摘要
目的 :评价术前应用正电子发射型断层扫描 (PET)、CT对胃癌的诊断价值。方法 :2 8例胃癌患者术前行PET全身显像 ,2 3例行CT检查 ,将以上结果和病理分期对照。结果 :PET和CT对胃癌局部病灶的显示率分别为 92 .9%和 82 .6 % ,PET对淋巴结的检测准确性 (87.5 % )高于CT(6 1.9% )。PET检测出 8例远处转移患者 ,CT漏诊 3例。结论 :PET相对于CT能更准确检测原发和复发胃癌淋巴结及远处转移灶 ,对胃癌的临床诊断有较高的应用价值。
Objective:A study was performed to evaluate the diagnostic value for positron emission tomography (PET) using fluorodeoxyglucose (FDG) in patients with primary or recurrent gastric cancer correlated with computed-tomography. Methods:28 patients were included in the study. All patients had a PET scan. Preoperative staging of gastric cancer with CT were performed in 23 patients. These results were compared with the histopathological staging to evaluate the accuracy and usefulness of PET preoperation staging of patients with gastric cancer.Results:The accuracy in detecting primary tumor (T) by PET and CT was 92.9% and 82.6% respectively. For N the PET scan was accurate in 87.5% compared with CT in 61.9%. PET identified 8/8 patients with distant metastases and CT 4/7. Conclusion:PET scanning is a sensitive method for detecting lymph node and metastatic leision in patients with primary or recurrent gastric carcinoma compared with CT. PET appeared to be better in assessing recurrent tumour than CT.
