Imaging of the postoperative spine.

Spinal instrumentation techniques have expanded dramatically during the past several decades, but the search for the perfect operative approach and fixation system continues. Fixation devices are designed for the cervical, thoracic, lumbar, and sacral segments using anterior, posterior, transverse, videoarthroscopic, and combined approaches. In most cases, bone grafting also is performed, because instrument failure occurs if solid bony fusion is not achieved. Radiologists must understand the operative and instrumentation options. Knowledge of expected results, appearance of graft material, and different forms of instrumentation is critical for evaluating position of implants and potential complications associated with operative approaches and spinal fixation devices.

Imaging of joint replacement procedures.

Joint replacement procedures have improved dramatically during the past 30 years fueled by the changes in techniques for hips and knees. Joint replacements in other anatomic regions also have become more popular. It is essential to understand the importance of pre- and postoperative imaging for evaluating patients. Preoperative images are used in concert with clinical data to select the appropriate patients and components. Postoperative imaging is critical for evaluating position and potential complications. Appropriate selection of imaging modalities is essential to provide optimal, cost-effective patient care.

Postgraduate musculoskeletal fellowship training in the United States: current trends and future direction.

OBJECTIVE: To document current postgraduate musculoskeletal training program (accredited and unaccredited) curricula and approaches to education. DESIGN AND PATIENTS: Questionnaires were sent to all musculoskeletal training programs. Responses regarding radiology residency and fellowship program sizes, types of imaging and invasive procedures included, and other program parameters were solicited. Features of accredited and unaccredited programs were compared. Teaching approaches, including the use of web-based or distance learning were evaluated. RESULTS: Twenty-nine (73%) of 40 musculoskeletal programs responded to the questionnaire. Twenty-eight percent of programs were accredited and 72% unaccredited. Radiology residencies were also present at all responding institutions (the majority had a class size of 4-8/year). Residency programs in related specialties included pathology 96%, orthopedics and rheumatology 90%, oncology 83% and pain management 69%. The majority (93-100%) provided training in radiography, MRI and CT. Spine MRI was included in 69% of programs, ultrasonography in 62% and positron emission tomography in 24%. Arthrography and diagnostic and therapeutic injections (100%) were included in all programs. Other invasive procedures, including spine and radiofrequency ablation, were offered less frequently. Teaching approaches included conferences (100%), journal clubs (62%), multidisciplinary conferences (45-90%), web-based learning (30%) and distance learning (7%). Forty-one percent of programs offered off-site rotations. CONCLUSIONS: The majority of musculoskeletal training programs prepared trainees for private or academic practice. There are inconsistencies that could be improved to better prepare trainees for careers in musculoskeletal imaging.

Evaluation of collateral ligament injuries of the metacarpophalangeal joints with magnetic resonance imaging and magnetic resonance arthrography.

Injuries of the collateral ligaments of the metacarpophalangeal (MCP) joints of the hand require accurate diagnosis and prompt treatment to prevent loss of function. The most common and well-known collateral ligament injury is injury to the ulnar collateral ligament of the first MCP joint of the hand, often referred to as a gamekeeper injury. Although less common, injuries involving the collateral ligaments of the second through fifth digits and the radial collateral ligament of the first digit also occur. The diagnosis of collateral ligament injury is often made clinically, however, magnetic resonance imaging and magnetic resonance arthrography of the MCP joints can be very useful in the evaluation of severity of the injury. This provides important information for the hand surgeon and aids in treatment planning. Imaging of the collateral ligaments requires small fields of view and several technical considerations can provide improved image quality. These factors will be discussed and illustrated in this article.
