Arm Intervention/treatment
Experimental: 68Ga-ACN376
Imaging cohort All study participants will be allocated to this arm (single-arm study). Study participants will undergo 68Ga-ACN376 PET/CT scan.
Drug: 18F-FDG
All study participants will undergo one 18F-FDG PET/CT scan.

Primary Outcome Measures :
  1. Standardized uptake value(SUV) [ Time Frame: 2 years ]
    SUV is a semi-quantitative analysis index to describe the radioactive uptake of lesions, which has certain reference value for differentiating benign and malignant lesions。 The uptake of the tracer (68Ga-ACN376) in solid tumor lesions by measuring SUV on PET/CT.
