FDG-PET scan may be helpful in the diagnosis of pneumoconiosis. Findings on an FDG-PET scan can help differentiate between benign and malignant lesions. [1]

Other Imaging Findings

FDG-PET scan (Fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) scans) may be helpful in the diagnosis of pneumoconiosis. Findings on an FDG-PET scan suggestive of/diagnostic of pneumoconiosis include helping to differentiate between progressive massive fibrosis in pneumoconiosis and lung cancer. [2] However, there is a high rate of false positives and CT scan is a better option. [3] [4] [5]
