Accurate brain function area mapping plays a vital role in preoperative planning.
Yang Wang
The purpose of this study is to use resting state functional magnetic resonance imaging (rs-fMRI) data to evaluate the effectiveness of neural network (NN) methods in predicting preoperative motor zone positioning.
Methods 109 patients with craniocerebral tumors underwent rs-fMRI and fMRI (TbfMRI) scan based on hand movement tasks.

A neural network based on individual resting fMRI (RsfMRI) features and a healthy control group task fMRI activation map was used to train 20 models.
Compared with the MAP derived by ICA, the CC matrix of the MAP predicted by the neural network shows a higher diagonal value (p<0.
Regardless of whether there is movement disorder, DC NN_Act is higher than DC ICA_Act (P<0.
The neural network method can predict individual motor activation based on rs-fMRI data, and has a good clinical application prospect in patients with brain tumor anatomy and functional reconstruction.
