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
