18F-FDG PET/CT诊断胆管细胞癌的应用价值

目的 探讨¹⁸F-FDG PET/CT诊断胆管细胞癌的应用价值。方法 收集2017年9月—2020年10月山东省第一医科大学附属肿瘤医院行PET/CT检查的44例胆管细胞癌患者的病例资料，所有患者均行上腹部CT、MRI及全身PET/CT检查。比较3种检查对胆管细胞癌原发灶、复发灶、区域淋巴结的诊断价值。结果 CT、MRI、PET/CT 3种检查对胆管细胞癌原发灶、区域淋巴结转移的诊断敏感性差异无统计学意义（P > 0.05）；3种检查对胆管细胞癌复发灶的诊断敏感性差异有统计学意义（P < 0.05）。结论 PET/CT检查在胆管细胞癌复发灶的诊断方面具有较高的诊断价值，而3种检查方法在胆管细胞癌原发灶、区域淋巴结转移方面的诊断敏感性差异无统计学意义。

Application value of 18F-FDG PET/CT in the diagnosis of cholangiocarcinoma

Objective To explore the value of ¹⁸F-FDG PET/CT in the diagnosis of cholangiocarcinoma. Methods Data were collected from 44 patients with cholangiocarcinoma who underwent PET/CT in Affiliated Cancer Hospital of Shandong First Medical University from September 2017 to October 2020. All patients underwent upper abdominal CT and MRI and whole-body PET/CT. The diagnostic value of three examinations was compared for primary lesions, recurrent lesions, and regional lymph node metastasis of cholangiocarcinoma. Results There were no significant differences in the diagnostic sensitivity of CT, MRI, and PET/CT in the primary lesions and regional lymph node metastasis of cholangiocarcinoma (P > 0.05). There were significant differences in the diagnostic sensitivity of the three examinations for recurrent cholangiocarcinoma lesions (P < 0.05). Conclusion PET/CT has high diagnostic value for recurrent lesions of cholangiocarcinoma, but the three examinations showed no significant differences in the diagnostic sensitivity for primary lesions and regional lymph node metastasis.
