动脉旋转标记 (ASL) MRI有效监测肺栓塞 (PE) 患者在抗血栓治疗后的肺 perfusion 变化. 观察到输液改善,残留缺陷与持久性呼吸障碍有关.
科学领域:
- 放射学和成像科学 放射学和成像科学
- 心血管和呼吸系统医学
背景情况:
- 肺栓塞 (PE) 是一种影响肺 perfusion 的严重疾病.
- 监测PE治疗反应对于患者的治疗结果至关重要.
研究的目的:
- 评估动脉旋转标记 (ASL) MRI,以评估PE患者在抗血栓治疗期间的肺 perfusion 变化.
- 为了将成像发现与临床参数 (如呼吸障碍) 相关联起来.
主要方法:
- 一项前性研究,涉及107名涉嫌PE的参与者.
- 使用心电学触发的伪连续ASLMRI在1.5T的肺 perfusion 成像.
- 输液缺陷的定量评估,使用五分尺度和组图分析.
主要成果:
- 所有15名已确认的PE参与者在基线显示 perfusion 缺陷.
- 治疗后肺输液显著改善 (平均增加52%,P<.001).
- 剩余输液缺陷与持续性呼吸不良 (P = .008) 相关.
结论:
- 在PE中,ASLMRI是监测PE抗血栓治疗后肺 perfusion 恢复的可行工具.
- 图像检测结果可以提供有关症状持续性的预后信息.

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...
