Theoretical B₁ field distribution through the transverse planes centered at the ROI used for the calculation of SNR of different coils.

<p>The value of SNR was obtained when the mean B₁ value within the ROI was 1.957 μT. The SNR of body coil was normalized to 1 within the ROI for the transverse plane of body coil (a). The SNR of the transverse plane of phased array coil was 2.8387 (b). The results showed that the SNR of the phase array coil is higher than that of the body coil.</p

Detailed scanning protocols of hepatic MRS.

<p>RT = respiratory triggering; ★ the first spectroscopy sequence (phased array coil was used as the receiver) was “copied” for the second acquisition (body coil was used as the receiver) to produce identical voxel positioning.</p

The group using phase array coil demonstrated better SNR.
