Dual-energy CT vs. MRI in the Evaluation of Squamous Cell Carcinomas of the Oral Cavity and Oropharynx

This study is comparing two types of detailed imaging — dual-energy CT (DECT) and MRI — to see which is better at assessing the extent of squamous cell cancers of the mouth and throat (oral cavity and oropharynx) before surgery. Better imaging could help surgeons plan more precise operations. **You may be eligible if...** - You are 18 or older - You have a confirmed squamous cell carcinoma of the mouth or throat (oral cavity or oropharynx) - You have already had an ENT specialist examination and received both a contrast-enhanced MRI and a dual-energy CT scan as part of your staging workup **You may NOT be eligible if...** - Your cancer is a different type (not squamous cell) - Your tumour is on the lips - You cannot have one or both of the imaging scans (e.g., MRI contraindication) Talk to your doctor to see if this trial is right for you.
