ABSTRACT:
A technique is disclosed for the detection of cancer using nuclear magnetic resonance (NMR). Specifically, NMR parameters for protons of lipid methyl and/or methylene groups are determined and compared against a corresponding value for healthy patients. In the preferred embodiments, an NMR spectrometer is employed in conjunction with a Fourier transformer to provide a spectrum for non-water components of blood, blood serum or blood plasma and the width of the methyl and/or methylene groups is measured at half-height as a determination of spin-spin relaxation time (T.sub.2) which is the parameter used for purposes of comparison with healthy controls. Suppression of the water proton signal is employed where necessary in order to obtain a suitable spectrum for the non-water component protons.
