Abstract

Accelerated “whole‐heart” coronary imaging with sensitivity encoding applied in both phase encoding directions (2D‐SENSE) was investigated. In order to maximize the signal‐to‐noise ratio (SNR), coil configuration optimization was performed. To this end, 10 practical coil configurations each consisting of six standard coil elements were investigated and the local SNR was assessed by means of phantom experiments. Based on the experimental data, a symmetric configuration was found to yield the highest SNR. In a volunteer study, 2D‐SENSE coronary images were obtained with total reduction factors of 3 and 4. Excellent depiction of the right and left coronary systems was possible in all cases. Magn Reson Med, 2006. © 2006 Wiley‐Liss, Inc.
