1. Visual analysis of images: describe the location, size, shape and degree of uptake of lesions;
2. Semi-quantitative analysis: the ratio of lesion site uptake to liver uptake was measured by area of interest method (ROI);
3. Comparative analysis: Compared with clinical routine 18F-FDG PET/CT imaging, the advantages of PSMA PET/CT imaging were clarified;
4. Evaluation and analysis of efficacy: before and after treatment, to clarify the early treatment evaluation value of PSMA PET/CT imaging, and compare it with 18F-FDG PET/CT imaging;
5. Prognostic study: Through multi-factor analysis, the relationship between the level of PSMA PET/CT imaging uptake and the prognosis of patients was clarified.
