CT and MRI of hip arthroplasty

Plain films are the initial imaging method of choice for evaluation of hip arthroplasty. Recent advances in technology and imaging techniques have largely overcome the problems of beam hardening in computed tomography (CT) and magnetic susceptibility artefact in magnetic resonance imaging (MRI). CT and MRI have now become useful imaging techniques in the assessment of hip arthroplasty. (c) 2007 The Royal College of Radiologists. Published by Elsevier Ltd. All rights reserved.
