" periods, were analyzed for the one-stop noninvasive evaluation of coronary artery stenosis, left ventricular structure and systolic function (Ko et al, 2010;Takx et al, 2012).…”

ABSTRACT. The aim of this study was to determine the impact of multi-slice computed tomography (MSCT) evaluation of coronary artery stenosis on left heart structure and systolic function. Coronary artery CT angiography was performed in 200 patients diagnosed with coronary heart disease, and then according to the AHA coronary artery 17-segment fractionation method, the Gensini score (GS) was determined for every narrow segment, and one-stop assessment of the correlation between left heart structure and function was performed. After the grouping of GS quartiles from low to high, there were differences between different patients with regard to LVDD, LADD, LVEDV, LVESV, MM, LVEF, and FS, while no difference in SV and CO. GS showed linear negative correlation with LVEF and FS, and linear positive correlation with LVDD, LADD, LVEDV, LVESV, and MM, while no correlation with SV and CO. That is, GS of coronary artery stenosis was negatively correlated with left ventricular systolic function and positively correlated with myocardial mass. The narrower the coronary artery, the worse the cardiac function and the higher the myocardial hypertrophy.
