本研究旨在探索129Xe通气功能MRI与肺部病灶类型之间的关联．我们对143例患者进行129Xe通气功能MRI和肺部CT扫描，并分析了肺叶水平的通气功能与肺部病灶类型之间的关系．结果显示，大部分肺叶（74.6%）129Xe肺通气功能MRI和CT结果一致．通气功能损伤与CT病灶类型相关，且混合疾病和肺气肿/肺大疱更易引起肺通气功能障碍．此外，我们的研究显示不同肺部病灶类型会呈现出不同的通气模式．即129Xe通气功能MRI和肺部CT能够提供互补信息．本研究的初步结果将为肺部病灶引起的通气功能损伤评估提供数据支持，为临床影像学诊断提供更多的参考依据，有助于优化肺部疾病的诊断和治疗．

This study investigates the correlation between 129Xe ventilation functional MRI and CT-detected pulmonary lesion types. We performed 129Xe ventilation functional MRI and CT scans on a sample of 143 patients, subsequently analyzing the relationship between lung ventilation function at the lobe level and CT lesion types. The findings suggest that the ventilation function from 129Xe MRI was consistent with CT results in the majority of lung lobes (74.6%). The ventilation function impairment of lung correlates with CT lesion types, particularly in instances of mixed diseases and emphysema/bullae, which are more prone to induce lung ventilation dysfunction. Moreover, distinct ventilation patterns are observed among different lesion types. That is, the data from both 129Xe ventilation functional MRI and CT provide complementary insights. The preliminary finding of this study offers data support for evaluating lung ventilation function caused by lung lesions, and provides more references for clinical imaging diagnosis, thereby contributing to the refinement of diagnostic and therapeutic strategies for pulmonary diseases.
