Key MR Imaging Features of Common Hand Surgery Conditions
The introduction of 3-T MR imaging scanners as well as dedicated wrist coils has allowed for scanning of the unique anatomic structures within the hand with unprecedented accuracy. In this…
Magnetic Resonance Angiography of the Upper Extremity
The magnetic resonance angiography (MRA) toolbox includes a wide array of versatile methods for diagnosis and therapy planning in patients with a variety of upper extremity vascular pathologies. MRA can…
MR Imaging of the Nerves of the Upper Extremity
The peripheral nervous system is susceptible to a diverse array of pathologic insults, broadly categorizable into those entities intrinsic to the nerves themselves, either primarily arising within the nerve(s) or…
Magnetic Resonance Arthrography of the Wrist and Elbow
Magnetic resonance (MR) arthrography of the wrist and elbow is useful for detecting a variety of intra-articular pathologies. MR dictations should address whether intrinsic ligament tears of the wrist are…
MR Imaging of Soft-Tissue Tumors of the Upper Extremity
Certain soft-tissue tumors seem to be specific to the upper extremity; most are benign. Knowledge of key magnetic resonance features, with clinical history and epidemiologic knowledge, can assist the radiologist…
MR Imaging of the Elbow
Almost all movements of the upper extremities during routine daily life and many athletic activities require a painless and stable elbow joint. Studying the elbow is a diagnostic challenge because…
Imaging of the Proximal and Distal Radioulnar Joints
The proximal and distal radioulnar joints form a unique articular arrangement between the radius and ulna, allowing pivot motion of the forearm and positioning the hand in space. Typically imaged…
MR Imaging of Carpal Fractures
Timely diagnosis of carpal fractures is important for optimal treatment outcome. Magnetic resonance (MR) imaging performed early in the workup can provide an accurate and specific diagnosis, as well as…
MR Imaging of Wrist Ligaments
This article discusses the normal anatomy and pathologic appearances of the intrinsic and extrinsic wrist ligaments using MR Imaging. Technological advances in surface coil design and higher magnetic field strengths…
MR Imaging of the Triangular Fibrocartilage Complex
MR imaging has emerged as the mainstay in imaging internal derangement of the soft tissues of the musculoskeletal system largely because of superior contrast resolution. The complex geometry and diminutive…
