Overview
CT scan
- Computed tomography may be helpful in early diagnosis of interstitial lung disease.[1]
- In MCTD, the tomographic images may show radiographic abnormalities related to interstitial lung disease and the presence of esophageal dilatation:
- Areas of increased attenuation in which the bronchi and vessels remain visible (ground glass opacities)
- Irregularity of the interfaces between the peripheral pleura and aerated lung parenchyma or small lines perpendicular to the pleura (Interface sign)
- Septal and nonseptal lines (linear opacities)
- Bronchiolectasis or traction bronchiectasis: dilatation of the airways in the peripheral portion of the lungs
- Areas of cystic spaces (diameter <1 cm) with thickened walls (honeycombing)
- Areas of decreased attenuation and air trapping on expiratory computed tomography
- Esophageal dilatation (esophagus may be fluid filled or has an air-fluid level)
