We evaluated the MR imaging technique and analyzing methods of articular cartilage of the knee. T2 values of the cartilage are different in parts of the joint without any morphological abnormalities. The cartilage damage is more frequent and T2 values are also higher in the medial compartment than other compartments of the asymptomatic knee. This variation should be considered in analyzing the cartilage damage in rheumatoid arthritis and T2 ratio is useful to analyze the cartilage in different parts of the knee.
