Paraseptal emphysema: Prevalence and distribution on CT and association with interstitial lung abnormalities.

ABSTRACT:

Objective

To investigate the prevalence and distribution of paraseptal emphysema on chest CT images in the Framingham Heart Study (FHS) population, and assess its impact on pulmonary function. Also pursued was the association with interstitial lung abnormalities.

Materials and methods

We assessed 2633 participants in the FHS for paraseptal emphysema on chest CT. Characteristics of the participants, including age, sex, smoking status, clinical symptoms, and results of pulmonary function tests, were compared between those with and without paraseptal emphysema. The association between paraseptal emphysema and interstitial lung abnormalities was investigated.

Results

Of the 2633 participants, 86 (3%) had pure paraseptal emphysema (defined as paraseptal emphysema with no o
