Study has largely focused on orthopaedic applications of magnetic resonance imaging (MRI), including the validation of pulse sequence parameters suitable for detecting meniscal repair, labral tears (hip and shoulder), and articular cartilage. We have validated a pulse sequence suitable for non-invasively detecting traumatic cartilage injury, as well as provided an objective outcome assessment of cartilage repair techniques. More recent research has focused on the use of quantitative T2 mapping to detect alterations in the collagen orientation of the extracellular matrix, which precedes loss of cartilage thickness. Validation has been performed in a nonclinical osteoarthritis model, with additional correlative collaboration with Nancy Camacho, PhD, using Fourier transform infrared spectroscopy. In addition, Dr. Potter has worked on alteration of pulse sequence parameters and MR sequences to decrease the susceptibility artifact generated by orthopaedic instrumentation, most recently to more accurately locate and quantify the degree of osteolysis complicating joint arthroplasty, as well as assess intracapsular synovial deposits prior to osteoclastic resorption of bone.
