“…They were regarded as meaningful brain areas and used as ROIs in the functional connectivity analysisDefault-mode network, salience network | The two dataset were from two different imaging platforms | Pläschke, 201741 | rs-fMRI | 170 subjects: -86 SCZ -84 HC | SVM | 61–72% | Sn 65–77% Sp 46–69% AUC 0.61–0.79 | Authors investigated 12 functional networks. Only meta-analytic networks with a minimum of 10 nodes were included, since a lower number of features are uninformative for robust classification | Emotion-processing, empathy and cognitive action control networks | Young-old classification was based on all networks and outperformed clinical classification |
Liu, 201842 | rs-fMRI | 79 subjects: −48 Drug-Naïve FES AOS -31 HC | SVM VMHC | 94.93% | Sn 100% Sp 87.09% | For each subject, the fMRI scan lasted for 480 s, and 240 volumes were obtained. The first 10 volumes of each subject were discarded to certain steady-state conditions and for participants to acclimatize to a scanning environment during the analyzed portion of the data | Fusiform gyrus, superior temporal gyrus, insula, precentral gyrus and precuneus | authors also used a battery of neurocognitive tests and they demonstrated deficits in multiple cognitive functions in patients |
Zeng, 201846 | rs-fMRI 1.5-3T | 734 subjects: -357 SCZ -377 HC | RFE-SVM RFE-LDA SAN DANS | 81–85% | Sn 75–83% Sp 81–86% | Authors used multi-atlas based whole-brain fcMRI in the MVPA, which measures functional connectivity of the same image in different spaces. The three atlases used included 176, 160 and 116 ROIs respectively | Cortical-striatal-cerebellar circuit (default, salience, frontoparietal control, ventral attention, dorsal attention and somatomotor, visual). | This paper provides for a multi-variate based whole-brain fcMRI pattern analysis to ensure the optimal use of the wealth of information present in fcMRI scans. |
Amin, 201847 | fMRI 3T T2-weighted | 298 subjects: -144 SCZ -154 HC | Translation-based multimodal fusion approach | N.A. | N.A. | dFNC as the functional features and ICA-based sources from grey matter densities as the structural features | Putamen, insular, precuneus, posterior cingulate cortex and temporal cortex | The deep learning approach has a potential for learning dynamic features from the fMRI data, and thus can offer a favorable framework for multimod... |
