To evaluate the normal physiological distribution of positron nuclide labeled NOTA-F API in human body and its detection efficiency for lymphoma

Subjects first undergo an 18F-FDG test, followed by 68Ga-NOTA-FAPI04 or 18F-NOTA-FAPI04 test in groups.Investigate the standardized uptake value(SUV) of 68Ga/ 18F-NOTA-FAPI04 for the target lesion, the ratio of the standardized uptake value(SUVR) of 68Ga/ 18F-NOTA-FAPI04 for the target lesion within each time window to that of the normal corresponding tissue.

Inclusion Criteria:

• ECOG score 0 or 1
• subjects with lymphoma or suspected tumor subjects who have recently (within 2 months) planned to receive pathological biopsy or tumor surgery
• expected survival ≥12 weeks
