Retrospective analysis of multi-parametric MRI identifies 2.5D deep learning improves brain metastases classification accuracy.

The 2.5D model achieved an accuracy of 0.906 and AUC of 0.961 in classifying brain metastases.
In contrast, the 2D model's performance was lower, with an accuracy of 0.660 and AUC of 0.686.
Using convolutional neural networks, features were extracted from slices of multiparametric MRI data.
This study indicates that 2.5D deep learning methods may enhance the diagnostic capability for identifying brain metastases.

Zhu et al. (2025) studied this question.
