使用基于探头的共聚焦激光内微镜 (pCLE) 的自动系统准确地评分性结肠炎 (UC) 炎症. 这种工具可以预测患者的复发和预后,改善UC管理超出传统内镜.
科学领域:
- 胃肠病学 胃肠病学
- 医疗成像医学成像
- 人工智能的人工智能
背景情况:
- 性结肠炎 (UC) 中的持续性炎症与复发和不良结果有关.
- 与传统内镜相比,基于探针的共聚焦激光内显微镜 (pCLE) 提供了优越的UC炎症评估.
研究的目的:
- 开发和验证使用pCLE的UC炎症活动的自动严重程度分级系统 (ASGS).
- 评估ASGS对UC复发和预后的预测能力.
主要方法:
- 开发了一个基于卷积神经网络 (CNN) 的ASGS,用于回顾性PCLE图像分级.
- 通过UC患者的PCLE图像和视频进行ASGS的前性验证.
- 与病理发现相关的ASGS分级和监测患者在12个月内复发.
主要成果:
- 在图像 (97.38% - 99.90%) 和视频 (75.56% - 98.17%) 数据集中对ASGS的高度敏感性和特异性,用于对UC炎症活性进行分级.
- ASGS与病理学有很强的相关性 (QWK=0.780).
- 与白光内镜 (WLE) 相比,ASGS的内显微镜得分是UC复发的优异预测器.
结论:
- 通过PCLE,ASGS提供完全自动化,准确的UC炎症活性分级.
- 该系统有可能预测UC缓解,并改善患者的预后.
- 基于PCLE的ASGS在UC管理和监控方面取得了重大进展.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
