Imaging in Legg-Calve-Perthes Disease

Imaging in Legg-Calve-Perthes Disease Alain Dimeglio and Federico Canavese Imaging in Legg-Calve-Perthes disease should help assess the severity and the stage of the disease, detect severe forms earlier, and provide guidance to therapy. However, due to the complexity of the disease, not all examinations can be performed at the same time with the same goals. The scope of this work is to provide an overview of all imaging techniques available today, and to help understand when to use a particular examination. Advantages and limitations of plain radiographs, bone scintigraphy, magnetic resonance imaging, arthrography, computed tomography, and ultrasonography are identified.
