Deep learning techniques for medical image analysis have reached comparable performance to medical experts, but the lack of reliable explainability leads to limited adoption in clinical routine. Explainable AI has emerged to address this issue, with causal generative techniques standing out by incorporating a causal perspective into deep learning models. However, their use cases have been limited to 2D images and tabulated data. To overcome this, we propose a novel method to expand a causal generative framework to handle volumetric 3D images, which was validated through analyzing the effect of brain aging using 40196 MRI datasets from the UK Biobank study. Our proposed technique paves the way for future 3D causal generative models in medical image analysis.
