概括
在MRI上检测到的乳腺病变的第二次超声波 (SL-US) 发现显示出对焦点和质量的尺寸和形态的良好一致. 然而,MRI发现通常更可疑,指导活检决策.
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:
- 乳腺磁共振成像 (MRI) 对于检测恶性病变非常敏感.
- 第二次超声波 (SL-US) 用于评估MRI检测到的病变.
- 组织学确认是乳腺损伤诊断的黄金标准.
研究的目的:
- 为了比较SL-US和MRI检测到的乳腺病变之间的大小,形态和怀疑水平.
- 评估SL-US和MRI之间发现的一致性.
- 确定最佳的成像模式,以指导活检决策.
主要方法:
- 对224名接受SL-US治疗的患者进行了235个MRI检测到的病变的观察性回顾性研究.
- 对病变大小,形态 (BI-RADS词典) 和BI-RADS类别的分析,用于MRI和US.
- 美国确定的病变与组织学确认的比较.
主要成果:
- SL-US确定了73.6%的MRI检测到的病变.
- 平均病变大小在MRI上为15.2毫米,而在美国则为9.4毫米.
- 焦点和质量的大小和形态的良好相关性;在MRI上,非质量增强看起来更大 (P=0.0001).

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...

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...
