Synopsis

Keywords: Pelvis, Diffusion/other diffusion imaging techniquesTo assess the image quality of anal fistula by RESOLVE DWI compared to SS-EPI DWI, and explore the value of RESOLVE DWI for diagnosis and classification of anal fistula. Qualitative and quantitative evaluation of image quality showed that RESOLVE DWI group was superior than SS-EPI DWI group.The accuracy of RESOLVE DWI sequence in the diagnosis of the internal orifice, branch fistula, and classification was higher than in SS-EPI DWI for anal fistula. RESOLVE DWI can provide higher quality images of anal fistula than SS-EPI DWI.
