与对比度增强的超声波 (CEUS) 在乳腺癌亚型中显示出明显的增强模式. 这种成像技术可能有助于区分三阴性乳腺癌 (TNBC) 和非TNBC,有助于患者管理.
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:
- 乳腺癌包括多种分子亚型,预后不同.
- 准确的亚型区分对于定制的治疗策略至关重要.
- 与对比度增强的超声波 (CEUS) 提供了功能性成像对瘤血管性的洞察力.
研究的目的:
- 使用CEUS.研究不同乳腺癌分子亚型的对比增强模式.
- 评估定性和定量CEUS参数在区分这些子类型的有用性.
- 探索CEUS在乳腺癌放射学-病理学相关性方面的潜力.
主要方法:
- 一项前性研究,涉及患有经遗传病理学证实乳腺癌的女性患者.
- 对所有包含的群体进行了标准B模式超声波 (USG) 和CEUS.
- 分析了定性 (增强模式,填充,冲洗) 和定量 (峰值增强,峰值时间,AUC,MTT) CEUS参数.
主要成果:
- 分析了30个乳腺质,分为三阴性乳腺癌 (TNBC) (36.7%) 和非TNBC (63.3%) 亚型.
- B模式USG显示TNBC和非TNBC之间的形状和边际有显著差异.
- CEUS揭示了TNBC病变,通常呈现为圆形,边缘有界,外围结节增强,缺少填充 (p=0.04).
- 在量化输液参数中,亚型之间没有发现显著差异.
结论:
- 乳腺癌的不同分子亚型在CEUS上表现出独特的对比度增强模式.
- CEUS在区分乳腺癌亚型,特别是TNBC方面显示出潜力.
- 这种成像模式可能有助于放射学-病理学相关性和患者随访.

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...
Ultrasound I: Abdominal Ultrasonography
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...
