Magnetic resonance imaging (MRI) is widely used for the
diagnosis of brain tumour. However, it failed to provide
information of metabolism. Magnetic resonance
spectroscopy imaging (MRSI) has shown great potentials
to reveal the tumour heterogeneity, yet, with relatively
poor resolution. The current study developed an
unsupervised data fusion method for brain abnormality
diagnosis. The accurate tissue sources from MRSI and the
high resolution spatial distribution from MRI can be
integrated and differentiated by using non-negative
matrix factorization. The in vivo experiments on
patients with brain tumour of low grade glioma and
glioblastoma multiforme demonstrated successful fusion
between MRSI data and MRI in brain tumour.
