Application Value of High-Resolution MRI in the Diagnosis and Typing Identification of Anal Fistula
Objective To explore the application value of high-resolution MRI in the preoperative diagnosis and typing identification of anal fistula.Methods All 50 patients with anal fistula underwent high-resolution MRI examination.The value of MRI in the diagnosis of anal fistula and the identification of anal fistula typing was analyzed based on the surgical results.Results The accuracies of MRI in the diagnosis of anal fistula internal orifice,main fistula,anal fistula branch,anal fistula external orifice and abscess were 94.55％,94.00％,83.33％,100.00％and 100.00％,respectively.The accuracies of MRI in differentiating intersphincteric type,transsphincteric type,suprasphincteric type and extrasphincteric type were 95.65％,93.75％,100.00％and 100.00％,respectively.Conclusions High-resolution MRI has high accuracy in the diagnosis of anal fistula,and can better identify the typing of anal fistula.
