目的分析T2 WI和扩散加权成像(DWI)相结合在评价直肠癌系膜浸润的应用价值.方法回顾性分析16例术前常规MRI检查T2 WI显示直肠旁与直肠分界不清的条索影从而导致术前准确分期困难的直肠癌患者,将DWI表现与手术病理结果对照分析.结果16例T2 WI显示的等信号直肠旁条索影,DWI显示为等信号的7例,为高信号的9例,术后病理证实直肠旁无系膜浸润的7例DWI均表现为等信号;存在直肠旁系膜浸润的9例DWI均显示为高信号.结论 DWI和T2 WI相结合是评价直肠癌系膜浸润的一种非常有效的方法.

@@@@Objective To evaluate the application of T2 WI combined with DWI in mesorectal fat invasion of rectal carcinoma. Methods Data of 16 patients with rectal carcinoma proved by postoperative pathology were reviewed retrospectively. All patients underwent MRI scanning before surgery and were found trabs abnormal signal intese on T2 WI in mesorectal fat which were ill-defined with rectal. Results Trabs abnormal signal intense on T2 WI in the mesorectal fat and ill-defined with rectal can be seen in 16 cases. Isointense on DWI can be found in 7 cases which were proved to be no mesorectal fat invasion by postoperative pathology, and hyperintense on DWI in 9 cases proved to be mesorectal fat invasion. Conclusion It is an effective and useful method to evalue mesorectal fat invasion of rectal carcinoma that T2 WI combined with DWI.
