提出了一种回波平面光谱温度成像方法。该方法比所谓的3D磁共振光谱成像（3D-MRSI）方法足够快，并且不需要图像减法，这与当内部参考信号可检测时的常规相位映射方法不同。通过使用组织脂质作为内部参考物测量的水质子化学位移清楚地可视化了体外猪肝样品中的温度变化。它还表明，内部参考回波平面光谱成像方法可以显着减少扫描之间的一个简单的，平移运动所造成的温度误差相比，相位映射方法。(C)2000 Wiley-Liss，Inc.
An echo-planar spectroscopic imaging method of temperature mapping is proposed. This method is sufficiently faster than the so-called 3D magnetic resonance spectroscopic imaging (3D-MRSI) method and does not require image subtractions, unlike the conventional phase mapping method when an internal reference signal is detectable. The water proton chemical shift measured by using the tissue lipid as an internal reference clearly visualized the temperature change in a porcine liver sample in vitro. It was also demonstrated that the internally referenced echo-planar spectroscopic imaging method could markedly reduce a temperature error caused by a simple, translational motion between scans compared with the phase-mapping method.
