Abstract
Pattern recognition has been applied to the analysis of in vivo P-31 N MR spectra. Using four different classes of tumour and three types of normal tissue, cluster analysis and artificial neural networks were su ccessful in separating and classifying the majority of samples analyse d. Although the phosphomonoester and P(i) regions appeared to be the m ost important spectral features, data representing the entire P-31 spe ctrum were required for best separation of the tumour and tissue class es.
