Value of MRI Ga fistulography combined with DCE-MRI in the diagnosis of high complex anal fistula with small branch fistula and orificium fistulae
Objective:To diagnoze complex high anal fistula by combined use of MRI Ga fistula radiography and dynamic contrast enhanced MRI(DCE-MRI) and to explore its guiding significance for the diagnosis and treatment of high complex anal fistula. Methods:MRI confirmed 264 cases of high complex anal fistula complicated with small internal fistula,and uncleared branch fistula form December 10,2014 to December 10,2016. DCE-MRI check was firstly performed,than DCE-MRI and GA-DTPA 4 mL+ saline 16 mL in the fistula was soon performed through injection. Youden index and AUC test were performed to test the specificity and sensitivity of the results. Results:Fistulography+DCE-MRI clear displayed fistulography of high complex fistula,external fistula,branch fistula,and fistula T1WI;T2WI showed high signal. Abscess was irregular or horseshoe shaped,T1WI,slightly low signal,T2WI,high signal of fat suppression. The control results of surgery showed that fistulography+DCE-MRI obviously increased the diagnostic value for small fistula and small branch fistula. MRI scan for small fistula showed that Youden index was 31.60%,curve area was 0.576;MRI scan for small branch fistula showed that Youden index was -23.70%,and curve area was 0.176. DCE-MRI for small fistula showed that Youden index was 69.40% and curve area was 0.603;DCE-MRI for small branch fistula showed that Youden index was -4.80% and curve area was 0.201. Fistulography+DCE-MRI for small fistula showed that the Youden index was 87.80%,and curve area was 0.798;fistulography+DCE-MRI for small branch fistula showed that Youden index was 79.50% and curve area was 0.898. Conclusion:Fistulography+DCE-MRI have high clinical significance in the diagnosis and treatment of high complex anal fistula.
