“…With average rotational geometry, six planes provided accurate estimation of LV volumes and EF. 8,9 Actually, in the present study, accurate determination of LV volumes and EF could be obtained by 3DE using as few as six apical images, including in patients with regions of asynergy. …”

“…Another advantage of this system was its average rotational geometry, which used a small number of apical rotated views. [7][8][9] The average rotational geometry was designed to be fast and simple to be used in clinical situation. An important characteristic of this geometry was that the slice resolution was unchanged along the imaging axis at the same radial distances and was particularly useful for the whole LV.…”

“…In addition, the average rotational geometry has been applied to LV volume quantification in 3DE. [7][8][9] Rapid acquisition by free-hand scanning and application of average rotational geometry may be useful in quantification of LV systolic function in patients with CAD. Therefore, we designed this study to evaluate the feasibility and accuracy of LV volumes and EF determined by commercially available free-hand 3DE with magnetic tracking system in patients with CAD, by comparison with those by quantitative gated single-photon emission computed tomography (QGS).…”

“…This functional information is usually derived from other diagnostic procedures than CT, i.e. echocardiography or projection X-ray ventriculography, despite their limited accuracy and precision compared with MRI [5]. Due to the improved temporal resolution of 83 ms, DSCT can be regarded as a promising method to acquire functional left ventricular parameters as a complementary information that can be a determined from coronary CT angiography datasets non-invasively and without the need for additional contrast agent or radiation exposure [2].…”

Cardiac magnetic resonance imaging and echocardiography are currently regarded as standard modalities for the quantification of left ventricular volumes and ejection fraction. With the recent introduction of dual-source computedtomography (DSCT), the increased temporal resolution of 83 ms should also improve the assessment of cardiac function in CT. The aim of this study was to evaluate the accuracy of DSCT in the assessment of left ventricular functional parameters with cardiac magnetic resonance imaging (MRI) as standard of reference. Fifteen patients (two female, 13 male; mean age 50.8 +/- 19.2 years) underwent CT and MRI examinations on a DSCT (Somatom Definition; Siemens Medical Solutions, Forchheim, Germany) and a 3.0-Tesla MR scanner (Magnetom Trio; Siemens Medical Solutions), respectively. Multiphase axial CT images were analysed with a semiautomatic region growing algorithms (Syngo Circulation; Siemens Medical Solutions) by two independent blinded observers. In MRI, dynamic cine loops of short axis slices were evaluated with semiautomatic contour detection software (ARGUS; Siemens Medical Solutions) independently by two readers. End-systolic volume (ESV), end-diastolic volume (EDV), ejection fraction (EF) and stroke volume (SV) were determined for both modalities, and correlation coefficient, systematic error, limits of agreement and inter-observer variability were assessed. In DSCT, EDV and ESV were 135.8 +/- 41.9 ml and 54.9 +/- 29.6 ml, respectively, compared with 132.1 +/- 40.8 ml EDV and 57.6 +/- 27.3 ml ESV in MRI. Thus, EDV was overestimated by 3.7 ml (limits of agreement -46.1/+53.6), while ESV was underestimated by 2.6 ml (-36.6/+31.4). Mean EF was 61.6 +/- 12.4% in DSCT and 57.9 +/- 9.0% in MRI, resulting in an overestimation of EF by 3.8% with limits of agreement at -14.7 and +22.2%. Rank correlation rho values were 0.81 for EDV (P = 0.0024), 0.79 for ESV (P = 0.0031) and 0.64 for EF (P = 0.0168). The kappa value of inter-observer variability were amounted to 0.85 for EDV, ESV and EF. DSCT offers the possibility to quantify left ventricular function from coronary CT angiography datasets with sufficient diagnostic accuracy, adding to the value of the modality in a comprehensive cardiac assessment. The observed differences in the measured values may be due to different post-processing methods and physiological reactions to contrast material injection without beta-blocker medication.

“…Twodimensional echocardiography (2DE) derived LAV has been shown to provide a more accurate assessment of LA size than M-mode but the problem of geometric assumption still remains [6,7]. Three-dimensional echocardiography (3DE) has demonstrated superior accuracy for measuring left ventricular volume International Journal of Cardiology 123 (2008) 155 -161 www.elsevier.com/locate/ijcard compared to conventional 2DE and the 3DE reconstruction has been validated for LAV quantification [8][9][10]. Real-time 3DE (RT3DE) allows fast acquisition from a single acoustic window of dynamic pyramidal data structure that encompasses the entire heart [11].…”
