[Minimally invasive surgery with MRI imaging].

The main shortcoming of conventional laparoscopic procedures is the lack of a truely three-dimensional view. The development of a open-configured MR-imaging system (0.5 Tesla, General Electric, USA) with free access to the patient, allows the performance of minimal invasive procedures under MR-guidance. Advantages inherent to minimal invasive surgery can now be combined with the ideal tissue discrimination and the temperature sensitivity of MR-imaging. This new method can be used for diagnostic as well as for therapeutic interventions, especially interstitial therapy of inoperable metastases of parenchymal organs.
