三点狄克逊（3PD）MR成像的一种新的相位校正算法允许对每个切片的三个图像进行在线图像重建：纯水、纯脂肪和水加脂肪。当与快速自旋回波采集相结合时，该序列适用于球后间隙的常规MR成像。3PD纯水图像的图像信噪比是快速自旋回波反转恢复图像的两倍。3PD纯脂肪图像的显著对比噪声比可以提供改进的病变检测。
A new phase-correction algorithm for three-point Dixon (3PD) MR imaging allows on-line image reconstruction of three images per section: pure water, pure fat, and water plus fat. When combined with fast spin-echo acquisition, the sequence is suitable for routine MR imaging of the retrobulbar space. The 3PD pure water images have double the image signal-to-noise ratio of fast spin-echo inversion recovery images. The dramatic contrast-to-noise ratio of the 3PD pure fat images may offer improved lesion detection.
