- Fig 1.
360 MHz 1H MR spectra of head and neck tumors (A) control (B) failed case. Both specimens came from oral tongue tumors. Chos, choline-containing compounds; Cr, creatines; Gln, glutamine; Glu, glutamic acid; HOD, deuteriated water; Lac, lactic acid; Leu, leucine; Lip, lipid; Tau, taurine; Val, valine. Assignments do not imply that these are the only substances contributing to a particular peak.

Bar graphs of the 3.2/3.0 spectral intensity ratio (mean ± SEM). Dark shade, control; light shade, failed cases; A, tumors from all sites included; B, tumors of the tongue only.
- Fig 3.
Bar graphs of the 1.3/0.9 spectral intensity ratio (mean ± SEM). Dark shade, control; light shade, failed cases; A, tumors from all sites included; B, tumors of the larynx only.
