概括
定量微血管性成像 (qMI) 显示了识别高风险甲状腺结节的潜力. 高血管度可能表明小恶性瘤,但qMI与结节大小和细胞学相关性较弱.
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:
- 甲状腺结节很常见,准确的风险分层对于患者管理至关重要.
- 区分良性和恶性结节通常依赖于成像特征和细胞学.
- 定量微血管性成像 (qMI) 提供了一种评估结节血管性的新方法.
研究的目的:
- 评估超声波qMI在识别高风险甲状腺结节方面的能力.
- 评估计算机辅助诊断 (CAD) 与 qMI 结合的诊断性能.
- 为了将qMI和CAD发现与细胞学结果相关联.
主要方法:
- 一项前性单中心研究包括165个甲状腺结节.
- 使用欧盟TIRADS分类的CAD和qMI (血管性指数-VI) 来评估结节.
- 进行了细针吸收活检和细胞检查,结果作为参考标准.
主要成果:
- 平均结节大小为15.6毫米;平均VI为29.03%.
- 良性/低风险结节 (TIR2-3A) 的平均VI比高风险/恶性结节 (TIR3B-5) 的平均VI高 (35%) (24.2%,p=0.04).
- 在恶性结节中,较小的结节 (<10毫米) 显示出比较大的结节 (16.91%,p=0.03) 高的VI (31.45%). CAD显示出高灵敏度和特异性.
结论:
- 血管性指数 (VI) 显示与结节大小和细胞学存在较弱的相关性.
- 高血管性可能在小型恶性和大型良性瘤中更为普遍.
- qMI可能有助于评估一些EU-TIRADS 3和4节点,其中CAD准确性有限.

Ultrasonography
6.0K
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.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
119
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
