Dual-time-point 18F-FDG PET imaging for diagnosis of disease type and disease activity in patients with idiopathic interstitial pneumonia.
Individual clinical courses of idiopathic interstitial pneumonia (IIP) are variable and difficult to predict because the pathology and disease activity are contingent, and chest computed tomography (CT) provides little information about disease activity. In this study, we applied dual-time-point [(18)F]-fluoro-2-deoxy-D-glucose ((18)F-FDG) positron emission tomography (PET), commonly used for diagnosis of malignant tumours, to the differential diagnosis and prediction of disease progression in IIP patients. ⋯ Early SUV and RI-SUV obtained from dual-time-point (18)F-FDG PET are useful parameters for the differential diagnosis and prediction of disease progression in patients with IIP.
