摘要：

Purpose. The aim of the present study was to evaluate the clinical significance of whole-body F-18 FDG PET in differentiated thyroid cancer and to compare the results with I-131 and T1-201 scintigraphy. Patients and Methods. Whole-body FDG-PET imaging was performed during the follow-up 31 patients (27-77 years old, F:M = 23:8, four with follicular cancer and 27 with papillary cancer) suffering from differentiated thyroid cancer after total thyroidectomy! An overall clinical evaluation was done including cytology, thyroglobulin level, sonography and computed tomography to allow a comparison with functional imaging results for each patient. Metastasis regions were divided into six areas: neck, lung, mediaternum, bone, others, unknown. Multiple lesions in one area were counted as one lesion. Results. There were 31 lesions in 29 patients. Compared with I-131 scintigraphy, FDG uptakes were concordant with I-131 uptakes only in 15 lesions. (36%) Compared with T1-201, FDG uptakes were concordant with T1-201 in 37 lesions (90%). Conclusion. For detecting metastatic lesions, FDG-PET and I-131 scintigraphy give complementary information whereas FDG-PET demonstrated similar Results to TI-201 scintigraphy. I-131 plus FDG-PET (or T1-201 scan) is a method of choice for detecting metastatic thyroid cancer after total thyroidectomy.
