摘要
目的:探讨3.0 T MRI对肛瘘的术前诊断价值。方法:2018年1-12月收治肛瘘患者120例,采用3.0 T MRI超导成像仪进行诊断。比较分析MRI检查和手术病理检查结果。结果:MRI检查结果与手术病理检查结果一致性比较高。肛瘘线条状瘘管和支管T1WI信号为等信号或低信号,T2WI脂肪抑制序列信号为高信号,内口连接瘘管和直肠,肠壁局部中断、略厚,MRI信号特征表现为线条状的长T1长T2信号。肛周脓肿呈马蹄形、不规则形状,T1WI为低信号,T2WI为高信号,DWI为高信号,伴随则为略高信号。结论:3.0 T MRI超导成像仪信噪比高,分辨率高,采用MRI技术对肛瘘进行术前诊断,可以准确确定瘘管位置和走向,为准确判断瘘管和周围组织关系和找到内口位置提供可靠信息。
Objective:To explore the value of 3.0 T MRI in the preoperative diagnosis of archosyrinx.Methods:From January to December 2018,120 patients with archosyrinx were enrolled,and they were all diagnosed with a 3.0 T MRI superconducting imager.The results of MRI and surgical diagnosis were compared.Results:The results of MRI were more consistent with the results of surgical pathology.The T1WI signal of anal fistula linear fistula and branch was equal signal or low signal;the signal of T2WI fat suppression sequence was high signal;the internal orifice connects the fistula to the rectum,;the intestinal wall was locally interrupted and slightly thicker;MRI signals was characterized by linear long T1 and long T2 signals.Perianal abscess was horseshoe and irregular in shape,T1WI was a low signal;T2WI was a high signal and the DWI was a high signal,which with fester was slightly higher signal.Conclusion:3.0T MRI superconducting imager has high noise-signal ratio and high resolution.The preoperative diagnosis of archosyrinx by MRI technique can accurately determine the location and direction of archosyrinx and provide reliable information for accurately judging the relationship between fistula and surrounding tissue and finding the position of internal orifice.
