摘要

68ga -前列腺特异性膜抗原（PSMA）主要通过泌尿系统排泄，但也部分通过胆道系统排泄。在此，我们提出这样一个病例，在一个男人与前列腺癌。68Ga-PSMA PET/CT显示骨转移灶中68Ga-PSMA摄取增加。肝总管、胆总管内68Ga-PSMA摄取增加，延迟显像时自行消退。

Pitfall in 68 Ga-PSMA PET/CT Interpretation : 68 Ga-PSMA Excreted Through the Biliary System.

68 Ga-Prostate-Specific Membrane Antigen (PSMA) is excreted mainly through the urinary system, but also partly through biliary system. Herein, we present such a case in a man with prostate cancer. The 68 Ga-PSMA PET/CT revealed increased uptake of 68 Ga-PSMA in bone metastases. Besides, increased 68 Ga-PSMA uptake in the common hepatic duct and common bile duct was observed, which resolved spontaneously in the delayed imaging.
