- 放射学 放射学是一门学科.
- 医疗成像医学成像
- 头部和部成像成像 头部和部成像
背景情况:
- 扩散权重成像 (DWI) 和输液成像 (PWI) 是先进的MRI技术.
- 它们在头部和部成像中的应用正在不断发展.
- 了解当前的临床实践对于标准化至关重要.
研究的目的:
- 调查国际头部和部放射科医生关于他们使用DWI和PWI的情况.
- 识别获取,指示,分析和报告中的模式.
- 发现实施定量DWI (QnDWI) 和动态对比增强PWI (DCE-PWI) 的障碍.
主要方法:
- 一项国际在线调查分发给美国头部和部放射学学会 (ASHNR) 和欧洲头部和部放射学学会 (ESHNR) 的成员.
- 问卷集中在定性DWI (QlDWI),QnDWI和DCE-PWI在头部和部成像中的问题.
- 使用SPSS v27.27.进行描述性统计和组比较.
主要成果:
- 95.7%的机构经常获得DWI,其中92.5%的放射科医生解释QlDWI.
- 只有36.7%的人分析QnDWI,通常用于区分瘤组织学.
- DCE-PWI在53.6%的机构中获得,但缺乏在特定临床场景中的常规应用;缺乏标准化阻碍了QnDWI和DCE-PWI的采用.

4.9K
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
