Background:

Accurate segmentation of multiple sclerosis (MS) lesions in 3D MRI is critical for patient care.
Challenges include lesion subtlety, heterogeneity, and annotation difficulties.

Purpose of the Study:

To develop an improved deep learning framework for automated MS lesion segmentation.
To enhance volumetric segmentation performance across multi-modal MRI sequences.

Main Methods:

Proposed Efficient-Net3D-UNet, integrating MBConv3D blocks and lesion-aware patch sampling.
Evaluated against a conventional 3D U-Net baseline.
Utilized Dice similarity coefficient, precision, recall, accuracy, and specificity for assessment.

Main Results:

EfficientNet3D-UNet achieved a Dice score of 48.39%, outperforming the baseline 3D U-Net (31.28%).
EfficientNet3D-UNet demonstrated higher precision (49.76%) and recall (55.41%).
The proposed model showed faster convergence and reduced overfitting.

Conclusions:

Efficient-Net3D-UNet presents a robust and computationally efficient solution for MS lesion segmentation.
The model shows promise for real-world clinical applications in automated diagnosis and monitoring.
