【 要旨 】 | 胆道癌の診断において,FDG-PET (fluorodeoxyglucose-positron emission tomograhphy) は手術適応の決定,リンパ節の診断に有用だが,現在保険適応はない.拡張胆管の診断などではMRIが有用である.膵癌の診断では,FDG-PETは良悪性鑑別のみならず,病期診断,転移/再発診断でも有用である.膵癌での局所浸潤や血管浸潤はMD-CT診断が必須で,微小肝転移の診断ではCT,MRIの併用が望ましい.今後はPET / CTや融合画像などの総合画像診断が期待されている. |

[ Summary ] | PET is a valuable imaging tool in the diagnosis of bile duct cancer in relation to staging, evaluation of LN metastasis and operability. However, there is no coverage by healthcare insurance in Japan, so far. FDG-PET is useful in the diagnosis of pancreatic cancer for differential diagnosis, staging, and detection of metastasis and recurrence. However, additional information from MD-CT and MRI would be better in the evaluation of local invasion and detection of small liver metastasis. Multi-modality imaging with MD-CT or MRI (such as PET / CT or fusion imaging) is expected to increase in the future. |
