Comparison of 18F-FDG and 68Ga-FAPI PET/CT in the diagnosis of lung metastasis in different malignant tumors
Background and purpose: 18F-flurodeoxyglucose (18F-FDG) positron emission tomography and computed tomography (PET/CT) is a common method for the diagnosis of malignant tumors with distant metastases.However the detection of lung metastases, especially small lesions, is still unsatisfactory.68Ga-labeled fibroblast activation protein inhibitors (68Ga
