Volumetric Dynamic Imaging for Functional Kinematic Assessment of the Wrist

Dynamic MRI can be useful for evaluation of wrist instability. However, most available real-time MRI methods are either limited due to their 2D nature or provide only low temporal resolution and insufficient image quality. Here, we propose a novel approach for volumetric dynamic wrist examination by assembling 2D real-time data into 3D snapshots using MRI-visible markers. The method has been demonstrated for ulnar-radial deviation using a flexible wrist coil and 3D-printed support platform for guiding motion. Future work will use a high-resolution static MRI as morphological prior to segment bones on the dynamic volumes and allow for quantitative kinematic assessment.
