Nuclear Medicine Positron emission tomography/computed tomography (PET/CT) is a rapidly growing modality that has made a tremendous impact in the care of patients with cancer. PET scans use a small amount of a radioactive substance, or tracer, to show differences between healthy tissue and diseased tissue. The most commonly used tracer is 18F-FDG (Fluoro-deoxy-glucose). The combination of PET/CT provides complete information about both structure (CT) and function (PET) in the human body. Application of PET: Oncological Application (>95%): Lymphoma, Head and Neck Cancers, Lung cancer, Breast cancers, RCC, Gynaecological malignancies, Metastasis, Carcinoma of Unknown Primary etc. Useful for: Diagnosis of Malignancy Staging of various cancers Response Evaluation after Chemotherapy, Radiotherapy, Surgery or Immunotherapy Restaging Surveillance PET for guided biopsy etc. Non Oncological Application (~5%): Neurology: Dementia & Epilepsy (Temporal lobe epilepsy) Cardiology: Cardiac Viability, Infection of transplanted Valve Infection and inflammation: Sarcoidosis, Tuberculosis, Vasculitis, Polymyalgia Rheumatica (PMR), Relapsing Polychondritis, etc. Pyrexia of Unknown Origin (PUO)
