Objective: To assess the feasibility of MR (magnetic resonance)-guided bone
biopsies. Design and patients: Thirty-six consecutive patients with known
or suspected benign or malignant bone lesions underwent comprehensive MR im
aging. A dynamic contrast-enhanced sequence followed by stationary T1-weigh
ted sequences were obtained and MR-guided bone biopsy of the tumor at the s
ite with fastest enhancement was performed using an open 0.23 T MR imager.
Results: All MR-guided bone biopsies samples were estimated to be sufficien
t by the pathologists. The biopsy specimens were diagnostic in 34 of 36 cas
es. Conclusion: MR-guided bone biopsies combined with dynamic contrast-enha
nced imaging are feasible and safe for the diagnostic investigation of equi
vocal bone lesions.
