Early detection recurrent has become more important, as options disease have improved significantly. Objective: to evaluate role PET/CT postoperative evaluation suspected or metastases patients comparison with CECT. Methods: Between December 2018 2019, twenty histopathologically proven colorectal primary malignancy were evaluated local metastasis. No age predilection both sexes included, medical, clinical history, any other follow up images, tumor markers (CEA), pathological reports reviewed gold standard. Results: Local detected 10 by 90% sensitivity, specificity, accuracy, PPV NPV 9 CECT sensitivity 72.7%, specificity 88.8%, accuracy 80.0%, PPV88.8% 72.7%.
