In prostate MRI at 7T, use of endorectal coils (ERCs)
can improve the signal-to-noise ratio (SNR) more than
4-fold compared to using an external surface array
(ESA). Here, we compare the SNR and transmit performance
(B1+) of three different 2-channel ERC coil geometries
(two loops, ERC-2OL; stripline-large loop, ERC-SLL;
stripline-small loop, ERC-SSL) inside a uniform
torso-sized phantom. ERC-SSL performed the best among
the ERCs. SNR and B1+ of ERC-SSL compared to a
16-channel ESA has improved ~5.6-fold and ~6.9-fold,
respectively. Reusable, rigid, multi-channel ERCs are a
valuable tool in imaging the prostate at 7T.
