title: Percutaneous MR-guided radiofrequency ablation of recurrent sacrococcygeal chordomas.
abstract: OBJECTIVE
  Radiofrequency ablation is emerging as a therapeutic technique for the treatment of an increasing variety of tumors. Exact visual guidance to the tumor and controlled delivery of energy is pivotal for ablation success.
  
  
  CONCLUSIONS
  Introducing MRI as a guidance technique ideally uses tumor-specific tissue characteristics, allows direct multiplanar reconstruction for precise needle positioning, and permits real-time monitoring and assessment of treatment-induced tissue signal changes to increase the safety of the procedure.
