概括
超声波组织散射分布成像 (TSI) 在特征焦点肝病变 (FLLs) 中取得了很高的成功,补充了剪切波弹性成像 (SWE). 当SWE测量不可行时,TSI提供了可靠的替代方案,改善了FLL诊断.
科学领域:
- 医疗成像医学成像
- 定量超声波检查是什么
- 肝病学 肝病学是一种肝病学.
背景情况:
- 焦点肝病变 (FLL) 是常见的,需要准确的良性与恶性差异化.
- 剪波弹性图 (SWE) 是用于FLL评估的标准超声波技术.
- 超声波组织散射分布成像 (TSI) 是一种使用纳卡加米分布进行组织表征的新方法.
研究的目的:
- 探索 TSI 在描述 FLL 的潜力.
- 为了比较 TSI 与 FLL 的 SWE 的诊断效果.
- 评估 TSI 作为肝损伤评估的补充工具.
主要方法:
- 展望研究涉及235名参与者 (265名FLL),采用B模式,SWE和STI数据采集.
- 用于性能评估的接收器操作特征曲线 (AUROC) 下的面积.
- 验证组 (20个FLL) 评估了STI的切断效率.
主要成果:
- TSI在FLL测量中实现了100%的成功率,而SWE的成功率为49.43%.
- 当SWE成功时,TSI和SWE显示了可比的AUROC (0.83对0.84).
- 当SWE出现故障时,TSI的AUROC为0.78,整体AUROC为0.81.
结论:
- 超声波 TSI 是一个有前途的工具来描述FLLs.

4.5K
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.

237
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...
