This directory contains a tutorial demonstrating how to use MONAI for 3D regression tasks, specifically brain age prediction using the IXI dataset and a DenseNet3D architecture.

The densenet_training_array.ipynb notebook provides an end-to-end example of:

• Loading and preprocessing 3D brain MRI data
• Setting up data transforms for regression tasks
• Training a DenseNet3D model for age prediction
• Evaluating model performance on test data

This notebook can be run locally with Jupyter or in Google Colab. The notebook includes all necessary setup instructions and dependency installations.
