Overview
This article describes a method for imaging ex vivo pulmonary resection specimens using optical frequency domain imaging (OFDI) and correlating these images with histology. This technique is crucial for developing specific OFDI interpretation criteria for pulmonary pathology and can be applied to various tissue types.
Key Study Components

What is OFDI?
Optical Frequency Domain Imaging (OFDI) is an imaging technique used to obtain detailed images of tissue structures.
How does OFDI correlate with histology?
OFDI images are correlated with histology by marking specific points on the tissue to ensure accurate matching of features.
What type of specimens were used in this study?
Swine lung specimens were used for ex vivo imaging and histological correlation.
What are the advantages of using OFDI?
OFDI allows for high-resolution imaging and direct correlation with histological features, enhancing diagnostic accuracy.
Can this method be applied to other tissues?
Yes, the technique can be adapted for various tissue types beyond pulmonary specimens.
What is the significance of this research?
This research aims to improve the interpretation of imaging in pulmonary pathology, which can lead to better diagnostic practices.
