摘要:
目的 研究磁共振扩散加权成像（DWI-MRI）联合动态对比增强磁共振成像（DCE-MRI）对肛瘘的诊断评估价值。方法 以2019年1月-2022年12月龙南市第一人民医院接诊的106例疑似肛瘘患者为研究对象，给予DWI-MRI与DCE-MRI检查，分析DWI-MRI、DCE-MRI及二者联合对肛瘘的诊断价值，观察其影像学表现，对比其在肛瘘检出及分型中的作用。结果 DWI-MRI与DCE-MRI检查的影像学表现存在一定差异；DWI-MRI联合DCE-MRI对肛瘘的诊断敏感度、特异度、准确性、阳性预测值、阴性预测值均高于两者单独检测（P＜0.05）；DWI-MRI联合DCE-MRI对肛瘘内口、外口、分支的检出率高于单独检测（P＜0.05）；DWI-MRI联合DCE-MRI对肛瘘分型的诊断符合率高于两者单独检测（P＜0.05）。结论 DWI-MRI联合DCE-MRI对肛瘘的诊断价值高于二者单独检测，在肛瘘检出及分型方面均具有一定优势。
Abstract:
Objective To study the value of diffusion weighted magnetic resonance imaging (DWI-MRI) combined with dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in the diagnosis and evaluation of anal fistula.Methods A total of 106 patients with suspected anal fistula who were admitted to the First People ’s Hospital of Longnan from January 2019 to December 2022 were enrolled in the study. DWI-MRI and DCE-MRI were performed to analyze the diagnostic value of DWI-MRI, DCE-MRI and their combination for anal fistula. The imaging findings were observed and their roles in the detection and classification of anal fistula were compared.Results There were some differences in imaging findings between DWI-MRI and DCE-MRI. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of DWI-MRI combined with DCE-MRI in the diagnosis of anal fistula were higher than those of the two alone (P<0.05). The detection rate of internal opening, external opening and branch of anal fistula by DWI-MRI combined with DCE-MRI was higher than that by single detection (P<0.05). The diagnostic coincidence rate of DWI-MRI combined with DCE-MRI for anal fistula classification was higher than that of the two alone (P<0.05).Conclusion The diagnostic value of DWI-MRI combined with DCE-MRI for anal fistula is higher than that of the two alone, and it has certain advantages in the detection and classification of anal fistula.
