Overview

On conventional radiography, characteristic findings of solitary pulmonary nodule, include: well-defined, small, rounded capacities within the pulmonary interstitium, usually 8 mm in diameter, normally surrounded by normal aerated lung.

Chest X Ray

  • Conventional chest radiograph may be helpful in the diagnosis of pulmonary nodules.
  • The majority of pulmonary nodules require further evaluation with CT scan and MRI
  • On conventional radiography, characteristic findings of pulmonary nodule, include:[1]
  • Soft-tissue density mass
  • Round or oval in shape
  • Smooth margin
  • Diameter of 8 mm and irregular margins
  • Surrounded by areas of ground glass change
