title: 3-D Isotropic MR Imaging for Planning Bone Reconstruction in Patients With Femoroacetabular Impingement.
abstract: BACKGROUND
  Femoroacetabular impingement (FAI) is commonly seen in young or middle-aged patients. Early detection and correction of FAI-related bony deformities or pelvic realignment are essential to prevent the development or progression of hip osteoarthritis.
  
  
  CONCLUSIONS
  Computed tomography (CT) and magnetic resonance (MR) imaging are the reference standards for the evaluation of bony anatomy and treatable internal derangement findings of the hip, respectively. Surgeons prefer CT imaging for preoperative bone delineation because of its 3-D isotropic capabilities and excellent multiplanar reconstructions. Three-Tesla (3T) MR scans enable high-resolution 3-D MR reconstructions for bone depiction similar to 3-D CT reconstructions and have the potential to eliminate the need for duplicate (CT and MR) scanning.
  
  
  CONCLUSIONS
  This technical report illustrates the feasibility of such an approach and compares bone rendering obtained using isotropic data from 3-D MR with 3-D CT in the same patient.
