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.

RECRUITINGOverall agreement established by interclass correlation on the T stage of TNM
Overall agreement established by interclass correlation on the T stage of TNM between the radiological analysis of the DECT 40 kev BOLT, and of the MRI, compared to the reference T stage of TNM from the RCP: Overall agreement: This means: do the methods give the same results? We want to know if DECT and MRI reach the same T stage for the same patient. Example: DECT: T3 MRI: T3 Result: Good agreement DECT: T2 MRI: T3 Result: Disagreement
Time frame: Up to 12 months
