Epiphyseal growth plate: evaluation with modified coronal CT.


:A method of modified coronal computed tomography (CT) was developed for examination of epiphyseal growth plate arrest and neoplasms near the growth plate. Twenty-four patients were examined with this technique (26 examinations). In all cases, the growth plate and adjacent regions were well demonstrated.
