Summary of Patients with Interstitial Lung Disease Who Underwent In Vivo Endobronchial Optical Coherence Tomography

Case No.	Age/Sex	HRCT Interpretation	In Vivo Endobronchial OCT Diagnosis	Surgical Lung Biopsy Diagnosis
1	56/M	Nondiagnostic	UIP	UIP
2	74/M	Nondiagnostic	UIP	UIP
3	69/M	Nondiagnostic	UIP	UIP
4	52/F	UIP	Non-UIP/IPF ILD	Non-UIP/IPF ILD
5	64/M	Nondiagnostic	UIP	Indeterminate*

Definition of abbreviations: HRCT = high-resolution computed tomography; ILD = interstitial lung disease; IPF = idiopathic pulmonary fibrosis; OCT = optical coherence tomography; UIP = usual interstitial pneumonitis.

^*Reviewed by five pathologists: interpreted by three as UIP without clear honeycomb; by one as indeterminate, UIP possible; and by one as chronic organizing pneumonia.
