title: Osteoarthritis year 2012 in review: imaging.
abstract: OBJECTIVE
  This article reviews original publications related to imaging in osteoarthritis (OA) published in English from September 2011 through March 2012. In vitro data and animal studies are not covered.
  
  
  METHODS
  To extract relevant studies, an extensive PubMed database search was performed using the query terms "osteoarthritis" in combination with "MRI", "imaging", "radiography", "ultrasound", "computed tomography" and "nuclear medicine". Publications were sorted according to relevance based on potential impact to the OA research community with the over all goal of a balanced overview of all aspects of imaging. Focus was on publications in high-impact special-interest journals. The literature will be presented by topics covering radiography, morphologic magnetic resonance imaging (MRI), compositional and high-field MRI, quantitative MRI, ultrasound, other joints and systematic reviews. Original research that was presented as a podium or poster presentation at osteoarthritis research society international (OARSI) 2012 will not be included.
  
  
  CONCLUSIONS
  For the search topics "MRI" and "osteoarthritis" a decrease in overall publications was observed over the 6 months following September 2011 when compared to the previous 6 months (-38.1%). For the terms "radiography" and "osteoarthritis" a decrease of 56.9% was noted. The 6 months since the last OARSI conference were characterized by several MRI-based studies dealing with epidemiologic and methodologic aspects of disease. Other modalities such as radiography or ultrasound received much less attention. Most imaging research is still concentrated on the knee although interest in other sites, especially the hand, has increased since the last OARSI meeting.
