This study demonstrates a feasibility of texture analysis based on T2 and T1ρ mapping of the meniscus. Some of the investigated texture features showed statistically significant differences for both the medial and lateral meniscus between normal volunteers and patients with osteoarthritic knees. One particular texture feature (contrast) based on T2 was also able to differentiate patients with advanced from early knee osteoarthritis for the lateral meniscus as well. The results in this study demonstrate an alternative analytical approach based on texture features as surrogate variables for the evaluation of meniscus properties using T2 and T1ρ mapping.
