Arm && Interventions

Group	Intervention	Description
68Ga-NOTA-MAL-NB147	18F-FDG	All enrolled participants will be allocated to this arm (single-arm study). Study participants will undergo 68Ga-NOTA-MAL-NB147 PET/CT scan.

Primary Outcome Measures

Name	Time	Method
Standardized uptake value（SUV）	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-NOTA-MAL-NB147） in solid tumor lesions by measuring SUV on PET/CT.
