Abstract

The technique of interventional on-line MR-guided procedures in a 0.2 Tesla open magnet is presented. 72 procedures were performed including 60 brain biopsies and 12 interventions as catheter placement for cyst or abscess drainage. The advantages and limitations are discussed and recent developments such as MR-coil designs and MR-sequences are presented.
