Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study intends to use magnetic resonance pulmonary function imaging technology to explore imaging markers for early diagnosis of patients with CPFE. Through baseline, 6-month and 12-month follow-up examinations, the changes in magnetic resonance pulmonary function in patients with CPFE and their correlation with disease progression were explored.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* (1) Chest HRCT shows emphysema mainly distributed in the upper lung field, manifesting as wallless or thin-walled (wall thickness \<1 mm) low-transmittance areas with clear boundaries with normal tissue, or multiple bullae (diameter \> 1 cm), and the emphysema area/total lung volume is ≥10%; (2) interstitial pulmonary fibrosis mainly distributed in the lower lung field and subpleura, manifesting as honeycomb shadow or grid shadow, and the lung structure is destroyed , may be accompanied by traction bronchiectasis, ground glass opacities and consolidation opacities.

Exclusion Criteria

* (1) Refusal to sign the informed consent form; (2) MRI contraindications (implanted pacemaker/defibrillator, claustrophobia, or any clinical condition that prohibits longer MRI examinations).
