使用3D-CTBA测量血栓体积与肺动脉体积比率的新型定量方法显示,急性肺栓塞 (APE) 患者的风险分层具有前景. 这一比率与现有的标记器相对应得很好,并提供了可能比Qanadli得分更准确的评估.
科学领域:
- 放射学 放射学是一门学科.
- 心脏病学 心脏病学
- 肺部医学 肺部医学
背景情况:
- 目前的急性肺栓塞 (APE) 严重程度评估依赖于复杂的方法,如使用生物标志物或RV功能指标的sPESI.
- 计算机断层扫描肺血管造影 (CTPA) 是APE诊断的标准,但Qanadli得分的准确性有限.
- 需要更简单,更准确的定量方法来分层APE风险.
研究的目的:
- 评估使用3D-CTBA在APE患者的定量风险分层的可行性.
- 为了评估血栓体积与肺动脉体积比率在风险分层方面的预测效果.
主要方法:
- 对接受CTPA的61名APE患者的回顾性分析.
- 3D-CTBA重建以计算血栓体积与肺动脉体积比率.
- 与Qanadli分数,RV/LV比率和生物标志物 (BNP,CK-MB,D-二次体) 的相关性分析.
- 分析ROC曲线以确定预测效率.
主要成果:
- 血栓体积与肺动脉体积的比率与Qanadli得分有很强的相关性 (r=0.732).
- 该比率与RV/LV比率,BNP和CK-MB有适度的相关性,与D-二次数有弱相关性.
- 在ROC分析中,该比率的AUC为0.847,而Qanadli得分为0.811.
结论:
- 来自3D-CTBA的血栓体积与肺动脉体积比是APE风险分层的一个可靠的定量方法.
- 这种定量方法可以补充或取代临床实践中的Qanadli分数.
- 3D-CTBA为APE患者提供了更准确的定量评估.

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...
