摘要：
The present invention relates to medical instruments which can be guided into place using magnetic resonance imaging (MRI) or computed tomography (CT). The invention especially relates to penetrating instruments inserted percutaneously (e.g. needles), for use in a wide range of medical applications using MRI or CT, such as tumour localisation (e.g. in the breast), biopsy, drainage, tissue ablation, cannula, catheter or central line insertion, and in cosmetics. The instruments are provided with an anode and a cathode, such that, in use, current flows between the anode and cathode, thereby producing a plurality of bubbles.
