Computed tomography (CT) scanograms provide an accurate method for evaluation of leg-length discrepancy. Flexion of a leg may be missed on a single frontal projection, and the measurements obtained will be erroneously shortened. When performing CT sonography, lateral views of the limbs may be easily and rapidly obtained without having to change the position of the patient. This permits assessment of limb flexion.
