Eligibility Criteria
1. adult patients (aged 18 years or order); 2. patients with suspected or newly diagnosed or previously treated malignant tumors (supporting evidence may include MRI, CT, tumor markers and pathology report); 3. patients who had scheduled AATS PET/CT scan; 4. patients who were able to provide informed consent (signed by participant, parent or legal representative) and assent according to the guidelines of the Clinical Research Ethics Committee.
You may qualify if:
- adult patients (aged 18 years or order);
- patients with suspected or newly diagnosed or previously treated malignant tumors (supporting evidence may include MRI, CT, tumor markers and pathology report);
- patients who had scheduled AATS PET/CT scan;
- patients who were able to provide informed consent (signed by participant, parent or legal representative) and assent according to the guidelines of the Clinical Research Ethics Committee.
You may not qualify if:
- patients with non-malignant lesions;
- patients with pregnancy;
- the inability or unwillingness of the research participant, parent or legal representative to provide written informed consent.
