title: 2D and 3D computed tomography of the pediatric hip.
abstract: The contribution of computed tomography with multiplanar reconstructions (2D CT) and animated three-dimensional reformatting (3D CT) has been well documented in the adult hip. The applications and utility in the pediatric hip prove to be similar. Coronal and sagittal 2D images are superior to transaxial CT in defining the superior pole of the femur, the superior joint space, and the acetabular roof and dome. 3D CT provides the best overview of morphology, integrating the 2D information for therapeutic planning. Studies can be modified or tailored for dose control, particularly in the youngest patients.
