Abstract：Objective To summarize the imaging features of degenerative knee osteoarthritis during the scanning process of low-field MRI and explore the clinical value of low-field MRI in diagnosing degenerative knee osteoarthritis. Methods The low-field MRI images of 70 patients who were confirmed as knee degenerative osteoarthritis by surgeries from January 2011 to December 2013 were retrospectively analyzed. Results The MRI images could clearly show the lesions of cartilago articularis, synovialis, meniscus and sclerotin as well as arthroedema, which indicated that low-field MRI had obvious advantages over traditional X-ray. Conclusion Low-field MRI which can accurately display the degree of degenerative knee osteoarthritis plays an important role in diagnosing degenerative knee osteoarthritis.
