The high soft tissue contrast of MR imaging enables superior tissue characterization of mediastinal masses, adding diagnostic specificity and often changing and benefiting clinical management. MR imaging can better discern…
Thymoma is the most common primary malignancy of the anterior mediastinum and the most common thymic epithelial neoplasm, but it is a rare tumor that constitutes less than 1% of…
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…
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…
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 (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…
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…
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…
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…
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…
