Arxiv URL: Enhancing Wrist Fracture Detection with YOLO

The proposed project aims to provide a solution to the scarcity of radiologists and the lack of specialized training among medical professionals in diagnosing and treating wrist abnormalities in children, adolescents, and young adults. With the incidence rate of distal radius and ulna fractures being higher during puberty, timely and accurate diagnosis is crucial. To address this, the project aims to provide an automated system using object detection algorithms and computer vision and machine learning techniques, enabling users to easily input pediatric wrist X-ray images and receive an output indicating the presence and location of any anomalies. The system is designed to be user-friendly, providing high accuracy and precision in diagnosis, and accessible through a mobile application without an internet connection. The project aims to reduce the dependency on manual interpretation of X-ray images, which can be time-consuming and subject to errors, and to make the diagnostic process more efficient for both patients and doctors. The research paper further highlights the effectiveness of single-stage deep neural network-based detection models, specifically YOLOv8x, in enhancing pediatric wrist imaging, with a fracture detection mean average precision (mAP) of 0.95 and an overall mAP of 0.77 on the GRAZPEDWRI-DX pediatric wrist dataset. In summary, the project aims to provide an innovative and efficient solution to improve the diagnosis and treatment of wrist abnormalities, ultimately improving patient care and convenience.

Installation

To run this machine learning project on Flask, you need to follow these steps:

  1. Clone the project repository from GitHub:
git clone https://github.com/ammarlodhi255/pediatric_wrist_abnormality_detection-end-to-end-implementation.git
  1. Navigate to the project directory:
cd pediatric_wrist_abnormality_detection-end-to-end-implementation
  1. Create a virtual environment for the project:
python3 -m venv env
  1. Activate the virtual environment:
source env/bin/activate
  1. Install the required packages using pip:
pip install -r requirements.txt
  1. Export the Flask app:
export FLASK_APP=app.py
  1. Run the Flask app:
flask run

The app should now be running on your local machine. You can access it by opening a web browser and navigating to http://localhost:5000.

Results

We conducted a total of 23 detection procedures using different variants of each YOLO model and a two-stage detection model (Faster R-CNN) on a test set consisting of 1016 randomly selected samples. The performance of each model was evaluated using metrics such as precision, recall, and mean average precision (mAP).

Below are the weights of the YOLOv8 model along with their corresponding results:

YOLOv8 Weights

Model variants size
(pixels)		 Precision Recall [email protected] [email protected]:0.95
YOLOv8n 640 0.73 0.58 0.59 0.36
YOLOv8s 640 0.72 0.63 0.65 0.39
YOLOv8m 640 0.60 0.60 0.56 0.36
YOLOv8l 640 0.74 0.60 0.62 0.41
YOLOv8x 640 0.79 0.64 0.77 0.53

Presented below is a summary of the mean average precision (mAP) scores achieved by all YOLO variants and Faster R-CNN, for both the fracture class and all classes combined.
