18F-FAPI PET in Lung Cancer

1. Patients clinically suspected or confirmed with lung cancer are required to complete conventional imaging examinations (CT/MR or FDG PET) and undergo ¹⁸F-FAPI PET/CT. 2. Conduct a detailed inquiry into the patient's medical history to clarify symptoms, signs, and prior medical history (e.g., tumor history, surgical history, biopsy history, radiotherapy history, chemotherapy history, family history, allergy history, etc.), as well as relevant laboratory tests and previous imaging findings (including plain radiography, ultrasound, CT, MRI, 18F-FDG PET/CT, PET/MR, etc.). 3. For follow-up coordination, you are required to regularly provide your clinical data (e.g., treatment plans, disease progression, etc.) as per the study requirements. This collaboration is essential for completing long-term follow-up, including monitoring the subject's condition, imaging findings, pathological results (such as tumor grading and Ki-67 index), and patient treatment outcomes, to collect prognostic information. 4. ¹⁸F-FAPI PET/CT and conventional imaging examinations (e.g., CT/MR) were completed prior to enrollment. After enrollment in this study, subjects were not required to undergo additional imaging or laboratory tests, only requiring follow-up without intervention to the clinical treatment plan.
