EVALUATION OF PRIMARY PULMONARY CARCINOID-TUMORS USING FDG PET

OBJECTIVE. The purpose of this study was to determine the spectrum of positron emission tomography (PET) with F-18-fluorodeoxyglucose (FDG) findings in patients who have primary pulmonary carcinoid tumors. CONC LUSION. On FDG PET imaging, pulmonary carcinoid tumors usually have lo wer FDG uptake than expected for malignant tumors. Biopsy or close rad iologic follow-up is therefore recommended for solitary pulmonary nodu les that are clinically suspected of being carcinoid tumors and that d o not show increased metabolic activity on FDG PET images.
