Embodiment Construction
[0078] The present invention aims to propose a method for constructing an individualized prediction model of first-episode schizophrenia, and solve the problem of low accuracy in the auxiliary diagnosis of the existing SCH brain structure network model. Its core idea is: obtain the single-shot echo-planar imaging of the diffusion tensor of patients with first-episode schizophrenia; preprocess the diffusion tensor image; construct a sparse brain structure network based on the preprocessed image; use similar network fusion method, Construct a sparse multi-threshold structure network for each subject; extract topological attribute features based on the processed fusion multi-threshold brain structure network, perform classification training after feature screening, and obtain an individualized prediction model for first-episode schizophrenia. Performance validation evaluation of an individualized prediction model for first-episode schizophrenia.
