Abstract

A methodology for imaging cadaver and patient joints using magnetic resonance imaging (MRI) is validated using a knee cadaver joint, three shoulder cadaver joints and the shoulder of a volunteer patient. High contrasting cartilage images were obtained using a GE Signa 1.5 T MRI machine. Geometric models for the articular surfaces were created from the contour curves using parametric bicubic B-spline representations. Contact areas between these models were determined by the proximity method to fall within normative ranges. Cadaver and patient MRIs demonstrated the same clarity of cartilage delineation, indicating that motion artifacts maybe easily avoided within patient populations.
