Abstract
Purpose To evaluate the feasibility of a new MR compatible optical tracking guided bone biopsy system. Materials and 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. Conclusion 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. J. Magn. Reson. Imaging 2002;15:82–86.
