摘要
目的对比研究多排螺旋CT结肠成像变换体位扫描在检查结肠息肉性病变的应用价值。方法收集2011年3月-2015年12月共39例具有同期常规结肠镜检和多排螺旋CT结肠镜成像术检查患者,每例患者在CC检查前不超过2周时间内都进行了HD750 CTC检查,以CC检查为标准共发现189枚结肠息肉,其中28例135枚息肉在CC检查过程中进行了电凝切除及病理。全部病例CTC检查均采用仰卧位和俯卧位两个体位进行检查。结果单独仰卧位CTC检查发现了203枚结肠息肉性病变,而单独俯卧位发现了199枚。联合仰卧位和俯卧位图像评估共发现185枚结肠息肉性病变,与CC检查结果基本相符,所遗漏的4枚结肠息肉均为直径小于5mm病变。结论多排螺旋CT结肠成像变换体位扫描(仰卧位和俯卧位双体位扫描)在筛查结肠息肉性病变具有很高的敏感度,与金标准CC检查结果大致相符,完全能够满足临床诊断要求,可以为及时有效的治疗及预后随访提供准确可靠的影像依据。
Objective To evaluate the study value of positional change multi-slices helical CT Colonography in colorectal polyps. Methods Total 189 polys in 39 cases were perforated with conventional Colonoscopy and underwent multi slices helical CT Colonography between two weeks. The CT Colonography screening in both supine and prone position.Results All the 39 cases showed 203 polys in supine position and 199 polys in prone position scaned. 185 polys is noted by combined evaluation when change positional screening in both supine and prone positions, 4 polys size〈5nml were nfissing, Conclusion MS CTC screening in change positional is excellent sensitivity, and specificity for colorectal polys, which can provide more accurate infomlations for clinical diagnosis and treatment.
