概括

多模态大语言模型 (M-LLMs) 与内镜师在分类结直肠多形状方面相匹配,但难以区分座状和脚状病变. 需要对M-LLM进行进一步的开发,以可靠地支持多形态评估.

科学领域:

胃肠病学胃肠病学
人工智能的人工智能
医疗成像医学成像

背景情况:

准确的结直肠息肉形态报告对于患者管理至关重要.
使用巴黎分类的当前报告方法往往缺乏准确性.
多模式大语言模型 (M-LLM) 显示了改善形态评估的潜力.

研究的目的:

为了评估M-LLM (GPT-4o) 在分类结直肠多形态中的准确性.
为了比较M-LLM的表现与专家和非专家内镜师.
评估M-LLM能够区分多型和非多型的病变以及型和脚型病变的能力.

主要方法:

利用了100个结肠镜视频与巴黎分类标签的SUN数据集.
一个M-LLM (GPT-4o) 分类了每次损伤的五个.
专家和非专家内镜师独立地对相同的病变进行了分类.

主要成果:

在区分非多聚体和多聚体病变方面,M-LLM的准确率为73%,与专家 (75%) 和非专家 (77%) 相比.
M-LLM在区分形病变和形病变的准确性为55%,明显低于专家 (76%) 和非专家 (77%).
与专家 (82%) 和非专家 (88%) 相比,M-LLM在区分形和形病变方面的特异性很差 (12%).

结论:

在区分非多聚体和多聚体结直肠病变方面,M-LLMs表现出与内镜师相似的性能.
目前,M-LLM无法可靠地识别脚形态,这表明需要进一步改进.
这些发现表明,M-LLM可能有助于评估多形态,但需要对特定分类进行改进.

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:
