Regionally resolved cardiac metabolism using a dipole‐loop array coil for <scp> 7 T <sup>31</sup> P </scp> ‐ <scp>MRSI</scp>
Dipole-loop array coils present a promising new approach for human cardiac <sup>31</sup>P-MRSI at 7 T. Their favorable B<sub>1</sub> <sup>+</sup> uniformity at depth and specific absorption rate over loop arrays and improved SNR when combined with loops for reception could be beneficial for further clinical studies measuring energetics by <sup>31</sup>P-MRSI at 7 T. The new capability to assess PCr/γATP ratios across the whole left ventricle could enable clinical studies to investigate regional changes in cardiac energetics for the first time.
