持续的左上静脉,一种先天性异常,在COVID-19后缺氧的肺 perfusion scintigraphy中偶然发现. 这一案例凸显了自适应成像在核医学中解释意想不到的血管发现的重要性.
科学领域:
- 心血管成像 - 心血管成像
- 核医学就是核医学.
- 遗传异常是一种先天性异常.
背景情况:
- 肺 perfusion 扫描对于肺栓塞的诊断至关重要.
- 在这些扫描中可以检测出意想不到的血管异常.
- 持续的左上静脉 (PLSVC) 是一种罕见的先天性异常.
研究的目的:
- 报告在肺 perfusion scintigraphy 中偶然发现的PLSVC.
- 为了说明核医学在识别血管异常方面的诊断实用性.
- 为了强调对自适应成像技术的需求.
主要方法:
- 肺 perfusion scintigraphy 在一个患有COVID-19后缺氧的患者中进行.
- 采用了双位射线追踪器注射.
- 用SPECT/CT进行确认和详细的解剖评估.
主要成果:
- 在肺 perfusion scintigraphy 过程中偶然检测到持续的左上 vena cava.
- 通过双部位注射和SPECT/CT证实了PLSVC.
- 这种异常可能导致右向左的分流,绕过肺循环.
结论:
- 持续的左上 vena cava 可以偶然使用肺 perfusion scintigraphy 识别.
- 核医学成像需要适应性技术来解释非典型的血管发现.
- 准确的解释对于患者管理至关重要,特别是在缺氧的情况下.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Radiological Investigation II: MRI and Ventilation Perfusion Scan
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...
