Ultrasound II: Endoscopic Ultrasound and FibroScan

117
Endoscopic Ultrasound (EUS) and FibroScan are valuable diagnostic tools in gastroenterology and hepatology, each with specific applications and techniques.

Ultrasonography01:17

Ultrasonography

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.
During an ultrasonography procedure, a handheld device called...

The Thyroid Gland01:23

The Thyroid Gland

3.9K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

科学领域:

  • 医疗成像医学成像
  • 生物物理学的生物物理.

背景情况:

  • 弹性学评估组织弹性,应变弹性学 (SE) 和剪切波弹性学 (SWE) 是关键方法.
  • SE和SWE都补充了用于甲状腺疾病评估的传统B模式超声波.

研究的目的:

  • 审查弹性图形技术,它们的物理原理,以及它们在诊断甲状腺结节中的作用.
  • 在甲状腺结节评估中评估弹性体的诊断价值.

主要方法:

  • 选择性审查国际指导方针和关于弹性图形的最新出版物.
  • 分析弹性图像作为一个独立的方法,与B模式超声波和风险分层系统 (如TIRADS) 相比或结合.

主要成果:

  • 弹性图提供了基于剪切刚度的额外组织对比信息.
  • 通过SWE,可以进行定量评估,以补充定性SE.
  • 结合弹性图与B模式超声波和风险分层,改善了对结节的诊断准确度,细针活检结果不确定 (贝塞斯达III/IV).
  • 通过弹性图识别的软结节具有很高的负预测值,有助于风险分层.

结论:

  • 弹性扫描是评估甲状腺结节的有价值的辅助工具,特别是那些具有中间恶性瘤风险或不确定的细针吸收发现的甲状腺结节.
  • 虽然在EU-TIRADS中提到,但弹性体的整合到TIRADS等风险分层系统中是有限的,主要出现在法国TIRADS中.
  • 方法的局限性包括理想化的假设,制造商/检查员的依赖性和潜在的工件.
