“…The Bland-Altman analysis revealed a good agreement between all CMR measurements computed for the manual and automatic planning methods. The limits of agreement for the automated CMR planning are comparable with previously published ones for interstudy variability (6,15,36,37). Additionally, the percentages of variability were low for all CMR measurements and amounted to 1.9 -4.5%.…”

“…Errors in CMR measurements are due to positional, physiological, planning, and measuring factors that comprise the interstudy variability (1,3,5,12,15,36,37). All of the subjects remained inside the magnet bore during the examination, so positional variability (12) was minimized.…”

“…Planning variability is due to the positional variation and angular deviation of the imaging planes from the optimum, and is prominent only in automated CMR planning. Intraobserver variability (11)(12)(13)16,36,37) arises due to subjectivity in myocardial border tracing by the human observer. The decomposition of the total variation showed that the relative contribution of the interstudy variability factors was significantly larger than that of the intraobserver factor for all CMR measurements (Fig.…”

Purpose: To theoretically and experimentally investigate the influence of the automated cardiovascular magnetic resonance (CMR) scan planning pitfalls, namely inaccurate positioning and tilting of short-axis (SA) imaging planes, on quantification of the left ventricular (LV) dimensions and function. Materials and Methods:Eleven healthy subjects and eight patients underwent CMR. Manually and automatically planned SA sets were acquired. To obtain the quantitative measurements of LV function, one observer performed image analysis twice. The agreement between planning methods, as well as the decomposition of the total variation into interstudy and intraobserver components was measured. Results:The decomposition of the total variation showed that the interstudy factor accounts for 70 -85% of the total variation, while the rest is due to the intraobserver factor. Moreover, the relative contribution of the interstudy factor remains independent from errors in slice positioning and small angular deviation of SA stacks from the optimal orientation. Good agreement between the theoretical and measured variability factors was observed. Conclusion:Global LV function derived from the automatically planned CMR acquisitions yield accurate quantification of the human cardiovascular system. Inaccurate positioning and tilting of SA images does not affect the quantitative measurements of LV function. The computeraided system for automated CMR has proven clinical applicability.

“…Images were obtained using a 3.5 MHz transducer, and images were acquired in standard apical and parasternal two-and four-chamber views. Two readers measured the chamber and wall dimensions using standard recommendations for chamber quantification in consensus [34]. LVEF was calculated using the modified Simpson's method [35,36].…”

ABSTRACT. The aim of this study was to compare the measurement of left ventricular ejection fraction (LVEF) and regional wall motion using 64-slice multidetector CT (MDCT) with that using two-dimensional transthoracic echocardiography (2D-TTE) in a heterogeneous patient population. In 126 patients with angina pectoris, acute myocardial infarction, chronic myocardial infarction, atypical chest pain without coronary artery disease or valvular heart disease, 64-slice MDCT was performed using retrospective electrocardiography gating without dose modulation. 20 phases of the cardiac cycle were analysed to identify the end-diastolic and end-systolic phases and to assess regional LV wall motion. For these measurements, 2D-TTE served as the reference standard. MDCT and 2D-TTE were performed within 10 days of each other. An excellent correlation between MDCT and 2D-TTE was shown for the evaluation of LVEF (59.2¡11% vs 57.9¡10%, respectively; r50.87). LVEF was slightly overestimated by MDCT, when compared with 2D-TTE, by an average of 1.4¡5.6%. Good agreement was obtained between the use of the two techniques, with 94% of the segments scored identically on both modalities (k50.70). MDCT had a sensitivity of 97% and a specificity of 82% when compared with 2D-TTE as the reference standard. In conclusion, the use of 64-slice MDCT can provide comparable results to those using 2D-TTE for LVEF and regional wall motion assessment in a heterogeneous population.

“…Global functional indices of the heart, e.g., myocardial mass, end-diastolic volume, end-systolic volume and ejection fraction, can be measured using CINE MRI [4][5][6][7]. Regional tissue viability can be assessed with perfusion MR, e.g., using arterial spin labeling techniques [8], or from the delayed enhancement effect following gadolinium diethylenetriamine penta-acetic acid (Gd-DTPA) injection [9].…”

In this paper we introduce an improved harmonic phase (HARP) analysis for complementary spatial modulation of magnetization (CSPAMM) tagging of the mouse left ventricular wall, which enables the determination of regional displacement fields with the same resolution as the corresponding CINE anatomical images. CINE MRI was used to measure global function, such as the ejection fraction. The method was tested on two healthy mouse hearts and two mouse hearts with a myocardial infarction, which was induced by a ligation of the left anterior descending coronary artery. We show that the regional displacement fields can be determined. The mean circumferential strain for the left ventricular wall of one of the healthy mice was −0.09 ± 0.04 (mean ± standard deviation), while for one of the infarcted mouse hearts strains of −0.02 ± 0.02 and −0.10 ± 0.03 were found in the infarcted and remote regions, respectively.
