多排螺旋CT与磁共振成像影像学下复杂性肛瘘图像对比研究

Comparative study of complex anal fistula images under multi-slice spiral CT and MRI imaging

目的:对比研究多排螺旋CT(MSCT)与磁共振成像(MRI)影像学下复杂性肛瘘图像的优劣,为临床诊断提供依据。方法:回顾性分析24例确诊为复杂性肛瘘并进行手术治疗的患者MSCT及MRI检查资料,分别观察、对比分析复杂性肛瘘患者CT及MRI的成像特点。结果:MSCT对肛瘘的位置、走形、数目以及分支等与手术结果一致,诊断准确率达到100%;MRI检查对复杂性肛瘘的管腔和管壁大多能较好地显示,肛瘘的感染范围和空间信息也较准确,两者在诊断上各具优势。结论:根据患者诊断需求及术前判断来选择检查方法,MSCT更适合指导手术操作,而MRI则利于术后疗效随访,相互不可取代。

Objective： To compare complex anal fistula images under multi-slice spiral CT（MSCT） and magnetic resonance imaging（MRI）, and provide the evidence for clinical diagnosis. Methods： 24 cases of patients with complex anal fistula who underwent surgical treatment from July 2015 to April 2016 were analyzed retrospectively. All patients had MSCT and contrast-enhanced spiral computed tomography, and MRI. The CT and MRI features of the patients with complex anal fistula were observed and compared with each other. Results： The location, shape, number and branch of the anal fistula were consistent with the operation results, and the accuracy rate of MSCT was 100%. MRI examination showed that the lumen and the wall of the anal fistula were well displayed, and the infection range and spatial information of anal fistula were more accurate. They both had advantages in diagnosis. Conclusion： Based on patient needs and preoperative diagnosis to determine the choice of inspection methods, MSCT is more suitable for surgical guidance, and MRI is more conducive to postoperative follow-up, irreplaceable.
