Preliminary report on in vivo coronary MRA at 3 Tesla in humans
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 improv...

| description | 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.
