What is nuclear medicine? And what does it treat?

Physiologic study. Nuclear medicine involves using internal irradiation in order to define function of heart, lungs, bones, liver/spleen, stomach, thyroid gland, lymph system, kidneys, bladder, brain, parathyroid gland and gall bladder. Some isotopes are injected iv, inhaled, and some ingested. Isotopes of higher doses are used to treat thyroid diseases. Amount of irradiation controlled for individual & environment.
Nuclear. Nuclear medicine is a branch of radiology and is medical specialty. Nuclear medicine uses radioisotopes to evaluate physiological activity of both normal body organs as well as of malignancy. With a few exceptions such as the use of contrast xray, ct, us or MRI for the most part study the anatomy and anatomical changes associated with diseases. Nuclear medicine studies physiological processes. This may involve study of contraction of the heart to evaluate for cardiac dysfunction, flow of cerebral spinal fluid to evaluate for potential obstruction, contraction of the gallbladder to find out why some has abdominal pain after meals. It can also evaluate whether a tumor or growth exhibits certain aggressiveness by seeing how much sugar it takes up comparing to normal tissues and whether that growth has spread elsewhere in the body. Nuclear medicine can also be used to treat a few disease. This is particularly in thyroid diseases where iodine 131 can be used to ablate the thyroid gland and or some of the thyroid cancers. There is a subset of nuclear medicine that uses molecular imaging where a molecule is used to target a certain particle or cells in the organ or tumor.

Nuclear. Nuclear medicine is a branch of medical imaging that uses injected or injested radioactive isotopes to make diagnoses. Unlike xray images, cts, mris, and ultrasound studies that show anatomy, nuclear medicine studies show the phyiological processes that are occurring behind the scenes. A ct might show a fluid collection, but a nuclear medicine scan using radiolabeled white blood cells can tell you whether it's infected. Ct, mri, or ultrasound might show a mass in the liver, but the radioactive sugars used in a nuclear pet scan can tell you whether it's a malignancy.
Imaging physiology. Nuclear medicine is a medical specialty using radioactive drugs to image physiology, or how the body works, as opposed to imaging like x-rays, ct or mr, which image the anatomy, or structure of the body. Nm is mostly diagnostic, but can be for therapy, as in treating thyroid cancer and hyperthyroidism with radioactive iodine. Nuclear radiology is a subspecialty of radiology, similar to nm.
