A combination of frequency selective excitation and saturation is used to separated water and fat components in magnetic resonance imaging. In conjunction with a gradient echo sequence (fast low angle) shot and a three-dimensional data acquisition, a large volume of the body can be covered. A set of 32 water or fat images can be obtained within 3.5 min using a repetition time of 50 ms and a 256 x 256 half Fourier space matrix. As no correction data or additional image calculations are necessary, the method can easily be applied to routine examinations.
在磁共振成像中，频率选择性激发和饱和相结合用于分离水和脂肪成分。结合梯度回波序列（快速低角度）扫描和三维数据采集，可以覆盖身体的大部分区域。使用50毫秒的重复时间和256×256半傅里叶空间矩阵，在3.5分钟内可获得一组32幅水或脂肪图像。由于无需校正数据或额外的图像计算，该方法可轻松应用于常规检查。
