局部复发性前列腺癌的经皮间质微波热消融术是在磁共振（MR）成像的持续指导下进行的。相位图像和数据获得了一个快速的梯度回波技术，并被用来推导组织的质子共振位移的基础上的温度变化。热失活区域与相位图像结果相关性良好。MR成像衍生的温度与荧光组织温度呈线性相关。MR成像可用于引导热消融。
Percutaneous interstitial microwave thermoablation of locally recurrent prostate carcinoma was continually guided with magnetic resonance (MR) imaging. Phase images and data were obtained with a rapid gradient-echo technique and were used to derive tissue temperature change on the basis of proton-resonance shift. Thermally devitalized regions correlated well with the phase image findings. MR imaging-derived temperatures were linearly related to the fluoroptic tissue temperatures. MR imaging can be used to guide thermoablation.
