This article explores the fundamental principles of Nuclear Medicine, highlighting its diagnostic and therapeutic applications, imaging techniques such as Single Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET), and its vital role in cancer imaging, cardiac assessments, bone scans, and thyroid disorders. The therapeutic realm of Nuclear Medicine extends beyond diagnostics, employing targeted therapies like Radioactive Iodine Therapy, Radiosynovectomy, and Radioembolization to deliver precise treatment at the molecular level. While the field has made significant strides, challenges persist, including concerns about radiation exposure and the accessibility of radiopharmaceutical production. Looking ahead, the future of Nuclear Medicine holds promise with ongoing research into new radiotracers, advanced imaging technologies, and personalized therapeutic approaches. As molecular imaging and personalized medicine continue to evolve, the precision and efficacy of Nuclear Medicine applications are expected to reach new heights.

We present a case of a 46-year-old female who was hospitalized with a 20-day history of irregular vaginal bleeding after menopause. Laboratory tests of tumor markers revealed negativity for carcinoma embryonic antigen (CEA) and carbohydrate antigen 125(CA125). Transvaginal ultrasound showed a hypoechoic mass in the cervix uterus. Fluorine-18-Cuorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) revealed a significantly enlarged cervix with an intense metabolic signal due to uptake of 18F-FDG. The patient was negative for systemic FDG metabolism in the lymph nodes and bone marrow. The subsequent histopathologic examination confirmed the diagnosis of primary diffuse large B-Cell lymphoma non-germinal centerB-cell-like (DLBCL-NGCB) of the cervix.
