Cardiac MRI continues to develop and advance. MRI accurately depicts cardiac structure,
function, perfusion, and myocardial viability with an overall capacity unmatched by any other …

Magnetic resonance angiography (MRA) has excited the interest of many physicians
working in cardiovascular disease because of its ability to noninvasively visualize vascular …

Respiratory motion is a major limiting factor in improving image resolution and signal‐to‐
noise ratio in MR coronary imaging. In this work the effects of respiration on the cardiac …

Background—We investigated the applicability and image quality of contrast-enhanced
coronary artery visualization by multislice spiral CT using retrospective ECG gating. Methods …

A method and system for physiological gating is disclosed. A method and system for
detecting and predictably estimating regular cycles of physiological activity or movements is …

PURPOSE: To test the hypothesis that respiration effects in three-dimensional (3D) coronary
magnetic resonance (MR) imaging can be reduced with navigator-echo-based gating or …

PURPOSE: To determine the potential benefit of prospective navigator correction of image
position for coronary magnetic resonance (MR) angiography. MATERIALS AND METHODS …

Background The clinical significance of anomalously originating coronary arteries depends
on their proximal course. Diagnosis of this course by conventional x-ray coronary …

PURPOSE: To measure the duration of the rest period in the cardiac cycle, a parameter vital
to data acquisition in coronary magnetic resonance (MR) angiography. MATERIALS AND …

Currently, breath-holding during MR coronary angiography is used to minimize respiratory
motion. This technique requires patient cooperation and is associated with slice registration …
