We started microwave ablation therapy of liver tumors under MR image guidance with an open configuration MR scanner. The combination of these two was quite feasible. At the beginning, preparations of MR compatible electrodes and a noise-eliminating filter were required. After the measurements against the noise, microwave irradiation did not disturb MR images and temperature changes could be monitored using MR temperature maps, which were useful for the real-time evaluation of therapeutic effects. In addition, MR temperature maps could be used to investigate the condition of microwave ablation with newly developed instruments and applications. The encounter of microwave ablation with MR imaging made a breakthrough in the image-guided minimally invasive therapy. Further developments of new technologies for therapeutic procedures are expected from this combination.

Microwave Ablation is one of the useful treatments of hepatic tumor. It has been used as an interventional device for thermoablation therapy under ultrasonographic or laparoscopic guidance. We have done clinical studies of MR-guided microwave ablation therapy of hepatic tumors since January 2000. From January through September 2000, 18 patients with liver tumors were hospitalized in the 1st Department of Surgery at Shiga University of Medical Science. There were 13 cases of metastatic hepatic tumor. All of which had previously had primary surgery. The other 5 cases were primary hepatic cancer. All patients were selected because percutaneous ethanol injection therapy (PEIT) or transcathetal arterial embolization (TAE) was ineffective, and surgical resection could not be done because of hepatic dysfunction.We had already performed MR-guided microwave ablation therapy to hepatic tumors located in every segment of the liver. However, percutaneous puncture of the tumors in the subphrenic area was not easy with the abdominal approach. In these cases, a combination of thoracoscopic and MR-guidance has been beneficial. MR compatible endoscope made us easily to puncture hepatic tumors located in every segment of the liver. MR-guided microwave ablation therapy is a feasible treatment for hepatic tumors.
