Exploring the Application Value of PET Molecular Imaging Targeting FAP in Oral Squamous Cell Carcinoma
In this prospective study, the investigators will use integrated PET/CT with the agent 68Ga-FAPI and conventional imaging agent 18F-FDG to explore the application value of FAP-targeted molecular imaging in the diagnosis and staging for oral cancer. This study also aims to explore the application value of FAPI imaging in evaluating treatment response for oral cancer.
• Voluntary participation with signed informed consent;
• Aged 18\
⁃ 70 years;
• Clinically highly suspected oral cancer and recurrence after treatment (Newly diagnosed patients: Scheduled for surgery or neoadjuvant therapy followed by surgery);
• Ability to complete baseline and follow-up PET/CT (Follow-up FAPI PET/CT applies only to locally advanced patients undergoing neoadjuvant therapy.).
