Purpose: The study aimed to investigate the imaging parameters of 18F-fluorodeoxyglucose (18F-FDG) PET/computed tomography (PET/CT) in nasopharyngeal carcinoma (NPC), specifically examining the relationship between mean standardized uptake value (SUVmean), maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) with Ki-67 expression, T-stage, and tumor node metastasis (TNM) stage.
Methods: A retrospective analysis was conducted on 143 consecutive NPC patients from January 2015 to December 2023 who underwent 18F-FDG PET/CT for initial disease assessment. SUVmax, SUVmean, MTV, and TLG were quantified from PET/CT images.
Background: Nasopharyngeal carcinoma (NPC) originates in the nasopharyngeal mucosa, the lateral wall of the nasopharynx. A significant challenge in NPC management is skull-base bone invasion (SBBI), which affects prognosis and treatment planning. Magnetic resonance imaging (MRI) is the primary diagnostic tool for SBBI in NPC patients; however, the detection of SBBI can be challenging due to skull-base complexity and overlapping MRI signals.

F-sodium fluoride (F-NaF) positron emission tomography-computed tomography (PET/CT) offers potential advantages in detecting early bone involvement. This retrospective cohort study aimed to assess the potential advantage of F-NaF PET/CT for clinical staging and management planning in patients with NPC and to compare F-NaF PET/CT findings with those of conventional imaging modalities.

The sensitivity, specificity, and accuracy were calculated.

Methods: Our study retrospectively analyzed 58 patients with pathologically proven NPC. They all underwent both F-NaF PET/CT and planar Tc-MDP bone scintigraphy within a 7-day interval.
