T2 Measurements of Cartilage in Osteoarthritis Patients With Meniscal Tears

Abstract: OBJECTIVE. The objective of this study was to quantitatively assess cartilage degeneration via T2 mapping to compare patients with and those without meniscal tears. SUBJECTS AND METHODS. Thirty-seven patients (18 men, mean age ± SD, 65.7 ± 7.8 years; 19 women, mean age, 63.8 ± 12.0 years) with clinical symptoms of osteoarthritis were studied on 3-T MRI using a 2D multiecho spin-echo sequence for T2 mapping. Meniscal signal and morphology were qualitatively graded and correlated to the T2 values of cartilage.… Show more

“…The volunteers’ body height and weight were obtained to calculate the body mass index (BMI). Volunteers with a BMI >24.9 kg/m 2 were classified as overweight, and volunteers with a BMI >29.9 kg/m 2 were classified as obese (19). All the recruited volunteers provided written informed consent to participate in the study, which was approved by the local institutional review board.…”

“…147 In addition, higher and more heterogeneous cartilage T2 relaxation time has been noted in subjects with risk factors for osteoarthritis when compared with asymptomatic volunteers despite both groups of individuals having normal radiographs. 152,153 Associations between higher cartilage T2 relaxation time and the presence of cartilage lesions, 153 meniscus tears, 154 bone marrow edema lesions, 155 and knee pain 156 have been reported. Higher T2 relaxation time of articular cartilage has also been shown to predict the progression of focal cartilage lesions within the knee joint in longitudinal studies.…”

“…T 2 relaxation times are widely used as quantitative measures in clinical OA research to track cartilage degradation in the knee [4244], ankle [45, 46], and hip joints [47]. Natural spatial variation along the range of depths from the articular surface has been observed with T 2 relaxation times [48, 49].…”
