Guidewire, guiding catheter and MR-bioptome visualized by real-time CMR pre biopsy. The instruments with MR-markers are visualized by interactive real-time CMR during a targeted biopsy. a: The guidewire (blue arrow with square end) and the guiding catheter (yellow arrow with square end) are advanced into the left ventricle through the aorta. b: The MR-conditional bioptome is used to perform a biopsy (violet arrow with round end) c and d: The bioptome (violet arrow with round end) is advanced inside (c) and then extruded out of (d) the guiding catheter (yellow arrow with square end)
