双弹性弹性学超声波 (DEUS) 有效地分阶段代谢功能障碍相关的脂肪性肝病 (MASLD). 这种非侵入性工具可以准确地识别疾病进展和晚期纤维化,为现有方法提供了优越的替代方案.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 医疗成像医学成像
- 机器学习 机器学习
背景情况:
- 代谢功能障碍相关的脂肪性肝病 (MASLD) 诊断是复杂的,二进制方法错过了其全谱.
- 双弹性体超声波 (DEUS) 是一种用于MASLD分期的新型弹性体技术.
研究的目的:
- 评估DEUS在区分MASLD不同阶段的疗效.
- 开发和验证一个机器学习模型 (ModelDEUSC),集成DEUS和用于MASLD分层的临床数据.
- 为了比较模型DEUSC的诊断准确性与其他针对晚期纤维化的非侵入性测试.
主要方法:
- 一项前性多中心研究,涉及312名患者进行导出和135名患者进行验证.
- 患者接受了DEUS扫描,肝脏活检和实验室测试.
- 十个机器学习算法被用来开发模型DEUSC,结合DEUS和临床参数.
主要成果:
- 模型DEUSC在验证队列中实现了MASLD三元分类的0.858的宏观平均AUC.
- 诊断MASH晚期纤维化 (≥F3) 的AUC为0.886,表现优于FAST,FIB-4,NFS和APRI.
- 模型DEUSC在分期肝纤维化,炎症和肥胖症方面表现出强的表现,不受糖尿病或肥胖的影响.
结论:
- DEUS提供了用于MASLD连续分层的先进功能.
- 模型DEUSC为MASLD管理提供了一个低成本,可访问和准确的非侵入性工具.
- 这项技术有可能显著改善MASLD的非侵入性评估.

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
