Magnetic resonance imaging in adolescent symptomatic navicular tuberosity.

Background: The accessory navicular bone is one of the most common accessory ossicles, which sometimes become symptomatic. Abnormalities in magnetic resonance (MR) image, e. g.

Significance of magnetic resonance imaging signal change in the pedicle in the management of pediatric lumbar spondylolysis.

Study Design: Prospective study.

Objective: To investigate the time course of signal changes in the adjacent pedicle in fresh pediatric lumbar spondylolysis.

Summary Of Background Data: A recent study reported that high signal change (HSC) on T2-magnetic resonance image (MRI) in the pedicle adjacent to the pars interarticularis could be an indicator of early spondylolysis.
