The aim was to establish a training model for MRI-PTCD and to compare procedure times of MRI and conventional radiologic guided PTCD. An in-vitro model was used in an open-MRI-scanner 1.0 Tesla. The success rates, puncture time by MR-guidance and by conventional methods using the same model, and learning curve were calculated. The successful puncture rate in the oMRI group was significantly higher, puncture time shorter. The learning curve of MRI-PTCD showed a shorting in puncture time for the last 15 punctures. Initial in-vitro experience shows that PTCD can be successfully and rapidly performed under real-time-MRI-guidance and can also be used for training.
