| Research Abstract |
Image guided ablation therapy of liver cancers based on simultaneous use of open MRI and ultrasound (US) was proposed to improve safety and accuracy of the treatment. Phantom and animal experiments revealed errors were only 2-3mm using both MRI and US. The ablation therapy was performed for 51 liver tumors in 34 patients and punctures into tumors were successful in all cases. No mortality or major complications were occurred. The present system using both MRI and US allows a safe and accurate approach to liver cancers.
