Measurement of T2 value by using 3.0T MRI for patient with ankle arthritis.

This study intended to evaluate shape of ankle joint cartilage and damage to the ankle joint cartilage by measuring changes in T2 value of cartilage of healthy people without ankle arthritis and patients with ankle arthritis. The multi-echo technique was used for 20 healthy persons who had no ankle arthritis in the past or in the present clinically and 20 patients who were examined to have ankle arthritis in order to obtain T2 map image of knee joint cartilage. We divided the talotibial joint into medial position, middle position and lateral position to calculate the mean values of T2 in 18 spots that included anterior part, middle part and posterior part of cartilage of neck bone and ankle bone. Mean T2 values were measured in the healthy people group and the ankle arthritis patient group. According to the measurement results, the mean T2 value of the ankle arthritis patient group was measured to be higher than that of the healthy people group.
