纹理和色彩增强成像 (TXI) 显示在巴雷特食道 (BE) 监测中检测高度发育不良的前景. 这项试点研究发现,TXI与NBI结合实现了100%的灵敏度和NPV,在识别高风险病变方面超过了白光内镜.
科学领域:
- 胃肠病学 胃肠病学
- 内镜成像系统的成像
- 在瘤学瘤学.
背景情况:
- 食道癌,特别是腺癌及其前体巴雷特食道 (Barrett's esophagus,BE) 是一个重大的全球健康问题.
- 目前对BE的监测方法往往错过了高度发育不良,增加了进展为腺癌的风险.
- 正在探索先进的粘膜成像技术,以提高早期检测率.
研究的目的:
- 为了评估纹理和色彩增强成像 (TXI) 在检测BE监测期间的发育不良的有效性.
- 为了比较TXI与传统白光内镜 (WLE) 的诊断性能.
主要方法:
- 一项试点研究涉及50名接受内镜检查的患者进行BE评估或监测.
- 患者被随机分配,接受WLE,其次是TXI的检查,或者反之亦然,随后进行窄带成像 (NBI).
- 从可疑区域和整个BE部分收集了向和4象限活检.
主要成果:
- TXI和NBI检测到93.3%的高度发育不良或早期腺癌病变.
- 四个高度形或早期腺癌病变被WLE遗漏,但被TXI/NBI检测到.
- 与放大NBI结合的TXI显示了100%的灵敏度和负预测值 (NPV),在BE. dysplasia诊断中具有84.6%的特异性.
结论:
- TXI是一种可行的高级粘膜成像模式,用于BE监测.
- TXI和NBI的组合显示出有可能改善BE的发育不良检测率.
- 需要进行更大规模的多中心研究,以统计比较TXI与现有的成像方法.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
