Diagnostic accuracy of 1.5-T unenhanced whole-heart coronary MR angiography performed with 32-channel cardiac coils: initial single-center experience.
PURPOSE To compare the imaging time and image quality obtained with whole-heart coronary magnetic resonance (MR) angiography performed with five- and 32-channel coils in healthy subjects and determine the accuracy of MR angiography performed with 32-channel coils in the detection of obstructive coronary artery disease (CAD). MATERIALS AND METHODS The institutional review board approved the st...
متن کامل3.0T whole-heart coronary magnetic resonance angiography performed with 32-channel cardiac coils: a single-center experience.
BACKGROUND Whole-heart coronary magnetic resonance angiography (MRA) is a promising method for noninvasive, radiation-free detection and exclusion of obstructive coronary artery disease; however, the required imaging time and robustness of the technique are not yet satisfactory. We evaluated the value of whole-heart coronary MRA at 3.0T using a 32-channel cardiac coil, which reduces image-acqui...
متن کاملWhole heart coronary MRA at 3.0T: a comparison between multi and single- RF transmission
Introduction On high field MRI scanners uniform radio frequency (RF) excitation over the entire field-of-view is often challenging with single-channel RF transmit coils. This may cause a reduction of image quality (e.g. shadowing artifacts). This problem is most pronounced in sequences which heavily rely on a homogenous magnetic field, such as steady state free precession (SSFP) sequences, desp...
متن کاملDiagnostic Accuracy of Different Image Postprocessing Methods for the Detection of Coronary Artery Stenoses by Using Contrast Enhanced Coronary MRA at 3.0T
Introduction: Contrast enhanced 3T whole heart coronary MR angiography (CMRA) is a reliable method for the detection and exclusion of hemodynamically significant coronary stenosis and has shown high accuracy in recent single center trial. Whole heart coronary MR angiography has been introduced as a method that can provide visualization of long segments of all coronary arteries with a single 3D ...
متن کامل3T Contrast-Enhanced Whole Heart Coronary MRA using 32-Channel Cardiac Coils for the Detection of Coronary Artery Disease
Introduction: The development of contrast enhanced whole heart coronary MR angiography (CMRA) at 3T has shown promising results in clinical studies for the detection of significant coronary artery stenoses. However, the imaging time (~ 9 minutes) and spatial resolution (1.3 × 1.3 × 1.3 mm) remain major limitations. Newly available 32-channel cardiac coils allow greater acceleration factors, and...
