JCC: 静脉注射造影剂在克罗恩病活动超声评估中的作用

2019-05-07 不详 MedSci原创

据报道,对比增强超声[CEUS]在使用内窥镜检查作为参考标准预测疾病活动方面优于彩色多普勒成像[CDI]。本项研究的目的是确定患有克罗恩病[CD]的患者,在CEUS检查之前进行CDI检查是否有助于确定何时注射造影剂而不减少CEUS的诊断效能。

背景和目的
据报道,对比增强超声[CEUS]在使用内窥镜检查作为参考标准预测疾病活动方面优于彩色多普勒成像[CDI]。本项研究的目的是确定患有克罗恩病[CD]的患者,在CEUS检查之前进行CDI检查是否有助于确定何时注射造影剂而不减少CEUS的诊断效能。

方法
总共有180名CD患者接受了结肠镜检查和超声检查,包括CDI和CEUS评估。研究人员还构建了ROC曲线以确定曲线下面积和最佳截止值以及超声增强值以区分内窥镜活动和非活动疾病。

结果
不同分析的对比结果显示,单独CDI 的准确性达72.7%。CEUS的使用显着改善了活动性疾病的诊断:单独CEUS正确分类了180例患者中的164例[91.1%]。CDI 2级或3级患者显示出97%的预测阳性值来检测疾病活动,类似于CEUS [100%]。

结论
CEUS是内镜疾病活动最可靠的超声标准。然而,使用造影剂可能不适合评估CDI 2/3级患者的疾病活动。

JCC: 腔内对比增强超声可用来高效检测克罗恩病脓肿相关的穿透性病变

穿透性病变是克罗恩病[CD]常见的并发症。确定瘘管的存在和位置对于确定适当的治疗策略是至关重要的。本项研究的目的是评估腔内对比增强超声[IC-CEUS]用于检测CD患者脓肿相关的瘘管准确性。
