Study of Melanoma-Resistant PET Monitoring Based on Key Rate-limiting Enzymes for Fatty Acid Metabolism in Healthy Volunteers

Recruit 15 healthy adult volunteers, divided into three groups, to undergo dynamic PET/CT (1 hour) and static PET/CT (2 hours and 3 hours) imaging with 68Ga-ACC-DE, 68Ga-FASN-DE, or 68Ga-ACLY-DE, respectively, to assess safety, biodistribution, and radiation dosimetry, laying the foundation for subsequent studies.
