Newly developed treatment for brain tumor under the MR temperature measurement

利用水质子化学位移技术进行磁共振测温是一种很有前途的体内温度监测方法。新的漫射投影®ber在MR温度测量的不同光学穿透中清晰可见。我们检测到在LITT过程中激光针尖周围的严重碳化问题，并在此描述了在LITT过程中使用MR温度监测调节温度的两种方法的组合，以减少这种碳化风险：扩散投影®ber和间歇照射方法的组合使用。磁共振测温不仅可以评估不同系统获得的温度误差，还可以确定治疗颅内病变的合适照射方法。

MR temperature measurement using the water proton chemical shift technique represents a promising method for temperature monitoring in vivo. The novel diffuse- projection ®ber is clearly visualized in different optical penetrations upon MR temperature measurement. We detected the serious problem of carbonization around the laser ®ber tip and during LITT, and herein described a combination of two methodologies that regulated tempera- ture during LITT using MR temperature monitoring to reduce this risk of carbonization: the combined use of a diffuse-projection ®ber and the intermittent irradiation method. Temperature measurement by MR not only evaluates the temperature pro®les obtained by different ®ber systems, but also determines the appropriate irradia- tion method for the treatment of intracranial lesions.
