在这里,我们描述了相位分辨功能性肺 MRI 作为一种不含造影剂的质子 MR 技术来评估肺通气和灌注动力学。它在不同领域优势和年龄组得到验证和适用,可以通过帮助疾病量化和治疗监测来增强未来的临床决策。

我们研究的主要目的是在整个心动周期和整个通气周期中动态可视化和量化肺通气和灌注,以便及早发现肺部疾病并量化治疗反应,最终能够帮助肺病患者的预后。最近的发展引入了通气周期的 3D 各向同性体积重建序列,产生了比 2D 协议更高的空间分辨率,从而创建了 3D PREFUL 变体。这一进步虽然意义重大,但缺乏灌注洞察力,但将 3D 和 2D 方案定位为更全面肺功能分析的补充工具。

我认为最近一年,我们在各种临床场景中使用 PREFUL MRI 取得了相当大的成功。我想指出三个。首先是慢性阻塞性肺病。

我认为我们可以非常令人信服地证明,吸入器治疗后,通气得到改善,但与此同时,我们看到肺实质灌注得到改善,VQ 匹配也有所改善。其次,肺移植。预测肺移植损失并了解患者的情况非常重要,而 PREFUL 能够做到这一点。

PREFUL 可以预测由于慢性肺移植排斥反应导致的同种异体移植功能障碍导致的未来移植丢失。最后但并非最不重要的一点是,对于儿童来说,我认为这非常重要,因为他们在肺功能测试期间经常不依从。在这里,我们可以看到并量化 CF 患儿治疗后的治疗反应。

总的来说,我认为 PREFUL MRI 正处于非常好的状态,从实验室过渡到床边。我们的方案,相位分辨功能性肺 MRI,允许使用通用的 MRI 序列进行自由呼吸成像,无需额外的硬件、造影剂或辐射。它提供回顾性图像排序,提供通气和灌注动力学的详细分析。

这种可访问性、非侵入性和全面诊断能力的结合使其有别于其他技术。未来,我们的实验室将专注于通过优化的序列协议、设计和 AI 驱动的重建技术来缩短扫描时间并提高图像质量。我们还致力于开发、完善和验证新的定量生物标志物,包括定量灌注、脉搏波速度和肺动脉压测量。
