概括
与查肝细胞癌 (HCC) 的超声波相反,发现了一些额外的病变,但其在低至中等风险的肝硬化患者中检测隐藏的HCC的总值很低.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 诊断成像 诊断成像 诊断成像
- 在瘤学瘤学.
背景情况:
- 建议进行查超声波检测肝细胞癌 (HCC).
- 一些HCC病变可以在灰度超声波成像上错过.
- 与对比度增强的超声波 (CEUS) 可以改善病变的检测.
研究的目的:
- 为了评估是否添加超声波对比度 (硫甲) 查超声波的HCC可以识别更多的HCC病变比单独的灰度成像.
主要方法:
- 对HCC查超声波与对比的回顾性分析.
- 只有在对比剂 (OAC) 给药后才能看到的病变的识别.
- 对OAC病变的后续成像和病理学的审查.
主要成果:
- 在230名患者中,有18名患者 (7.8%) 患有OAC病变.
- 在OAC中确定了一个LIRADS M病变和一个平淡的门静脉血栓.
- 在OAC病变的随访中没有发现任何额外的HCC; LIRADS 4病变被降级.
结论:
- 对比补充发现了一些额外的病变,包括门静脉血栓和高度恶性瘤.
- OAC病变的低发病率和低恶性病变率表明,在低至中等风险的肝硬化患者群体中,隐性HCC检测的价值很低.

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
