Internal Impingement Syndromes
Internal causes of impingement are secondary to rotator cuff and capsular dysfunction and are categorized by the location of the impingement and the underlying pathophysiological or mechanical cause of the…
Magnetic Resonance Imaging of Rotator Cuff Disease and External Impingement
Magnetic resonance (MR) imaging plays a major role in helping to identify rotator cuff disease and in demonstrating the pathology associated with external impingement. Many surgeons rely on MR imaging…
Novel Anatomic Concepts in Magnetic Resonance Imaging of the Rotator Cuff Tendons and the Footprint
The anatomic and histologic descriptions of the rotator cuff tendons and footprints are continuously evolving, and new discoveries have led to novel concepts in our understanding of rotator cuff tendon…
Technical Update on Magnetic Resonance Imaging of the Shoulder
Improvement in both hardware and software has opened up new opportunities in magnetic resonance (MR) imaging of the shoulder. MR imaging at 3-T has become a reality, with the prospect…
Patterns of Perineural Tumor Spread in Head and Neck Cancer
Perineural tumor spread (PNS) is a mode of neoplastic spread whereby tumor cells use neural conduits to escape the borders of a primary tumor. MRI is generally favored over CT…
Magnetic Resonance Imaging of the Pediatric Neck
Evaluation of neck lesions in the pediatric population can be a diagnostic challenge, for which magnetic resonance (MR) imaging is extremely valuable. This article provides an overview of the value…
