磁共振成像方法
摘要：
本发明提供的磁共振成像方法，包括采用反转恢复序列激发被扫描对象，获得反转恢复图像：对反转恢复图像进行处理，获得对应的实部图像：获得与所述实部图像对应的、不带反转恢复的参考图像信号线：对所述参考图像信号线进行相位校正，得到相位校正后的参考图像信号线：根据相位校正后的参考图像信号线，确定所述实部图像的极性。本技术方案解决了反转恢复序实部成像中，实部图像不同组织信号极性判断不准确的问题，通过额外采集参考图像信号线，计算所述参考图像信号线实部和值的正负，来判断实部图像极性，无需对图像本身或扫描参数作相关假设，能够稳定正确地确定所有部位实部图像的极性。
摘要（英）：

The method for magnetic resonance imaging described in the present disclosure may include generating an inversion recovery image by scanning an object using an inversion recovery sequence. The method may also include generating a real part image corresponding to the inversion recovery image by processing the inversion recovery image. The method may also include obtaining a signal line of a reference image without inversion recovery, the reference image corresponding to the real part image. The method may also include determining a phase-corrected signal line of the reference image by performing a phase correction on the signal line of the reference image. The method may also include determining a polarity of the real part image based on the phase-corrected signal line of the reference image.
