High resolution MRI of Trabecular Bone

Purpose: To evaluate the feasibility of in vivo isotropic high-resolution MR imaging of trabecular bone of the wrist at 3 Tesla. Method and materials: High-resolution 3D-MR imaging of the wrist was performed with a whole-body 3 Tesla MR scanner (TRIO, Siemens, Erlangen, Germany) and a dedicated transmit-receive wrist-coil. A heavily T2-weighted FISP (fast-imaging with steady precision) -3D sequence was applied (isotropic spatial resolution: 0.3mm, TR: 15 ms, TE: 7.51 ms, Flip angle: 25 deg). Up to now six healthy volunteers were examined in prone position and with forward-lifted arm. Measurement time was 7:51 mi…
