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.
