Nuclear Medicine is a branch of medicine that uses radioactive medicines for diagnosis and treatment of various diseases. A small dose of radioactive tracer or radioactive medicine is administered into the patient body by injection/ingestion/inhalation for analysing the physiology of various organs or tissues of the body. Nuclear Medicine studies and therapies play very useful role in early diagnosis and targeted treatment of diseases like various cancers, cardiovascular disease, thyroid disease, kidney disease, and neurological diseases.

Department of Nuclear Medicine in Mar Sleeva Medicity Palai is equipped with United Imaging uMI 550 Digital PET CT (80 SLICE) system and Siemens Symbia Gamma Camera for imaging.

In theranostics, there are 4 therapy rooms for different radionuclide therapies, which includes I-131 radioiodine therapy for hyperthyroidism and thyroid cancers, Ga-68 PSMA for diagnosis of prostate cancer, Lu-177/Ac-225/Tb-161 PSMA for treatment of prostate cancer. For diagnosis of neuroendocrine tumors, Ga-68-DOTANOC is used and Lu-177/Ac-225/Tb-161 DOTATATE for treatment of neuroendocrine tumors. These radionuclide therapies are targeted at specific cancer cells with minimal harm to normal cells, giving good disease control with better quality of life.
