Abstract
Abstract Current limitations of coronary magnetic resonance angiography
(MRA) include a suboptimal signal-to-noise ratio (SNR), which limits
spatial resolution and the ability to visualize distal and branch
vessel coronary segments. Improved SNR is expected at higher field
strengths, which may provide improved spatial resolution. However,
a number of potential adverse effects on image quality have been
reported at higher field strengths. The limited availability of high-field
systems equipped with cardiac-specific hardware and software has
previously precluded successful in vivo human high-field coronary
MRA data acquisition. In the present study we investigated the feasibility
of human coronary MRA at 3.0T in vivo. The first results obtained
in nine healthy adult subjects are presented. Magn Reson Med 48:425–429,
