“…This observation holds true for both unselected patients and patients in sinus rhythm. MRI has been shown to have a close correlation to anatomic models (29) and a better reproducibility (23, 30, 31) than standard 2D‐echo (6, 18, 19, 32). Furthermore, the lower inter‐observer, inter‐study, and intra‐study variability of MRI as compared to 2D‐echo has been demonstrated for normal subjects and for patients with different cardiac diseases (23, 29, 33–36), but not yet for patients with DCM.…”

Studies on medical therapy in heart failure are focused on changes of left ventricular (LV) dimensions and function. These changes may be small, requiring a large study group. We measured LV parameters (LV volumes, LV ejection fraction (LV-EF), and left ventricular mass (LVM)) with two-dimensional echocardiography (2D-echo) and magnetic resonance imaging (MRI) in 50 patients. Based on the difference between the measurements, we determined the variance of the results and calculated the sample sizes needed to detect changes of baseline values. For the calculated and measured parameters we found significant differences between the two techniques: LV-EF and LVM were higher in 2D-echo, and LV dimensions were comparable. The sample size to detect relevant changes from baseline with MRI was significantly (P < 0.01) smaller than in 2D-echo. We conclude that MRI is su- Index terms: magnetic resonance imaging; echocardiography; heart failure; left ventricular function; sample size Abbreviations: MRI ϭ magnetic resonance imaging, DCM ϭ dilated cardiomyopathy, 2D-echo ϭ two-dimensional echocardiography, LV ϭ left ventricular, LV-EF ϭ left ventricular ejection fraction, LVM ϭ left ventricular mass, LV-EDD ϭ left ventricular end-diastolic dimension (measured in short axis orientation at papillary muscle tip level), LV-PW ϭ left ventricular posterior wall thickness at end-diastole.

“…by angiotensin‐converting‐enzyme‐inhibitors (2). Improvements of LV dimensions and function achieved with these drugs do not exceed 10% to 15% of baseline levels (6, 7–10). Most cardiovascular intervention trials focus on LV‐EF (7, 8), LVM (9–11), or LV dimensions (12), and use standard imaging methods, such as 2D‐echo, for patient follow‐up.…”

“…THE PROGNOSTIC AND THERAPEUTIC implications of both single and serial assessment of cardiac volumes, mass, and function are now well established in a variety of cardiac diseases (1–6). Cardiovascular magnetic resonance (CMR) provides an accurate and reproducible assessment of cardiac structure and function through the acquisition of tomographic images of high spatial and temporal resolution.…”

Cardiovascular magnetic resonance (CMR) is the reference standard for the assessment of cardiac function. Faster sequences, such as breath‐hold (BH) fast low‐angle shot, have made CMR more clinically acceptable and cost effective. In a significantly large patient group, however, holding their breath is difficult, resulting in poor‐quality images. We compared prospective navigator‐echo respiratory gating (NE), which allows image acquisition during free breathing, and BH imaging in 14 patients with heart failure and 10 normal volunteers. There was good agreement between both NE and BH volumes, mass, and ejection fraction. The image quality of both NE basal and apical slices was significantly better than the corresponding BH slices in both the heart failure (P < 0.01) and normal groups (P < 0.05). The NE image acquisition was more time efficient than the BH acquisition in the heart failure group (P < 0.01), with no difference in the normal group (P = 0.2). Thus, prospective navigator‐echo gating, previously only described in coronary artery imaging, can be used in the assessment of cardiac function. It is particularly useful in patients who find it difficult to hold their breath in whom NE provides good‐quality, time‐efficient images. J. Magn. Reson.
