MRI-Guided Brachytherapy in the Liver
Percutaneous brachytherapy, an ablative therapy achieving substantial tumor kill by directly applying ionizing radiation to solid tumors in the liver, is introduced. An interventional magnetic resonance environment, using a modified 1.0 T open MRI system and commercially available as well as custom-made components, is presented. The interventional procedure, from premedication to the MRI-guided therapeutic process to final process control is explained in detail. Subsequent irradiation therapy, follow-up, and tumor control are illustrated.
