Abstract

Magnetic resonance (MR) transverse relaxation time (T2) mapping has frequently been used to evaluate collagen content and its organization. In this study, T2 mapping, using novel three-dimensional-triple-echo-steady-state technique was performed in volunteers in-vivo at 7 Tesla under the static load applied by MR compatible compression device. We observed that load of 250 N applied for 12 minutes was sufficient for in-vivo evaluation of reversible cartilage compression effect. MRI associated with in-vivo compression of cartilage could therefore provide more insight into the mechanical properties of cartilage tissue.
