Summary
This is a prospective, single-center, diagnostic study designed to compare the accuracy of \[68Ga\]Ga-CTR-FAPI PET/MRI and \[18\]F-FDG PET/MRI for the detection of lymph node metastasis in patients with initially untreated, resectable middle to high rectal cancer. The study aims to evaluate whether \[68Ga\]Ga-CTR-FAPI PET/MRI provides higher sensitivity and specificity than traditional 18F-FDG PET/MRI at both the patient level and the lymph node level.
