Overview

HRCT scan have a high specificity in the diagnosis of pneumoconiosis. It is particularly helpful to detect pleural findings. [1][2]

CT scan

HRCT scan may be helpful in the diagnosis of pneumoconiosis. Findings on CT scan suggestive of/diagnostic of pneumoconiosis include:

  • Silicosis: [3] [4] [5]
    • Small rounded opacities
    • Hyalinized nodules in the upper lobes
    • Emphysema
    • Ground glass opacities
    • Interlobular thickening
  • Asbestosis: [6] [7] [8]
    • Pleural effusions
    • Pleural thickening
    • Fibrosis
    • Honeycombing
    • Pleural plaques
  • Berylliosis: [9] [10]
    • HRCT can be normal in positive cases in 25% of patients.
    • Parenchymal nodules
    • Ground glass opacities
    • Bronchial wall thickened
    • Adenopathy
    • Septal lines thickened
  • Coal Worker's Pneumoconiosis: [10]
    • Honeycombing
    • Reticular opacities
  • Hard Metal Pneumoconiosis: [11]
    • Ground glass opacities
    • Reticular opacities
