This review highlights imaging modalities for detecting recurrence in head and neck cancer, suggesting optimal surveillance strategies.

To evaluate the effectiveness of different imaging modalities in detecting residual or recurrent head and neck squamous cell carcinoma.
Reviewed current imaging modalities for post-treatment surveillance
Evaluated contrast-enhanced computed tomography and its role
Assessed the utility of magnetic resonance imaging for skull base tumors
Discussed the effectiveness of diffusion-weighted imaging
Analyzed the role of 18F-fluorodeoxyglucose PET/CT in surveillance.
Contrast-enhanced CT is the primary imaging modality for tracking locoregional recurrence.
Magnetic resonance imaging excels in diagnosing skull base tumors and bone invasion.
Diffusion-weighted imaging effectively distinguishes residual tumors from treatment effects.
FDG-PET/CT shows higher sensitivity compared to CT and MR imaging for residual or recurrent tumors.

Kashiwagi et al. (2026) studied this question.
