Usefulness of 201TL SPECT/CT relative to 18F-FDG PET/CT in detecting recurrent skull base nasopharyngeal carcinoma.

BACKGROUND This study was designed to compare (201)Tl single photon emission computed tomography (SPECT)/CT with 18-fluoro-2-deoxyglucose ((18)F-FDG) PET/CT in diagnosing recurrent skull base nasopharyngeal carcinoma (NPC). METHODS Twenty-seven patients were recruited. Both (201)Tl SPECT/CT and (18)F-FDG PET/CT for each patient were performed at least 4… CONTINUE READING
