Nuclear medicine is a medical speciality that uses small amounts of radioactive material in the diagnosis and treatment of the disease in early stage like heart disease, neurological disorders, several types of cancer and other abnormalities of the body. Molecular imaging includes the field of nuclear medicine, which uses very small amounts of radioactive materials (radiopharmaceuticals) to diagnose and treat disease. In nuclear medicine imaging, the radiopharmaceuticals are detected by special types of cameras that work with computers to provide very precise pictures of the area of the body being imaged. Nuclear medicine can also be used to treat certain types of cancer and other diseases.
