摘要

肺灌注评估是诊断和监测各种呼吸系统疾病的关键。MRI灌注提供了一种无辐射技术,使其成为年轻人群纵向成像的理想选择。本文综述了MRI灌注的技术和应用,包括对比增强(CE) MRI和非CE方法,如动脉自旋标记(ASL)、傅立叶分解(FD)和超极化129-氙(129-Xe) MRI。ASL利用内源性水质子作为示踪剂进行肺灌注的无创测量,而FD提供肺灌注和通气的同时测量,从而能够生成通气/灌注图。超极化129-Xe MRI成为评估肺部区域气体交换的新工具。尽管MRI灌注技术前景光明,但挑战依然存在,包括与其他成像技术的竞争,以及需要额外的验证和标准化。在囊性纤维化和肺癌等疾病中,MRI显示出令人鼓舞的结果,而在慢性阻塞性肺病等疾病中,仍需要进一步验证。总之,尽管MRI灌注技术在全面、无创地评估肺功能和灌注方面具有巨大的潜力,但其更广泛的临床应用取决于技术进步、合作研究和严格的验证。
