PDFAbstract
Objective To investigate the diagnostic accuracy and value of 1.5T MRI multiple sequence anal fistula. Methods The clinical data of 32 cases diagnosed by MRI from 2013.1 to 2018.5 were analyzed. Results Among 32 cases of anal fistula, 42 were fistulas, 46 were internal canals, 42 were external canals, and fistulas were strips. The T1WI showed equal or low signal, T2WI-fs showed high signal, and DWI showed high signal. Among them, 3 cases were enhanced. The MRI sensitivity of the fistula, internal and external ports was 88.1%, 89.1%, and 92.9%, respectively. There was no statistical difference between the 1.5T MRI diagnosis and pathology (P>0.05). Conclusion MRI has a good indication of the fistula, the internal orifice and the external orifice, and has guiding significance for the operation.
