68Ga-FAPI PET/CT for the Detection of Adenoid Cystic Carcinoma(ACC)

Peking Union Medical College Hospital

This study was used to study the diagnostic value of 68Ga-FAPI, a novel fibroblast activating inhibitor, in metastatic adenoid cystic carcinoma（ACC）

68Ga-FAPI is a positron labeled inhibitor of fibroblast activating protein, which has been widely used in malignant tumor imaging in recent years. Adenoid cystic carcinoma (ACC) is a rare epithelial malignant tumor, which usually originates from salivary glands. Its typical characteristics are long clinical course and high rate of distant metastasis. The purpose of this study was to investigate the clinical value of 68Ga Fapi pet/ct in metastatic adenoid cystic carcinoma.

Inclusion Criteria:

• patients with ACC suspected metastatic tumor,and being able to provide basic information and sign the written informed consent form

Exclusion Criteria:

• claustrophobia, pregnancy, breastfeeding, kidney or liver failure, inability to fulfill the study
