Abstract: Objective Evaluate the diagnostic value of PET/CT in the preoperative advanced gastric carcinoma comparing with mult;-slice spiral computed tomography. Methods Thirty-nine advanced gastric carcinoma patients taking PET/CT and abstract 40 advanced gastric carcinoma patients performing MSCT before operation,were done the TNM staging, and the Results were compared with the operation histopathology. Results For diagnosing primary lesions, regional lymph nodes, N3 lymph nodes ,PET/CT was accurate in 92.3% , 66.7% and 100.0%.Instead, MSCT was accurate in 82.0% , 50.0% and 62.5%. Conclusions (1) PET/CT and MSCT have high accuracy in diagnosing primary lesions and regional lymph nodes. But for detecting the N3 lymph nodes and distant metastasis, PET/CT has higher accuracy than MSCT. PET/CT combining abdominoscopy may decrease or avoid exploratory laparotomy.
