目的：通过使用计算机断层扫描（CT）结肠成像或“虚拟结肠镜检查”的三种不同数据查看（显示）模式，确定放射科医生观察员检测结肠息肉的灵敏度。材料和方法：正常结肠患者的CT结肠造影数据被用作插入数字合成息肉的基础数据。将40个这样的息肉（直径为3.5、5、7和10 mm）随机插入基础数据的4个副本中。轴向CT研究，体积渲染的虚拟内窥镜电影，并从三维模式称为“全景内窥镜”的研究进行了审查盲目和独立的两个radiologist.RESULTS：检测提高息肉大小。灵敏度的趋势取决于是否考虑所有插入的病变或仅考虑可见病变，因为模式在如何完整地描绘结肠表面方面有所不同。对于两个评价者和所有7 mm或更大的息肉，全景内镜的敏感性（90%）显著高于仿真内镜（68%，P = 0.014）。仅对于可见病变，一名阅片者的灵敏度分别为85%、81%和60%，另一名阅片者的灵敏度分别为65%、62%和28%。结论：全景内窥镜显示结肠表面的图像比仿真内窥镜显示结肠表面的图像更清晰，因此全景内窥镜显示结肠表面的图像比仿真内窥镜显示结肠表面的图像更清晰。三维显示器的更高灵敏度可以证明额外的计算和查看时间是合理的。
PURPOSE:To determine the sensitivity of radiologist observers for detecting colonic polyps by using three different data review (display) modes for computed tomographic (CT) colonography, or “virtual colonoscopy.”MATERIALS AND METHODS:CT colonographic data in a patient with a normal colon were used as base data for insertion of digitally synthesized polyps. Forty such polyps (3.5, 5, 7, and 10 mm in diameter) were randomly inserted in four copies of the base data. Axial CT studies, volume-rendered virtual endoscopic movies, and studies from a three-dimensional mode termed “panoramic endoscopy” were reviewed blindly and independently by two radiologists.RESULTS:Detection improved with increasing polyp size. Trends in sensitivity were dependent on whether all inserted lesions or only visible lesions were considered, because modes differed in how completely the colonic surface was depicted. For both reviewers and all polyps 7 mm or larger, panoramic endoscopy resulted in significantly greater sensitivity (90%) than did virtual endoscopy (68%,P= .014). For visible lesions only, the sensitivities were 85%, 81%, and 60% for one reader and 65%, 62%, and 28% for the other for virtual endoscopy, panoramic endoscopy, and axial CT, respectively. Three-dimensional displays were more sensitive than two-dimensional displays (P< .05).CONCLUSION:The sensitivity of panoramic endoscopy is higher than that of virtual endoscopy, because the former displays more of the colonic surface. Higher sensitivities for three-dimensional displays may justify the additional computation and review time.
