Abstract Objective: To assess the value of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) for staging
thyroid-associated ophthalmopathy (TAO). Materials and Methods: We prospectively enrolled 56 TAO patients , and divided them into active
group (37 patients with 74 eyes) and inactive group (19 patients with 38 eyes). The minimum, mean, and maximum values of semi-quantitative
[time to peak (TTP), area under the time-signal intensity curve (AUC), maximum enhancement slope (Slope )] and quantitative [volume
max
transfer constant (K ), the rate constant (K ), fractional volume of the extravascular-extracellular space (V)] parameters were calculated and

compared between groups. Multivariate logistic regression analysis was applied to identify the independent imaging indicators of active TAO.
Receiver operating characteristic (ROC) curve analysis was used to evaluate the performance of the identified significant imaging parameters
and their combination. Results: Active patients showed significantly higher mean TTP, mean and maximum AUC, mean and maximum V than
e
inactive patients (P<0.05). Maximum AUC and mean V were found to be independent variables for determining the disease activity (P=0.030,
e
0.014, respectively). The area under ROC curve of active TAO was 0.689 and 0.673, respectively, using the maximum AUC and the mean Ve
values. Combination of two parameters could determine the active TAO with optimal performance (area under the ROC curve 0.731).
Conclusions: DCE-MRI-derived semi-quantitative and quantitative parameters are all useful for determining the activity of TAO. The model
combining maximum AUC and mean V can effectively help to stage the patients with TAO.
