Table 3. Fistulas Number Depicted by Each Magnetic Resonance Modality and Corresponding Sensitivitya.
T2WI Alone | DWI Alone | T2WI + DWI | |
---|---|---|---|
Number of fistula detected | 50/56 | 54/56 | 56/56 |
Sensitivity | 89.3% (77.4 - 95.6) b | 96.4% (86.7 - 99.4) b | 100% (90 - 100) c |
aAbbreviations: DWI, diffusion weighted imaging; T2WI, T2-weighted imaging.
bNo statistically significant difference between T2WI alone and DWI alone was found. (P = 0.289, Fisher’s exact test) Numbers in parenthesis indicate 95% CI.
cA statistically significant difference was found between combined T2WI with DWI and T2WI alone (P = 0.03).
