摘要.Multimodal fusion is an effective approach to better
understand brain disease. To date, most current fusion
approaches are unsupervised; there is need for a multivariate
method that can adopt prior information to guide multimodal
fusion. Here we proposed a novel supervised fusion model,
called “MCCAR+jICA”, which enables both identification of
multimodal co-alterations and linking the covarying brain
regions with a specific reference signal,
e.g., cognitive scores.
The proposed method has been validated on both simulated and
real human brain data. Features from 3 modalities (fMRI,
sMRI, dMRI) obtained from 147 schizophrenia patients and 147
age-matched healthy controls were included as fusion input,
who participated in the Function Biomedical Informatics
Research Network (FBIRN) Phase III study. Our aim was to
investigate the group co-alterations seen in three types of MRI
data that are also correlated with working memory
performance. One joint IC was found both significantly
group-discriminating (p=7.4E-06, 0.001, 7.0E-09) and highly
correlated with working memory scores(r=0.296, 0.241, 0.301)
and PANSS negative scores (r=-0.229, -0.276, -0.240) for fMRI,
dMRI and sMRI, respectively. Given the simulation and FBIRN
results, MCCAR+jICA is shown to be an effective multivariate
approach to extract accurate and stable multimodal components
associated with a particular measure of interest, and promises a
wide application in identifying potential neuromarkers for
mental disorders.
