摘要: 18 F-fluorodeoxyglucose positron emission tomography (FDG-PET) imaging is highly accurate in restaging colorectal cancer, esophageal and gastrointestinal stromal tumors. Overall, it compares favorably with anatomical the evaluation of tumor recurrence because metabolic abnormalities usually precede a structural change. Initial staging these malignancies PET best used patients locally advanced disease who may benefit from curative resection if distant metastases are not found. It also appears to have great potential predicting histopathologic response neoadjuvant therapy monitoring success radiofrequency ablation 90 Y microspheres radioembolization soon after intervention. FDG-PET can be other as prognostic tool detect but its role has yet been well defined.
