NCT05442151

Brief Summary

PET / CT examination using \[18F\] FAPI-74 is performed on patients diagnosed with malignant tumor, and the pathological condition is determined by comparing with FDG-PET/CT examination of conventional diagnostic imaging.

Outcome Measures

Primary Outcomes (3)

  • Comparison of the uptake on FAPI-PET with conventional imaging

    Comparison of SUV (standardized uptake value) of primary site and metastatic lesions between FAPI-PET and FDG-PET

    Within 2 hours after administration of [F-18]FAPI-74 injection

  • Comparison with pathological specimens

    Comparison of expression level (staining score) in FAP immunostaining and SUV in FAPI-PET (FAP staining is graded by scoring evaluation: high expression (3 points), moderate expression (2 points), mild expression (1 point), and no significant expression (0 point).)

    Within one month after FAPI-PET

  • Time course of uptake on FAPI-PET

    Time course of uptake on FAPI-PET before and after treatment compared with conventional imaging

    Approximately 6 months after initial FAPI-PET
