[Safety aspects in interventional MRI].
Because of its high soft-tissue contrast, Magnetic Resonance Imaging (MRI) is used increasingly for guidance and control of minimal invasive and neurological surgical procedures. Besides common precautions during an MRI investigation, special attention has to be paid to the consequences of MR compatibility, accuracy of localisation of interventional tools and geometrical distortions. As a new application of interventional MR intravascular procedures are developing that involve the introduction of guidewires, catheters and miniaturized coils with their leads into the blood vessels. Resonant currents and high electric fields can develop at the conductor ends, possibly causing burning lesions.
