Overview
The diagnostic and pre-therapeutic assessment of squamous cell carcinomas requires a neck and chest CT scan and a neck and facial MRI, which is the most effective examination, to establish the TNM stage of the tumor. However, obtaining this complete assessment can delay treatment. Confirmation of the non-inferiority of 40keV dual-energy CT in BOLT compared to MRI would spare the patient an additional MRI examination, speed up the pre-treatment assessment, reduce the loss of opportunity due to delayed treatment, and free up MRI imaging slots, which are still insufficient in the region.
Primary outcome measures
- Overall agreement established by interclass correlation on the T stage of TNM [Time frame: Up to 12 months]
Eligibility criteria
Inclusion criteria

- and a contrast-enhanced cervicofacial DECT with BOLT maneuver.
Exclusion criteria
- A lesion other than oral or oropharyngeal squamous cell carcinoma
- A labial location
- A contraindication to performing one or both of the imaging examinations.
