概括
脑血管造影可以导致静音栓塞事件,通过MRI检测到,即使没有神经缺陷. 患有血管风险因素的患者接受诊断血管造影,这些栓塞事件的发生率更高.
科学领域:
- 神经学 神经学
- 放射学 放射学是指放射学
- 血管医学 血管医学
背景情况:
- 大脑血管造影带有神经复杂症的风险.
- 血管造影后临床静音栓塞的发生率尚未得到充分确立.
研究的目的:
- 为了比较神经系统并发症的发生率与脑血管造影后静音栓塞的发生率.
- 在诊断血管造影期间调查与栓塞事件相关的因素.
主要方法:
- 扩散权重磁共振成像 (MRI) 用于检测100次脑血管造影前后的栓塞事件.
- 患者在手术前和后接受了神经学评估.
- 进行了相关性分析,以确定栓塞风险因素.
主要成果:
- 在血管造影前的MRI上没有检测到任何异常.

01:20Imaging Studies for Cardiovascular System II:Types of Echocardiography
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 diagnosing...

01:28Imaging Studies for Cardiovascular System V: CT
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
01:29Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
