Sports-related muscle injuries of the lower extremity: MR imaging appearances.

Sports-related injuries of the lower extremity are frequent. Before magnetic resonance (MR) imaging was available, ultrasound, radionuclide scintigraphy and computed tomography were used to evaluate muscle trauma. Although relatively inexpensive, these imaging modalities are limited by their low specificity. The high degree of soft tissue contrast and multiplanar capability of MR imaging, allow direct visualization as well as characterization of traumatic muscle lesions. This pictorial review highlights the spectrum of traumatic muscle lesions on MRI, with emphasis on its typical appearances.

Posterior tibial tendon dysfunction as a cause of acquired flatfoot in the adult: value of magnetic resonance imaging.

Dysfunction of the posterior tibial tendon is the most common cause of acquired flatfoot in adults; despite this, the condition is not commonly recognized. We report three cases with flatfoot secondary to spontaneous tendon rupture, in whom magnetic resonance imaging (MRI) was a helpful non-invasive technique to confirm the suspected diagnosis. This disabling entity, and the usefulness of MRI in the diagnosis and planning the appropriate treatment, are reviewed.
