title: [Coxarthrosis - a radiological approach and guidelines].
abstract: OBJECTIVE
  Coxarthrosis is one of the most frequent indications in radiological practice with a prevalence as high as 8%.
  
  
  METHODS
  Radiography, sonography, computed tomography, magnetic resonance imaging.
  
  
  METHODS
  Magnetic resonance arthrography for detection of early stages of labral and chondral pathologies as well as detection of osteonecrosis at an early stage.
