The aim of this study was to compare the accuracy of narrow - band imaging ( nbi ) , a new imaging technique , with standard colonoscopy for the detection of neoplasia in patients with longstanding ulcerative colitis 窄带成像( nbi )为检测的新技术,本研究目的是比较该技术与常规结肠镜对长期溃疡性结肠炎患者检出肿瘤的准确性。
The new test , which looks for cancer - related proteins in the blood , identifies colon cancer and precancerous polyps almost as well as a colonoscopy , according to a study published in the journal cancer research 据癌症研究杂志发布的一则研究表明,这项新的检测为在血液中寻求癌症相关蛋白,其确定结肠癌以及癌前期息肉几乎等效于结肠镜检。
Conclusions : the sensitivity of the studied first - generation nbi system for the detection of patients with neoplasia seems to be comparable to conventional colonoscopy , although more suspicious lesions were found during nbi 结论:检测患者肿瘤形成的第一代窄带成像技术的诊断敏感性与常规结肠镜具有可比性,即使该技术发现较多肿瘤可疑区。
Several screening methods are available . the use of colonoscopy examines the entire colon with high accuracy and if polyps are found , they can be safely removed . in the united states and western countries , screening with the use of colonoscopy is one standard practice 目前普查有多种不同的方法,使用能直接观察结肠内壁的结肠内视镜(大肠镜)作普查已为美国及西方国家普遍采用;但是此方法能否适用于亚洲地区则尚待探讨。
