Overview

abstract

  • PURPOSE: The availability of open whole body MRI magnets and MR-compatible instrumentarium were essential conditions for the progression of interventional MRI. The advantages of an MR-guided biopsy at the musculoskeletal system are the visualization of the puncture site of a representative area for tumor histology, the absence of exposure to radiation and the free selection of imaging planes. The purpose of the study was the development of a new technique of a secure MR-guided biopsy of intraosseus lesions in the humeral head. MATERIAL AND METHODS: MR-guided core biopsy of a intraosseus lesion of the humeral head was performed in five male patients on a vertical open, whole body MRI magnet (SIGNA SP/i 0.5T, GE Medical Systems). The technique using interactive MRI and the MR-compatible instrumentarium are described. RESULTS: A secure core biopsy could be obtained from a representative area for tumor histology in all cases. No complications occurred, especially no nerve or vessel lesion, no rotator cuff lesion and no intra-articular contamination of the shoulder joint were observed. CONCLUSION: A new technique is presented to obtain MR-guided core biopsies of intraosseous lesions of the humeral head. Furthermore, clinical indications of this technique are described.
