Direct Use

This model is intended for use by healthcare organizations, researchers, and medical professionals to aid in the detection of brain tumors in MRI scans. It serves as a supportive tool for diagnosis, helping to streamline the review of large volumes of scans and potentially accelerating early detection.

Out-of-Scope Use

This model is not a substitute for professional medical diagnosis and should not be used as the sole basis for treatment decisions. It is designed as an assistive tool and should always be used alongside expert evaluation and additional diagnostic tests.

Bias, Risks, and Limitations

• The model’s accuracy may vary based on the diversity and quality of MRI scans provided. It is trained on specific imaging datasets and may have reduced performance on data from different sources or imaging equipment.
• Predictions are based on patterns in the training data and may not account for rare or atypical tumor presentations.
• While the model has high accuracy on the test set (95%), real-world accuracy may vary due to differences in clinical environments.

Recommendations

Users should:

• Use the model’s predictions in conjunction with comprehensive medical evaluation and diagnostic testing.
• Regularly update the model with diverse and representative MRI scan data.
• Be aware of the model's limitations and potential biases when interpreting results.

Training Data

The model was trained on a dataset of brain MRI scans that included labeled data indicating the presence or absence of brain tumors.

Training Hyperparameters

• Training regime: Full precision (fp32)
• Framework: Keras
• Language: Python

Testing Data

The model was validated on a separate portion of the MRI dataset to evaluate its performance on unseen cases.

Metrics

• Accuracy: 95%

Model Architecture and Objective

The model employs a Convolutional Neural Network (CNN) architecture implemented in Keras. Its objective is to detect the presence of brain tumors in MRI images.
