食道水直径 (EVD) 与门口压力梯度 (PPG) 相对应. 人工智能增强的EVD测量显示了提高PPG的非侵入性预测因子的潜力,有助于对出血事件的风险评估.
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:
- 食道水直径 (EVD) 对于预测门高血压中出血风险至关重要.
- 目前的EVD评估依赖于主观内镜估计.
- 有限的研究存在于EVD和门压梯度 (PPG) 之间的直接相关性.
研究的目的:
- 调查EVD和PPG之间的相关性.
- 评估人工智能辅助EVD测量作为PPG的非侵入性指标的潜力.
- 评估EVD对与PPG升高相关的不良事件的预测价值.
主要方法:
- 利用了128名患有门高血压和胃食道静脉瘤的患者的回顾性和前性数据.
- 在回顾阶段使用基于AI的虚拟统治器进行EVD评估.
- 测量PPG通过放射性干预和EVD在内镜期间与AI协助在前阶段.
主要成果:
- 在PPG和EVD之间发现了显著的正相关性 (r = 0.521,P < 0.001).
- 较高的PPG水平 (≥20 mmHg) 与明显更大的EVD相关 (OR = 29.275,P < 0.001).
- 人工智能辅助的EVD测量显示,在诊断PPG水平可能超过20mmHg时,EVD>1.1厘米时,准确度为0.814.
结论:
- 埃博拉病毒与PPG有很强的正相关性.
- 人工智能增强的EVD测量是评估PPG的一个有希望的非侵入性标记.
- 这些发现为在临床环境中进行非侵入性PPG评估提供了新的途径.
