Recently, an add-on solution for real-time navigation of percutaneous procedures outside the bore has been presented and clinically deployed. The purpose of this work was to thoroughly evaluate the diagnostic accuracy and workflow of 240 experimental biopsies by different operators. The mean success rate (93%) and median biopsy time (3:58 min, including MR table movements and control scan) observed for attending radiologists suggest that an "in-and-out" approach does not necessarily compromise diagnostic accuracy or clinical workflow. While the clinical performance can only be assessed on patients, this work provides valuable results for a large number of biopsies and different operators.
