MAGNETIC RESONANCE VISIBLE MARKERS FOR MAGNETIC RESONANCE IMAGING GUIDED BRACHYTHERAPY

摘要

Magnetic resonance ("MR") visible markers for use in MR-guided placement of brachytherapy seeds, and for use in other MR-guided interventional procedures, are described. The MR-visible markers generally include a tube in which an absorbent thread assembly is disposed. The tube is made fluid-tight by sealing it at both ends with suitable end plugs. The absorbent thread assembly is soaked in a suitable MR-visible fluid.
