Clinical Application of FL-091 Radionuclide Imaging in Diagnosis and Staging of Malignant Tumors

This study is diagnostic. Oncologists screen patients with malignant tumors such as head and neck cancer, colorectal cancer, and pancreatic adenocarcinoma who are clinically suspected or confirmed; investigators talk to patients who meet the inclusion criteria, explain the study purpose and study process, sign informed consent forms, and patients can complete 68Ga-FL-091PET imaging and 111In-FL-091SPECT imaging respectively in outpatient or inpatient periods. General information, clinical data, blood routine, urine routine, liver and kidney function and other biochemical indicators, electrocardiogram, radionuclide imaging results and other imaging data of the patients participating in the study were collected and compared with histopathology to evaluate the value of both imaging in the diagnosis of head and neck cancer, colorectal cancer, and pancreatic adenocarcinoma.
