Abstract/Description of Original Work

Arthroplasty is the process by which a damaged joint in the human body is repaired or replaced by non-magnetic metallic implants. Areas of repair include the knees, the hips and the shoulders. It involves the insertion of a metal ball to replace the joint and a plastic socket to fit to the bone for growth and acclimatization. Despite recent advances in arthroplasty technology, implants fail over time leading to pain, discomfort and possible further injury in patients. Diagnosing areas of failure in an implant is required for identification and reparation of the damaged site. Magnetic Resonance Imaging (MRI) is an imaging modality that applies magnetic fields to non-invasively and safely image human anatomy. Metal implants distort the magnetic field, resulting in severe image artifacts. It is not possible to acquire diagnostic quality MRI images in the vicinity of metal implants with traditional methods. We propose to employ SPRITE MRI techniques, which are immune to the local magnetic field inhomogeneity, to acquire high quality distortion-free images. The method has been demonstrated in phantom measurements and compared to standard techniques. SPRITE MRI can be applied to other systems that are challenging for traditional MRI.
