Abstract：Objective To investigate the diagnostic value of 18F-FDG PET/CT in malignant lesions of the pharynx region by analyzing the PET/CT imaging data of space-occupying lesions. Methods The imaging data of 44 patients who had 18F-FDG PET/CT examination in our hospital from January 2016 to July 2019 for diagnosis or suspicion of malignant lesions in the pharyngeal isthmus region were collected. The sensitivity, specificity and accuracy of 18F-FDG PET/CT for local lesions and lymph node metastasis of malignant lesions in the pharyngeal isthmus region were analyzed by comparison with the final pathology and follow-up results. Results There were 44 cases with positive PET/CT imaging of local lesions in the pharyngeal isthmus area, including 42 cases with malignant lesions and 2 cases with benign lesions. The sensitivity, specificity and accuracy of 18F-FDG PET/CT in the diagnosis of malignant lesions in the pharynx region were 100%, 50% and 97.7%, respectively. 30 cases had positive PET/CT imaging of lymph nodes, 28 cases were finally confirmed as lymph node metastasis by pathology or follow-up, 2 cases had inflammatory hyperplasia of lymph nodes. The sensitivity, specificity and accuracy of 18F-FDG PET/CT in the diagnosis of lymph node metastasis were 96.5%, 86.7% and 93.1% (41/44). 18F-FDG PET/CT could accurately show the location, scope and lymph node metastasis of the recurrent lesions in 6 of the 42 malignant lesions. Conclusion 18F-FDG PET/CT is of great value in the diagnosis of malignant tumors in the pharyngeal isthmus region, lymph node metastasis and postoperative recurrence.
