Abstract

To obtain objective and concrete data by physically assessing the quality of breast magnetic resonance images based on the fat-suppression effect by the modified Dixon method (mDixon) and frequency-selective fat suppression (e-Thrive) using an original lipid-content breast phantom that could easily reveal the influence of non-uniform fat suppression in breast magnetic resonance imaging. The fat-suppression uniformity was approximately seven times superior when using mDixon compared with when using e-Thrive. mDixon appears to have a significant advantage.

摘要

通过使用原始脂质含量乳腺体模对基于改良 Dixon 法（m Dixon）和频率选择脂肪抑制（e-Thrive）的脂肪抑制效果进行物理评估，获得客观具体的乳腺磁共振图像质量数据，该体模可轻易显示乳腺磁共振成像中不均匀脂肪抑制的影响。与 e-Thrive 相比，m Dixon 时的脂肪抑制均匀性大约高出七倍。m Dixon 似乎具有明显优势。
