PURPOSE The purpose of this exhibit is: 1. To review the major types of pulmonary function tests (PFTs) including spirometry (FEV1, FVC), measurements of lung volumes (TLC), and quantification of diffusion capacity (DLCO). 2. To review the interpretation of pulmonary function test values in determining the pattern of abnormality (i.e. obstructive, restrictive, or mixed). 3. To correlate abnormal pulmonary function test patterns with chest x-ray and/or chest CT imaging findings. TEACHING POINTS The major teaching points are: 1. To review the basic principles of lung physiology and the major types of pulmonary function testing. 2. To provide the radiologist with an organized approach to interpreting PFTs and identify patterns of lung disease. 3. To correlate abnormal pulmonary function test patterns with chest imaging findings. 4. To guide the radiologist in forming and narrowing differential diagnoses based on the combination of imaging findings and PFT values.

CONTENT ORGANIZATION Briefly review lung physiology associated with PFT measurements. Describe abnormal PFT results and their clinical significance. Provide a simple algorithm in identifying the main patterns of lung disease based on PFT values. Review chest x-ray and chest CT imaging findings that correlate with specific abnormal PFT patterns.
