title: Emerging specialty areas in MR imaging: an initial study.
abstract: OBJECTIVE
  The purpose of this study was to analyze magnetic resonance (MR) technologist practice data to determine if MR specialty areas exist.
  
  
  METHODS
  The American Registry of Radiologic Technologists distributed an MR practice analysis questionnaire to a random sample of 1000 registered MR technologists. Task statements were assessed to determine the type and frequency of procedures performed by MR technologists.
  
  
  RESULTS
  Of the 121 task statements collected, the author analyzed 78 tasks and found 4 meaningful factors accounting for 47.86% of the total variance. In addition, 3 specialty areas emerged in separate reviews of the tasks listed in each of the 4 factors.
  
  
  CONCLUSIONS
  Using factor analysis to assess the data, vascular/cardiovascular imaging, central nervous system imaging and musculoskeletal imaging were identified as specialty areas.
