+ # SimCLR-MRI Pre-trained Encoder (Base)
16
+
17
+ This repository contains a pre-trained 3D CNN encoder for MRI analysis. The model was trained using contrastive learning (SimCLR) on MPRAGE brain MRI scans, using standard image augmentations.
18
+
19
+ ## Model Description
20
+
21
+ The encoder is a 3D CNN with 5 convolutional blocks (64, 128, 256, 512, 768 channels), outputting 768-dimensional features. This base variant was trained on real MPRAGE scans using standard contrastive augmentations (random rotations, flips, intensity changes).
22
+
23
+ ### Training Procedure
24
+ - **Pre-training Data**: 51 qMRI datasets (22 healthy, 29 stroke subjects)
25
+ - **Augmentations**: Standard geometric and intensity transformations
26
+ - **Input**: 3D MPRAGE volumes (96×96×96)
27
+ - **Output**: 768-dimensional feature vectors
28
+
29
+ ## Intended Uses
30
+
31
+ This encoder is particularly suited for:
32
+ - Transfer learning on T1-weighted MRI tasks
33
+ - Feature extraction for structural MRI analysis
34
+ - General brain MRI representation learning
