Nuclear medicine uses radioisotopes to diagnose and treat patients. Diagnosis is made using in vivo imaging and in vitro and biological tests while treatment is done with radioactive sources.

In vivo imaging uses radioactive isotopes that emit gamma rays in the body which aggregate in the organs such as the brain, heart and bones due to the nature of radiopharmaceuticals. A camera that detects such distribution of gamma rays takes images to show any dysfunctional organs from a biochemical perspective. This method provides a planar image as well as the SPECT image with high resolution. In order to achieve a speedy diagnosis process for the skeletal, thyroid, endocrine, urinary tract, liver & biliary, digestive, nervous and respiratory systems, the clinic is equipped with 2 gamma cameras and thyroid uptake.

PET scan, which is widely used for the prognosis of patients, emits positrons for the diagnosis, staging and treatment effects of malignant tumors using radioisotopes In addition to the diagnosis of tumors, it is being used to diagnose neuropsychological diseases such as dementia and epilepsy as well as heart diseases such as coronary artery disease. The clinic is equipped with 1 PET-CT (16 slice).

In vitro tests precisely and accurately measure the presence of trace amount of physiological substances by radioimmunoassay using radioisotopes. This allows accurate quantitative measurement of cancer markers, body hormones such as thyroid hormones or the presence of viruses such as hepatitis.

The radioactive isotopes that emit beta rays are being used to effectively treat hyperthyroidism or thyroid cancer in addition to reducing bone pain due to metastatic cancer. Taking advantage of the fact that the radiopharmaceuticals aggregate in the target organ, this method minimizes damage to normal tissues while effectively treating diseases in the body and its application is increasing with the development of new radioactive isotopes. For effective treatments, 2 treatment rooms are being operated.

The nuclear medicine center at Dongguk University Ilsan Medical Center is dedicated to providing the best medical service by including prevention and health maintenance in the list of offered services on top of treatment and diagnosis.
