概括
甲状腺结节的新型基于模式的微血管分类 (PBMC) 改善了良性和恶性结节的分化. 与当前的指导方针相比,这种多模式超声波方法减少了不必要的细针吸收 (FNA) 活检.
科学领域:
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
- 医疗成像医学成像
背景情况:
- 目前的甲状腺结节活检指南依赖于灰度超声波 (GUS) 特性,导致良性结节活检的高率.
- 需要提高诊断准确度,以减少不必要的细针吸收 (FNA) 程序.
研究的目的:
- 开发和验证一种基于模式的小血管分类 (PBMC),用于甲状腺结节.
- 创建具有预测性的多模式超声波 (US) 模型,整合GUS,微血管流量成像和剪切波弹性图像.
- 将新模型的FNA决策准确度与美国放射学学院甲状腺成像报告和数据系统 (ACR TI-RADS) 进行比较.
主要方法:
- 这是一项针对599名参与者的793个甲状腺结节 (248个良性,545个恶性) 的前性研究.
- 使用PBMC将病变分为恶性 (融合,穿刺,轮标志),良性 (戒指标志) 或其他血管模式.
- 开发并验证了多变量后勤回归和多模式的美国模型,包括GUS,Young的模量和PBMC.
主要成果:
- 恶性血管征兆与恶性瘤正相关 (OR:10.43),而良性征兆与恶性瘤相反相关 (OR:0.10).
- 多模式的美国模型在接收机操作特征曲线 (AUC) 下获得了比ACR TI-RADS (AUC 0.62) 的0.95的优越面积.
- 在71%的风险值下,多式联通美国将不必要的FNA程序减少了27%,远远超过TI-RADS (13%).
结论:
- 微血管形态模式的视觉评估增强了良性和恶性甲状腺结节之间的差异化.
- 开发的多模式美国模型显示了减少良性甲状腺结节的不必要活检的潜力.

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.

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
