Magnetic resonance imaging in the diagnosis of anterior tibialis muscle herniation.

Magnetic resonance imaging (MRI) can be employed to successfully image the fascial compartments of the leg. Herniated muscle tissue and fascial discontinuity can each be unequivocally identified. Both the extent of fascial splitting and the size of the muscle herniation can be demarcated and quantified. MRI is favored over computed tomography because of its superior ability to distinguish soft-tissues structures, making it possible to see both muscle and fascia separately.
