FWHM of water and metabolite resonances using endorectal and external body array “receive” coils.

Peak	Endorectal FWHM Mean ± SD	CV (%)	External body array FWHM Mean ± SD	CV (%)
Cancer Cit	11.73 ± 2.75	23.41	15.45 ± 6.17	39.96
Cancer (Cr+Ch)	17.71 ± 6.78	27.57	25.75 ± 8.47	32.88
Non-cancer Cit	11.53 ± 1.73	15.02	18.83 ± 10.16	53.94
Non-cancer (Cr+Ch)	19.59 ± 6.83	27.77	28.06 ± 10.80	38.49
Water	25.00 ± 5.16	20.64	31.00 ± 9.62	31.05

Note: The FWHM of the water resonance represents global line width whereas the FWHM values of metabolites were derived from spectra extracted from selected locations.
