New paper: Interleaved 23Na/1H MRI of the human heart at 7 T using a combined 23Na/1H coil setup and 1H parallel transmission
Congratulations to Laurent Ruck and co-authors on the recently published article ‘Interleaved 23Na/1H MRI of the human heart at 7 T using a combined 23Na/1H coil setup and 1H parallel transmission’!
This study investigated the application of interleaved 23Na/1H MRI at 7 T using parallel excitation pulses (pTx) at 1H for cardiac imaging and a combined setup of a 23Na volume coil and two 1H transmit/receive arrays. The results show that the combination of the coils slightly reduced the 23Na transmit efficiency and the signal-to-noise ratio, while the 1H transmit efficiency was hardly affected. This method had no significant impact on image quality, while individual 1H-pTx pulses significantly improved the B1+ homogeneity of 1H in the myocardium. The method enables efficient and homogeneous excitation for cardiac imaging and holds promise for robust quantification of the tissue sodium concentration in myocardial tissue.
