title: MR-guided bone biopsy: preliminary report of a new guiding method.
abstract: OBJECTIVE
  To evaluate the feasibility of a new MR compatible optical tracking guided bone biopsy system.
  
  
  METHODS
  Wireless optical tracker elements were connected to a bone biopsy set. Biopsies of five different anatomic areas and lesions varying from 9 mm to 40 mm (mean 25 mm) in size, were performed.
  
  
  RESULTS
  We were able to perform the biopsies in all cases, and the samples allowed for a pathologic diagnosis. The procedure time was limited to less than 40 minutes, and no complications occurred.
  
  
  CONCLUSIONS
  MR-guided bone biopsy with this new guiding system was a feasible and fast procedure that did not compromise the usability of the bone biopsy set.
