肺高血压在结核病摧毁肺 (TDL) 患者中很常见. 人工智能 (AI) CT成像,测量损坏的肺体积 (VTDLT),有助于诊断TDL中的肺高血压 (PH).
科学领域:
- 肺部病理学 肺部病理学
- 放射学 放射学是一门学科.
- 心脏病学 心脏病学
背景情况:
- 结核病摧毁肺部 (TDL) 是结核病的严重后果.
- 肺高血压 (PH) 可以使TDL复杂化,影响患者的预后.
- 在TDL患者中准确诊断PH具有临床意义.
研究的目的:
- 调查TDL患者PH的临床特征.
- 评估人工智能 (AI) CT成像在TDL中诊断PH的实用性.
- 探索破坏的肺体积和肺血液动力学之间的关系.
主要方法:
- 对51名TDL患者的回顾性分析,根据右心导管治疗,分类为具有PH的TDL (n=31) 和没有PH的TDL (n=20).
- 以人工智能为基础的胸部CT数据的重建,细分和染,以计算肺体积参数.
- 两组之间的临床,血液动力学和肺体积数据的比较.
主要成果:
- 与非TDL对照组 (22.64%) 相比,TDL患者的PH患病率 (61.82%) 显著更高.
- 在肺功能,血液动力学参数 (PCWP/PVR,PASP/TRV) 和损坏的肺组织总体 (VTDLT) 中观察到显著差异.
- VTDLT显示出与平均肺动脉压 (mPAP) 的正相关性,并且基于人工智能CT的综合诊断模型 (VTDLT + PSAP) 在PH检测方面实现了高灵敏度 (90%) 和特异性 (88.9%).
结论:
- 患有PH的TDL患者经常出现限制性肺部疾病.
- 损坏的肺组织体积 (VTDLT) 是一个可靠的指标,与mPAP正相关.
- 人工智能衍生的VTDLT,结合心声学估计的PASP,为诊断TDL患者的PH提供了宝贵的工具.
