摘要
目的:分析比较小肠MR各序列的特点。方法:回顾我院2012年1月至2013年1月期间所做的116例小肠MR。所有病例均进行检查前肠道准备。所有病例的MR扫描均包含HASTE/T2SSFE,TureTISP/FIESTA、DWI、VIBE-T1/LAVA-T1及3D-T1增强扫描,18例行Functional Cine MRI检查。结果:HASTE/T2SSFE可清晰显示肠壁结构及肠壁增厚的程度;Ture-TISP/FIESTA清晰显示肠系膜结构;DWI有助于观察肠壁的炎症;3D-T1增强扫描可显示病灶的异常强化;VIBE-T1/LAVA-T1显示无异常强化的病灶;Functional Cine MRI则可以显示肠粘连及肠道的蠕动情况。结论:小肠MR检查各序列特性不同,互有所长,综合运用有助于小肠疾病的诊断。
Purpose： To compare the characteristics of intestinal MRI sequences. Methods： One hundred and sixteen cases of intestinal MRI examined in our hospital during Janurary 2011 to Janurary 2012 were analyzed retrospectively. Bowel preparation had been done in all cases before MRI examination. MR/sequences of all cases included HASTE/T2SSFE, Ture-TISP/FIESTA, DWI, VIBE-T1/LAVA-T1 and 3D-T1 enhanced scan. Functional Cine MRI had been added in 18 cases. Results： The structure and degree of thickening of the intestinal wall could be shown clearly in HASTE / T2SSFE. The structure of mesentery could be shown clearly in Ture-TISP/FIESTA. DWI sequences contribute to the observation of inflammation in intestinal wall. Abnormal enhancement of lesions could be shown in 3D-T1 enhanced scans. The lesions without abnormal enhancement could be shown in VIBE-T1/ LAVA-T1. Adhesions and intestinal peristalsis could be shown in fimctional Cine MRI. Conclusion： The strength of each intestine MRI sequence is different but complementary. Combined usage of them contribute to the diagnosis of small bowel diseases.
