The department of Nuclear Medicine at Inha University Hospital operates PET-CT. PET is an item of nuclear medicine equipment that can image our body's metabolic state after administrating a radiopharmaceutical composed of a glucose analogue and a positron-emitting radioisotope. This examination detects the metabolic abnormalities that occur ahead of anatomical alterations in the process of disease progression. PET/CT is the latest imaging tool that can detect diseases earlier than other imaging modalities by combining the benefits of PET and CT. PET can detect abnormalities of the body's metabolic activity, while CT can detect anatomic abnormalities. As such, PET/CT's great strengths have contributed to the simplification of the diagnosis process, the detection of cancer at an early stage, and the evaluation of distant metastasis, more accurate and faster tumor localization than PET, simultaneous diagnosis and the staging of cancer, and the direct application of test results to therapy.
