Among MR plain scan sequences, T1W with fat suppression was outstanding in depicting the gross features of the tumor, presence of ulceration, and adjacent lymph node swelling.
在平扫序列中，T1W加脂肪抑制能较好地显示肿瘤特征、溃疡存在以及周围淋巴结肿大。
Conclusion: in 3d-flash sequences, water excitation technique as an alternative to fat suppression can shorten scan time significantly, without decreasing image quality.
结论：3d - FLASH序列合用水激发技术代替脂肪抑制可显著缩短扫描时间，而不降低图像质量。
