A susceptibility matched endorectal coil was tested and compared against a classical endorectal coil design. For different phantom angulations, it enabled a significant decrease (~30%) of the FWHM of spectra acquired on in vitro NMR tubes. These promising results and the restricted FWHM observed suggest the interest of this new coil for the acquisition of in vivo spectra especially for the characterization of the colorectal cancer.
