Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The goal of this observational study is to learn about the diagnostic effectiveness, safety, and influencing factors of transbronchial cryobiopsy（TBLC） in progressive pulmonary fibrosis. The main question it aims to answer are: • The diagnostic rate of MDD1 or MDD2 based on TBLC. • The rate of hemorrhage, pneumothorax, acute ILD exacerbation and mortality. Participants' medical records will be collected by us.
