【摘要】 目的:探讨MRI检查应用于肛瘘诊断中的临床价值。方法:选取我院2009年12月～2012年12月间确诊为肛瘘的患者28例,在术前进行MRI检查,分析MRI上肛瘘的表现,将影像学检查的结果与手术结果进行对照。结果:28例肛瘘手术显示存在49个瘘管,32个内口,5个脓肿;与手术结果相比:MRI检出存在瘘管47个,符合率为95.9%;准确显示瘘管内口位置24个,符合率为75%;脓腔的检出率为100%。结论:采用MRI能够准确显示出肛瘘的内口、瘘管位置,以及脓肿的有无、位置,临床符合率高。是一种重要的有价值的肛瘘诊断方法。更多还原

【Abstract】 Objective:To investigate the clinical value of applying MRI to diagnosis of anal fistula.Methods:Twenty-eight patients with anal fistula were undergone preoperative MRI examination between December 2009 and 2012 in our hospital.The MRI presentations were retrospectively analyzed and compared with the operative findings.Results:The operation revealed 49 fistulae,32 internal openings and abscess in 5 sites in the total 28 cases required closure of anal fistula.Compared with the operative findings,MRI represented 47 fistulae(95.9%) and 24 internal openings(75%) as well as 5 sites of abscess(100%).Conclusion:MRI can be effective to detection of anal fistula,for it is capable of accurately identifying the internal opening and location for the fistula as well as both sites of the abscess if present.更多还原
