概括
低剂量双能量CT可以预测高风险的食道静脉动脉在肝硬化患者使用脏血液动力学参数. 这种非侵入性方法为更好的临床管理提供了准确的评估.
科学领域:
- 放射学 放射学是一门学科.
- 医疗成像医学成像
- 肝病学 肝病学是一种肝病学.
背景情况:
- 食道静脉 (EV) 是肝硬化的一个严重并发症.
- 预测高风险食道静脉瘤 (HREV) 的非侵入性方法对于患者管理至关重要.
- 目前的预测方法可能缺乏准确性或需要侵入性程序.
研究的目的:
- 为了评估从低剂量一站式双能量和 perfusion CT (LD-DE&PCT) 来得出的脏血液动力学参数在预测肝硬化患者的HREV中的有效性.
- 建立一个非侵入性成像生物标志物用于HREV风险分层.
主要方法:
- 对经过LD-DE&PCT的EV肝硬化患者的回顾性分析.
- 获得脏的度和 perfusion 参数.
- 后勤回归分析以确定HREV的预测因素并构建一个预测模型.
主要成果:
- 在非HREV和HREV组之间观察到门度 (PIC),血流 (BF),通透面 (PS),体积 (V-S),总度 (TIC) 和体总血量 (BV-S) 的显著差异.
- 在单变量分析中,TIC显示了最高的预测值 (AUC=0.87).
- 确定了PIC,PS和BV-S作为HREV的独立风险因素.
- 后勤回归模型实现了HREV预测的AUC为0.93.
- 平均辐射剂量为20.66 ± 4.07 mSv.

01:24Esophageal Varices-I: Introduction
104
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

57
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
