[18F-FDG PET in the diagnosis of head and neck tumor].
OBJECTIVE
To analyze the value of 18F-FDG PET in the diagnosis of patients suspected of having head and neck malignant tumor.


METHODS
Seventy-five cases patients suspected of having head and neck cancer or recurrence were analyzed retrospectively. 18F-FDG PET was performed in all cases. The results of some cases were compared with CT and MRI.


RESULTS
18F-FDG PET yielded a sensitivity 91.30% and specificity 76.92% and accuracy 86.11% in the diagnosis of nasopharyngeal carcinoma; sensitivity 100.00% and specificity 83.33% and accuracy 94.44% in esophageal carcinoma; sensitivity and specificity and accuracy 100% in thyroid carcinoma, laryngeal carcinoma and hypopharyngeal carcinoma.


CONCLUSIONS
Preliminary clinical application of 18F-FDG PET has demonstrated its significant advantages in evaluating head and neck malignant diseases.
