IIT Guwahati Researchers Develop Model to Predict Knee Osteoarthritis from X-Ray Images

New Delhi: Researchers from the Indian Institute of Technology (IIT) Guwahati have developed a model which will be able to detect Knee Osteoarthritis severity using X-rays images.

The AI-based model named ‘OsteoHRNet’, has been developed by Rohit Kumar Jain, an MTech (data science) graduate, under the joint supervision of Arijit Sur and Palash Ghosh of computer science and engineering, and mathematics departments, respectively, IIT Guwahati. The research team also includes Prasen Kumar Sharma and Sibaji Gaj, both former PhD students of Sur.

Knee osteoarthritis, an IIT Guwahati statement said, is the most common musculoskeletal disorder in the world and has a prevalence of 28% in the country. There is no possible cure for knee OA except total joint replacement at an advanced stage hence an early diagnosis is essential for pain management and behavioral corrections, it added.

According to the press release by the institute, MRI and CT scans provide a 3D image of the knee joints for effective diagnosis of knee OA but their availability is limited and expensive, the statement added that for routine diagnosis X-ray imaging is very effective and more economically feasible.

Ghosh said, “Compared to other techniques, our model can pinpoint the area, which is medically most important to decide the severity level of knee OA thus helping medical practitioners to detect the disease accurately at an early stage.”

The developed model uses deep convolutional neural networks (CNN) i.e an algorithm from image recognition. The severity of Knee Osteoarthritis is measured according to the World Health Organisation approved Kellgren and Lawrence (KL) grading scale.

It is built upon a high-resolution network (HRNet), to capture the multiscale features of knee X-rays.

Sur said, “Although simple, the proposed model may be a good starting point for analyzing inexpensive radiographic modalities such as X-rays. Our group is currently focusing on how efficient deep learning-based models can be designed so that we can work on inexpensive and easily available modalities such as very low-resolution radiographic images or even photos taken from radiographic plates by a smartphone.”

The team is further working to reconfigure these models so that they can be deployed in resource-constrained devices.
