Coronary magnetic resonance angiography: in vivo comparison of image quality at 1.5 Tesla versus 3.0 Tesla with Parallel Radiofrequency Transmission
نویسندگان
چکیده
Coronary plaque and thrombus characterization at 3.0 Tesla holds great potential for clinical benefit but problems still exist with coronary lumen image quality at 3.0 Tesla, which is a pre-requisite for these techniques. This study shows that despite implementation of parallel transmit technology to improve radiofrequency (B1 field) homogeneity, balanced steady-state-free-precession (b-SSFP) Coronary Magnetic Resonance Angiography (CMRA) at 3.0 Tesla is still inferior to 1.5 Tesla imaging. Parallel transmit will need to be combined with other recent technological advances to achieve superior imaging at 3.0 Tesla.

Spiral magnetic resonance coronary angiography--direct comparison of 1.5 Tesla vs. 3 Tesla.
BACKGROUND MR coronary angiography (MRCA) has been demonstrated successfully at 3 Tesla (T). However, the advantages remain unclear. No systematic comparison of MRCA between 1.5 T and 3 T has been performed. Therefore, anatomic coverage, image quality, signal-to-noise ratio (SNR), contrast-to-noise ration (CNR), and susceptibility artifacts were compared in 23 subjects. METHODS AND RESULTS Id...
متن کاملBreath-hold imaging of the coronary arteries using quiescent-interval slice-selective (qiss) magnetic resonance angiography - pilot study at 1.5 tesla and 3 tesla
BACKGROUND Coronary magnetic resonance angiography (MRA) is usually obtained with a free-breathing navigator-gated 3D acquisition. Our aim was to develop an alternative breath-hold approach that would allow the coronary arteries to be evaluated in a much shorter time and without risk of degradation by respiratory motion artifacts. For this purpose, we implemented a breath-hold, non-contrast-enh...

متن کاملCardiac magnetic resonance adenosine perfusion at 3 Tesla is superior to 1.5 Tesla for detection of relevant coronary artery stenosis
Background Cardiac magnetic resonance imaging (CMR) including adenosine perfusion and late gadolinium enhancement (LGE) at 1.5 Tesla (T) has been established for noninvasive detection of relevant coronary artery disease (CAD). However, little is known about the potential advantages of 3.0-T to detect CAD. The aim of our prospective study was to compare a compiled clinical routine CMR protocol p...
