Recently, microwave coagulation therapy (MCT) for liver tumor is expected as minimally invasive therapy. On the other hand, developing of open MR scanner, MR fluoroscopy technique and MR compatible instruments allows performing interventional MRI. The thermal imaging potential of MR was considered with regard to its temperature sensitivity. We tried MR guided and monitoring PMCT ex vivo using these techniques to safely and accurately perform this PMCT before clinical application. We evaluated artifact of microwave instruments and feasibility of MR temperature monitoring during PMCT. Causes of image artifact were known. MR temperature images correspond with temperature change. In future, MR guidance and temperature monitoring of PMCT appears feasible, clinically.
