To investigate the biological distribution of a new tracer 68Ga-FAPI-JNU in the primary, metastatic and normal tissues of patients with malignant tumors, and to evaluate the biological distribution of 68GA-FAPI-JNU with standardized uptake values.

PET/CT imaging was performed about 1 hour after the patient was injected with the novel tracer 68Ga-FAPI-JNU. SUVmax and SUVmean values of the area of interest were mapped by two diagnostic physicians with more than 5 years of experience after the imaging was completed.
