摘要
目的探讨PET/CT显像在胃癌术前诊断中的临床应用价值。方法18例术前考虑为胃癌的患者行PET/CT全身显像,并将结果与术后病理对照。结果PET/CT考虑为胃癌18例,术后病理结果均为胃癌。PET/CT诊断胃癌准确度100%,灵敏度100%。淋巴结转移灶的准确率为78.4%,淋巴结外远处转移灶的准确率为100%;灵敏度为93.2%,特异性为28.5%。结论PET/CT对胃癌原发灶及远处转移灶的诊断有较高的临床价值,对手术有较大的指导作用。
Objectives To evaluate the value of 18F - FDG PET/CT（fluorodeoxyglucose position emission tomography）in diagnosing gastric carcinoma and its metastasis before operation. Methods Taking ^18SF-FDC PET/CT on 18 suspicions of gastric carcinoma. The results of PET/CT dignosis and the pathology diagnosis after operation were compared. Results 18 diagnosed patients were concluded to suffer from gastric carcinoma by PET/CT,and 18 patients were diagnosed as gastric careinoma after operation by pathology diagnosis. The accuracy of the diagnoses of gastric carcinoma by PET/CT was 100% ,the sensitivity was 100% . As to the metastatic of lymph node the accuracy was 78.4% ,metastatic locations the accuracy was 80.8% ,sensitivity was 93.2% ,specificity was 28.5%. Conclusion PET/CT diagnosis has high clinical value in primary gastric carcinoma and metastasis lesions ,and also helpful for guiding the surgery.
