Brief Summary:

Primary objective To investigate the safety and tolerability profile of 68Ga- NODAGA-SNA006 in patients with solid tumors; To investigate the radiation absorbed dose characteristics of 68Ga-NODAGA-SNA006 in patients with solid tumors; To investigate the distribution profile of 68Ga-NODAGA-SNA006 in patients with solid tumors. Secondary objectives To investigate the optimal administration dose and radiation safety profile of 68Ga-NODAGA-SNA006; To investigate the PET imaging characteristics and high-quality imaging time window of 68Ga-NODAGA-SNA006 in patients with solid tumors; To explore the correlation between PET imaging characteristics of 68Ga-NODAGA-SNA006 binding to CD8 and histological CD8 expression characteristics; To explore peripheral blood T lymphocyte differentiation (CD8, CD4, CD3, etc.) in patients with solid tumors.
