The Musculoskeletal (MSK) Radiology staff consists of full-time specialists, Drs. Cheung and Goodwin, and the support of a part-time staff consisting of neuroradiologist and spine-imaging specialist Dr. McIntyre, and Dr. Seltzer of the nuclear imaging division. The division provides image interpretation, consultation, and interventional services for patients with disease or injury of the axial and appendicular musculoskeletal system, especially of the bones and joints. Modalities include X-ray, MRI, fluoroscopy, ultrasound, CT, and DXA. Interventional procedures are a growing component of our practice, and include arthrography services, epidural steroid injections, and image-guided biopsies of bone and soft tissue. Bone densitometry (DXA) is performed by a staff of certified technologists, and interpreted by Drs. Cheung, Goodwin, and Seltzer. Volumes have increased strongly in all areas of our service, driven in part by the growth in orthopedics and rheumatology referrals, particularly for hand surgery and myositis imaging requests. We utilize almost all imaging modalities of the department, but would highlight several new MR acquisitions: the ONI Systems 1.5T "MSK Extreme"—a magnet which combines the simplicity of patient comfort of small extremity imaging with the power of a full-sized system; and the GE Discovery™ 3T system installed in March of this year.
The MSK staff is active in imaging research. Dr. Cheung, who anticipates completing the MS program at TDI this year, recently completed (with former chief resident, Dr. Kiley Perrich) a comprehensive series of ankle-ligament studies which was published in the AJR last year. Dr. Goodwin has collaborated with Dr. Kauppinen of our NMR Research Center on studies of the structure and imaging properties of articular cartilage; current work includes a project correlating cartilage T2 with immunohistochemistry of early degenerative changes in articular cartilage in the human knee.
