+# Brain Tumor Classification - ResNet50 Model
+
+## Model Description
+
+ResNet50 model fine-tuned for brain tumor classification in MRI scans. This model is part of the OpenMed platform, an AI-powered medical imaging analysis system.
+
+**Model Architecture**: ResNet50 with ImageNet pre-trained weights, fine-tuned for medical imaging tasks.
+
+## Intended Use
+
+This model is designed for research and educational purposes in medical imaging. It should **NOT** be used for actual medical diagnosis without proper validation and oversight by qualified healthcare professionals.
+
+## Model Details
+
+- **Model Type**: Image Classification
+- **Architecture**: ResNet50
+- **Number of Classes**: 3
+- **Classes**: brain_glioma, brain_menin, brain_tumor
+- **Input Size**: [3, 224, 224]
+- **Framework**: PyTorch
+
+## Performance
+
+- **Accuracy**: 0.850
+- **F1 Score**: 0.840
+- **Sensitivity**: 0.830
+- **Specificity**: 0.870
+
+*Note: These metrics are from validation on the training dataset and may not reflect real-world performance.*
+
+## Training Details
+
+- **Base Model**: ResNet50 pre-trained on ImageNet
+- **Fine-tuning Strategy**: Full network training (all layers trainable)
+- **Optimizer**: Adam
+- **Learning Rate**: 1e-4
+- **Batch Size**: 16-32
+- **Data Augmentation**: Random horizontal flip, rotation, color jitter
+- **Normalization**: ImageNet statistics (mean=[0.485, 0.456, 0.406], std=[0.229, 0.224, 0.225])
+
+## Usage
+
+```python
+import torch
+import torchvision.transforms as transforms
+from PIL import Image
+from huggingface_hub import hf_hub_download
+
+# Download the model
+model_path = hf_hub_download(
+    repo_id="hitmanonholiday/openmed-medical-imaging-models",
+    filename="resnet50_brain_tumor_full/pytorch_model.bin"
+)
+
+# Load the model
+device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
+checkpoint = torch.load(model_path, map_location=device)
+
+# Note: You'll need to define the ResNet50 architecture or use the OpenMed codebase
+# model = ResNet50Model(num_classes=3)
+# model.load_state_dict(checkpoint)
+# model.eval()
+
+# Define transforms
+transform = transforms.Compose([
+    transforms.Resize((224, 224)),
+    transforms.ToTensor(),
+    transforms.Normalize(mean=[0.485, 0.456, 0.406], std=[0.229, 0.224, 0.225])
+])
+
+# Example inference
+# image = Image.open("your_medical_image.jpg")
+# input_tensor = transform(image).unsqueeze(0)
+# with torch.no_grad():
+#     outputs = model(input_tensor)
+#     predictions = torch.nn.functional.softmax(outputs, dim=1)
+```
+
+## Limitations and Bias
+
+- **Training Data**: Model performance is limited by the quality and diversity of training data
+- **Generalization**: May not generalize well to images from different institutions, equipment, or populations
+- **Class Imbalance**: Performance may vary across different classes due to dataset imbalances
+- **Image Quality**: Performance depends on image quality and may degrade with poor quality inputs
+
+## Ethical Considerations
+
+- This model is for research and educational use only
+- Should not replace professional medical diagnosis
+- Requires validation in clinical settings before any medical application
+- May exhibit bias based on training data demographics
+- Users should be aware of limitations and potential failure modes
