Although higher magnetic field strength is a means to increase SNR in MRI, cardiac imaging has been difficult at high fields due to decreased RF penetration. Using a tailored cardiac coil constructed of two transmit surface coils with a four‐element multicoil for signal reception, the authors demonstrate high‐quality heart images acquired on a 4‐T scanner. These images show an increase in SNR of ∼2.5‐fold over imaging at 1.5 T. This improvement in image quality can be used to increase in‐plane resolution, reduce slice thickness, or reduce total scan time. Magn Reson Med 45:176–178, 2001. © 2001 Wiley‐Liss, Inc.
