Abstract

The management of premature physeal arrest requires accurate assessment of not only the location but also the extent of the bar. Numerous imaging techniques are available to evaluate the physis. Multiplanar tomography has proven to be the most precise method. The utility of magnetic resonance imaging (MRI) of physeal bars has not been demonstrated. This article presents MRI results in two cases of physeal bars. MRI provides a means of assessing physeal bar formation with an accuracy approaching that of multiplanar tomography. In certain instances, its efficacy may exceed that of tomography, specifically when the physis cannot be properly oriented for tomographic evaluation, when more planes are desired, and when radiation exposure is thought to be excessive. With improvement of its capabilities and availability (which may also reduce cost), it may become the diagnostic imaging technique of choice.
