Impact of an endorectal coil for 1H-magnetic resonance spectroscopy of the prostate at 3.0Â T in comparison to 1.5Â T: Do we need an endorectal coil?

The ERC improves the diagnostic suitability and the SNR in MRSI at 3.0 T. Less voxels at 3.0 T with disabled ERC are suitable for diagnosis compared to 1.5 T with ERC. MRSI at 3.0 T with ERC shows the highest SNR. SNR in dorsal quadrants of the prostate was higher using ERC.
