An observational study in Using Functional Lung MRI to Explore Pulmonary Perfusion Changes in Patients With Pulmonary Fibrosis and Emphysema Syndrome, sponsored by Beijing Chao Yang Hospital. Recruiting at 1 site in China. Per ClinicalTrials.gov, last updated 2024-05-28.
Sponsored by Beijing Chao Yang Hospital · Observational
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.
382 studies on the registry are indexed under Emphysema; 59 are open to participants now.
This study's planned enrollment of 55 is below the median of 131 across 111 observational studies indexed under Emphysema.

(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:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
