摘要: Purpose: To investigate the clinical benefits of F18-fluorodeoxyglucose-positron emission tomography and computed ( 18 F-FDG-PET/CT) over multi-detector row CT (MDCT) in preoperative staging gastric cancer. Methods: FDG-PET/CT MDCT were performed on 78 patients with cancer pathologically diagnosed by endoscopy. The accuracy radiologic retrospectively was compared to pathologic result after curative resection. Results: Primary tumors detected 51 (65.4%) F-FDG-PET/CT, 47 (60.3%) MDCT. Regarding detection lymph node metastasis, sensitivity 51.5% an 71.8%, whereas those 69.7% 69.2%, respectively. F-FDG-PET/CT for a primary tumor signet ring cell carcinoma lower than that non-signet (35.3% vs. 73.8%, P ＜ 0.01). Conclusion: Due its low sensitivity, alone shows no definite benefit prediction metastasis
