title: [Magnetic resonance tomography and interventional measures].
abstract: In contrast to conventional radiography or ultrasonography, magnetic resonance imaging (MRI) is influenced by different factors. As a consequence, tissues and fluids can be visualized using different techniques. Obviously MR imaging has a lot of advantages, but only a small number of disadvantages and contraindications. Without using X-rays, interventions can be done under real-time MR control. An open-configuration MR-system allows vertical access to the patient during interventions. The combination of laparoscopy and MR imaging enables the surgeon to observe organ surfaces as well as parenchymal structures at the same time. Depending on the high temperature sensitivity of MR imaging, this technique can be used to guide interstitial laser therapy or cryosurgical interventions.
