Screening period All patients will be during the screening screening assessment, specific include: the signing of the ICF, demographic data, drug allergy history and history, height, weight, physical examination, vital signs, electrocardiogram (ECG) examination, laboratory examination, blood pregnancy test records (if applicable), endoscopic biopsy, AE and drug combination, check into/standard. Qualified patients will enter the administration period after screening and confirmation. Administration period (from Administration to safety follow-up) day of administration (study day 1): before administration of the experimental drug, 12-lead ECG, laboratory test (fasting) and vital signs were measured. Subsequently, the experimental drug was injected intravenously at 0.3 ± 20% mCi/kg, and subjects underwent urination and SPECT/CT examination 40 min after administration. AE and combined medication were recorded. The next day after administration (day 2 of the study): 12-lead ECG, laboratory examination (fasting), vital signs were measured, AE and combined medication were recorded. Between the administration of 99mTc-3PRGD2 and the safety follow-up, the investigator determined that chest/abdomen enhanced CT and PET/CT were performed at an optional date. Safety follow-up (day 14±2 of the study or before the next clinical intervention, whichever is shorter) : 12 lead ECG, laboratory test (fasting), measurement of vital signs, blood pregnancy (women of childbearing age only), AE and combined medication were recorded.Lymph node histopathology was obtained by surgery in patients suitable for surgery, and by ultrasound-guided lymph node biopsy in patients unsuitable for surgery.
