- 医疗成像医学成像
- 超声波技术 超声波技术 超声波技术
背景情况:
- 炎症性肠病 (IBD) 需要非侵入性方法来评估疾病活动.
- 肠道超声波 (IUS) 显示出有希望的结果,利用肠壁厚度和多普勒信号等参数.
- 在IBD的IUS中超级微血管成像 (SMI) 的诊断价值尚未明确.
研究的目的:
- 为了评估SMI的诊断准确性,在评估性结肠炎 (UC) 中的疾病活性时使用IUS.
- 将SMI的性能与传统的多普勒成像和已建立的疾病活动得分进行比较.
- 为了确定SMI是否改善了UC患者内镜缓解的预测.
主要方法:
- 一项前性,单中心,横截面研究包括62名UC患者.

4.3K
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.

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.

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...
