The study of dual-phase 18F-FDG PET/CT-based models in predicting malignant solitary pulmonary lesions
This research aimed to create a radiomics-based prediction model using dual-phase 18F-fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET/CT) for noninvasive classification of solitary pulmonary lesions. A total of 132 patients were included. The optimal CT+(PET2-PET₁)/PET₁ model achieved the highest AUC of 0.898, demonstrating promising diagnostic efficacy and can be a clinical diagnostic tool to distinguish between benign and malignant solitary pulmonary lesions. The study highlights the potential of dual-phase 18F-FDG PET/CT radiomics analysis to improve diagnostic accuracy and reduce unnecessary invasive examinations for lung cancer.
