Abstract:
Objective To evaluate the feasibility of CEUS in Crohn discasc (CD) activity.Methods Thirty-nine patients with CD were analyzed.The clinical disease activity index of 18 cases were less than 150 (inactivity),and 21 cases were between 150 and 450 (activity).The thickness of intestinal walls were measured and Limberg classification were determined by power-Doppler results.The CEUS was performed,and the parameters including rise time,peak intensity,mean transit time,time from peak to one half,wash in slope and time to peak were statistical analyzed.Results The thickness of the lesions,peak intensity and wash in slope of activity CD were greater than those of inactivity CD,which had significant difference (all P＜0.05).The Limberg classification of type Ⅰ was 1 case,type Ⅱ was 4 cases,type Ⅲ was 10 cases and type Ⅳ was 6 cases in activity CD.The Limberg classification of type Ⅰ was 10 cases,type Ⅱ was 7 cases and type Ⅲ was 1 case.The Limberg classification were mainly type Ⅲ and type Ⅳ in activity CD,and type Ⅰ and type Ⅱ in inactivity CD,which had significant difference (P＜0.001).Conclusion CEUS can provide quantitative parameters in CD activity and has great clinical value.
