概括
目前的大型语言模型 (LLM) 在测量科布角以评估脊椎形时显示出有限的准确性. 在用于脊柱形分析的临床整合之前,人工智能工具需要进一步开发.
科学领域:
- 医学成像分析分析 医学成像分析
- 医疗保健中的人工智能
- 脊柱形评估 脊柱形评估
背景情况:
- 脊柱病的严重程度是用X射线图上测量的科布角来量化.
- 人工智能 (AI) 融入临床工作流程引发了关于其在脊柱形分类中的有用性的问题.
- 在临床应用中评估领先的大型语言模型 (LLM) 的能力至关重要.
研究的目的:
- 评估四个著名的LLM (ChatGPT,Gemini,Perplexity,Grok) 在计算脊柱脊椎病X射线图中的科布角的诊断准确度.
- 将这些LLM的性能与放射科医生的测量进行比较.
- 评估AI在科布角确定中的可用性和临床适用性.
主要方法:
- 一项涉及122名脊椎病患者X射线图的横截面研究.
- 由经过培训的放射科医生使用Horos软件作为参考标准进行独立的科布角计算.
- 放射图由四名LLM分析,以识别脊椎病类型,生成叠加,并计算科布角,随后进行统计分析.
主要成果:
- 双子座和ChatGPT显示出显著的局限性,双子座未能产生测量结果,ChatGPT显示出很大的误差 (MAE 58.6° ± 45.9°).
- 困惑和Grok为所有案例提供了估计值,但平均差异分别为18.8° (±13.3°) 和24.2° (±18.3°).
- 没有AI模型能够准确地识别S形脊椎病,也没有达到科布角测量的临床可接受差异 (≤10%).
结论:
- 商业上可用的LLM目前对临床科布角测量在脊椎病的准确性不够.
- 虽然Perplexity和Grok在测试模型中表现更好,但没有一个模型达到临床上可接受的准确性.
- 开发专门的AI工具是必要的,以确保可靠的临床整合在脊柱形评估.

02:16Stereotype Content Model
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence categorization, a person will feel...
01:10Computed Tomography
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

01:27Language and Cognition
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
01:28Automatic Processing and Automatic Social Behavior
Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...
