Multimodal magnetic resonance imaging sequences for diagnosis of anal fistula
[Objective]To investigate the diagnostic efficacy of magnetic resonance imaging(MRI)in anal fistula under multimodal conditions.[Methods]A retrospective analysis was conducted on 73 anal fistula patients admitted to Xiaogan Hospital Affiliated to Wuhan University of Science and Technology from January 2018 to August 2022.All patients underwent MRI plain and enhanced scans before surgery.Using the surgical results as a reference,the diagnostic efficacy of different MRI sequences for anal fistula was analyzed.[Results]Compared with clinical classification and Parks classification,the kappa values were 0.815 and 0.856,respectively,indicating good consistency with surgical results.Among the 98 internal fistula openings and 126 fistula tracts,the accuracy rates were 93.33％and 94.74％,respectively.Under multimodal sequences,there were significant differences in the diagnosis of internal fistula openings and tracts compared with single sequences(P＜0.05).[Conclusion]MRI under multimodal conditions has better diagnostic efficacy for anal fistula,especially in displaying small internal openings and fistula tracts,and can provide reliable basis for preoperative evaluation.This can effectively help clinicians to solve the lesion problem for anal fistula patients.
