Dynamic contrast-enhanced MR imaging and MR-guided bone biopsy on a 0.23 T open imager.
OBJECTIVE
To assess the feasibility of MR (magnetic resonance)-guided bone biopsies.


METHODS
Thirty-six consecutive patients with known or suspected benign or malignant bone lesions underwent comprehensive MR imaging. A dynamic contrast-enhanced sequence followed by stationary T1-weighted sequences were obtained and MR-guided bone biopsy of the tumor at the site with fastest enhancement was performed using an open 0.23 T MR imager.


RESULTS
All MR-guided bone biopsies samples were estimated to be sufficient by the pathologists. The biopsy specimens were diagnostic in 34 of 36 cases.


CONCLUSIONS
MR-guided bone biopsies combined with dynamic contrast-enhanced imaging are feasible and safe for the diagnostic investigation of equivocal bone lesions.
