Magnetic Resonance Lung Function Imaging Study of Pulmonary Fibrosis Combined With Emphysema Syndrome

May 22, 2024 updated by: Beijing Chao Yang Hospital
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.

Study Population

(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.
