Diagnostic value of contrast-enhanced ultrasound in the activity of idiopathic retroperitoneal fibrosis: a retrospective study

ConclusionCEUS has good diagnostic value for IRPF disease activity.Key points• Thickness and contrast-enhanced ultrasound score were significantly higher in the active group than those in inactive group (P <  0.001).• With thickness of 4 mm and contrast-enhanced ultrasound 2 score as optimal cut-off values, the sensitivity and specificity were 89.86%, 81.01% and 52.17%, 100.00%, respectively.• During follow-up, when the disease progressed, the change of CEUS score was earlier than the change of thickness.
