## Overview[edit | edit source]

High-resolution CT (HRCT) scan of the chest may be helpful in the diagnosis of scleroderma interstitial lung disease and pulmonary hypertension. Findings on HRCT suggestive of interstitial lung disease include architectural distortion due to pulmonary fibrosis, reticular interlobular interstitial thickening, increased ground glass opacity and accentuated reticular markings on juxtapleural, posterior and basilar portion of the lungs, traction bronchiectasis and honeycomb cystic change.

## CT scan[edit | edit source]

High-resolution CT (HRCT) scan of the chest may be helpful in the diagnosis of scleroderma interstitial lung disease and pulmonary hypertension. Findings on CT scan suggestive of interstitial lung disease include:[1][2][3][4]

* Architectural distortion due to pulmonary fibrosis
* Reticular interlobular interstitial thickening
* Increased ground glass opacity and accentuated reticular markings on juxtapleural, posterior and basilar portion of the lungs
* Traction bronchiectasis
* Honeycomb cystic change
