Osteoarthritis(OA)of the knee joint is a degenerative disease characterized by primary pathological changes in cartilage,with joint pain,swelling,and restricted movement as its main clinical symptoms,significantly impacting the quality of life for affected individuals.Magnetic resonance imaging(MRI)serves as the primary diagnostic tool for as-sessing OA cartilage degeneration.It not only detects morphological changes in cartilage but also,with the recent develop-ment of quantitative imaging techniques,evaluates alterations in the biochemical composition of cartilage.This article re-views and summarizes the research progress in MRI quantitative imaging techniques for the early diagnosis of cartilage de-generation and injury.
