The combination of positron emission tomography (PET) with computed tomography (PET-CT) provides simultaneous metabolic and anatomic information on tumors in the same imaging session. Sensitivity of PET/PET-CT is higher for intrahepatic (>90%) than for extrahepatic cholangiocarcinoma (CCA) (about 60%). The detection rate of distant metastasis is 100%. PET, and particularly PET-CT, improves the results and impacts on the oncological management in CCA compared with other imaging modalities. Therefore, PET-CT is recommended in the preoperative staging of intrahepatic (strength of recommendation: moderate) and extrahepatic (strength of recommendation: low) CCA.
正电子发射断层扫描(PET)与计算机断层扫描(PET-CT)相结合,可在同一次成像过程中同时提供肿瘤的代谢和解剖信息。PET/PET-CT 对肝内(>90%)比肝外胆管癌(CCA)(约 60%)的敏感性更高。远处转移的检出率为 100%。与其他影像学方法相比,PET 尤其是 PET-CT,可改善 CCA 的结果并影响肿瘤治疗管理。因此,推荐在肝内(推荐强度:中度)和肝外(推荐强度:低度)CCA 的术前分期中使用 PET-CT。
