摘要目的综合评估CT、MRI、US以及闪烁成像技术对活动期克罗恩病的分级。方法在MEDLINE、EMBASE、Cochrane数据库中搜索,1983年1月—2014年3月间,关于应用CT、MRI、US以及闪烁成像技术评估活动期克罗恩病的分级并与内镜检查、活组织检查以及术中所见相对照的研究。由2位分析者独立对数据进行评估。把所有研究的数据建立3×3表格(无,轻微,明显疾病),进行活动期克罗恩病分级的准确性评估,通过确定的或随机的效果模式计算/总结 Abstract Objective To evaluate the classification of active Crohn’s disease by CT, MRI, US and scintigraphy. Methods The MEDLINE, EMBASE, and Cochrane databases were searched. From January 1983 to March 2014, the classification of active Crohn’s disease was evaluated using CT, MRI, US and scintigraphy techniques and compared with endoscopy, Examination and intraoperative findings relative to the study. The data was independently evaluated by 2 analysts. Establish 3 × 3 tables for all study data (no, minor, overt disease), assess the accuracy of classification of active Crohn’s disease, and calculate / summarize through a defined or random effect model
