“…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.…”

“…However, using only two phases resulted in only moderate correlation with the short-axis approach for EF, and it also showed a significant overestimation of myocardial mass and significantly larger limits of agreement for EF and ESV with respect to the region-growing approach using 10 phases, thus proving to be inferior to the manually adjusted region-growing approach. Furthermore, using all 10 phases of the cardiac cycle may also lead to further diagnostic information, such as regional assessment of LV function [13] or the evaluation of the aortic valve [25,26], especially as part of the emerging ''triple-rule-out'' protocols [27][28][29]. Any increase in the number of phases of the cardiac cycle used for analysis, on the other hand, may only lead to a minimal increase of diagnostic gain, as recently reported by Puesken et al [30], but requiring larger storage and network capacities.…”

“…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.

“…Numerous studies show excellent correlation and concordance between LV volumes and EF obtained by CCT and other modalities such as TTE and MRI. [22,23] For example, Greupner et al performed a head-to-head comparison of LV function assessment between 64-row cardiac CT and 3 other imaging modalities (2D and 3D echocardiography, and cineventriculography), using MRI as a reference standard. [24] They found CCT to be superior to the other 3 modalities in assessing global LV functional parameters, showing significantly higher correlation between CT and MRI in terms of LVEF (r = 0.89) and LV volumes: end-diastolic volume (r = 0.90), end-systolic volume (r = 0.96), with the exception of stroke volume which was significantly overestimated.…”

Sudden cardiac death (SCD) is the leading cause of death in the U.S., and many of these events are attributable to malignant ventricular arrhythmias such as sustained ventricular tachycardia (VT). Most of the efforts to identify arrhythmia precipitants in these patients are based on imaging to look for myocardial or coronary artery disease. As advances in cardiac computed tomography (CCT) are made, it has demonstrated its usefulness in identifying structural intracardiac pathology and measuring parameters of cardiac anatomy and function. In this article we review the different etiologies of VT/SCD that are identifiable by CCT, and its potential usefulness in the workup for VT/SCD.

“…However, cardiac CT has the capability of providing reliable and reproducible quantification of left and right ventricular systolic functions and chamber volumes, when compared with other non-invasive cardiac imaging modalities. [8][9][10][11][12][13][14][15] Evaluation of left and right ventricular function has been shown to have important prognostic value in patients with coronary artery disease, acute coronary syndromes and pulmonary emboli. [16][17][18] It is conceivable that if information on myocardial function could be provided using cardiac CT without significant additional radiation expense, independently or at the time of coronary CTA, this might provide a useful and robust alternative means of determining accurate quantitative volumetric and functional data.…”
