Abstract
Proteoglycan deficiency in articular cartilage is diagnosed based on quantified signal intensities of pixels of a magnetic resonance image (MRI) extending across a depth of the articular cartilage. A pattern of the thus quantified signal intensities is indicative of proteoglycan distribution across the cartilage depth.
