    Eligibility Criteria

    Criteria

    Ages Eligible for Study:
    19 Years and Older
    Sexes Eligible for Study:
    All
    Accepts Healthy Volunteers:
    No
    Inclusion Criteria:
    In order to be eligible for participation in this trial, the subject must:
    • Be ≥ 19 years of age.

    • Patients diagnosed with central nervous system lymphoma by surgery/biopsy or suspected of central nervous system lymphoma by anatomical imaging examination such as MRI.

    • Patients who have results or are planning to examine 18F-FDG PET in the above patients.

    Exclusion Criteria:

    The subject must be excluded from participating in the trial if the subject fulfil any single criteria described below:

    • Pediatric and adolescent patients under 19 years of age.

    • The patient is pregnant, is attempting to become pregnant, or is nursing (breast-feeding) to children.

    • Patients with diagnosed or suspected lymphoma lesions in organs other than the cetral nervous system.

    • Based on the investigator's judgement, if the patient makes it impossible to collect complete data for a clinical trial due to personal or other reasons.

    • Patients who cannot stably have PET/CT due to claustrophobia, dyskinesia, anxiety disorder, seizure, etc.

    • Based on the investigator's judgement, if the patient has a serious and/or uncontrolled and/or unstable medical disease (e.g., congestive heart failure, acute myocardial infarction, severe lung disease, chronic renal disease or chronic liver disease, etc.)
