complementary medicine (complementary and alternative medicine (CAM)) a large and diverse set of systems of diagnosis, treatment, and prevention based on philosophies and techniques other than those used in conventional Western medicine, often derived from traditions of medical practice used in other, non-Western cultures. Such practices may be described as alternative, that is, existing as a body separate from and as a replacement for conventional Western medicine, or complementary, that is, used in addition to conventional Western practice. CAM is characterized by its focus on the whole person as a unique individual, on the energy of the body and its influence on health and disease, on the healing power of nature and the mobilization of the body's own resources to heal itself, and on the treatment of the underlying causes, rather than symptoms, of disease. Many of the techniques used are the subject of controversy and have not been validated by controlled studies.
emergency medicine the medical specialty that deals with the acutely ill or injured who require immediate medical treatment. See also emergency and emergency care.
experimental medicine study of the science of healing diseases based on experimentation in animals.

nu·cle·ar med·i·cine

the clinical discipline concerned with the diagnostic and therapeutic uses of radionuclides, including sealed radiation sources.

nuclear medicine

n.
The branch of medicine that deals with the use of radionuclides in diagnosis and treatment of disease.

nuclear medicine

a medical discipline that uses radiation emitted by radioactive isotopes in the diagnosis and treatment of disease. Forms of radiation important in nuclear medicine include alpha and beta particles, gamma rays, and x-rays. Radioactive elements used in nuclear medicine, called radionuclides or radiopharmaceuticals, are produced artificially. Radiopharmaceuticals are used as tracers for assessing the structure, function, secretion, excretion, and volume of a particular organ or tissue. They are also used to analyze biological specimens and to treat specific diseases such as thyroid cancer. An important component of nuclear medicine is imaging, which involves administering radiopharmaceuticals to a patient orally, intravenously, or by inhalation to localize a specific organ or system and its structure and function. Scanning instruments convert the radioactive emissions into an image of the organ or system.

nu·cle·ar med·i·cine

(nū'klē-ăr med'i-sin)
The clinical discipline concerned with the diagnostic and therapeutic uses of radionuclides, excluding the therapeutic use of sealed radiation sources.

nuclear medicine

The medical specialty based on the use of radioactive substances for diagnosis and treatment of disease. Radioactive isotopes can be incorporated into a wide range of compounds that can be given by mouth or by injection. Specific radioactive elements or compounds containing them are selectively concentrated in different organs, or in particular disease tissues, and their distribution and local concentration in the body can then be detected and measured by an instrument called a GAMMA CAMERA. Certain cancers, for instance, can be detected anywhere in the body and appropriate treatment directed to every site of the disease.

Nuclear medicine

A subspecialty of radiology used to show the function and anatomy of body organs. Very small amounts of radioactive substances, or tracers, are detected with a special camera as they accumulate in certain organs and tissues.

1. any drug or remedy.
2. the nonsurgical treatment of disease.

food animal medicine
the veterinary medicine of the domesticated farm animals, including cattle, sheep, goats, pigs, poultry and, with some flexibility, horses, that are used for and in the production of human food and of fiber used in human raiment. It includes the increasingly important segment of preventive and herd/flock medicine.
nuclear medicine
that branch of veterinary medicine devoted to the use of radionuclides in the diagnosis and treatment of animal diseases.
veterinary medicine
the science and art of diagnosis, treatment and prevention of the diseases of animals, and the maintenance of normal health. This classic definition is now expanded in many areas to include the promotion of financially optimal production. It consists mostly of prevention of wastage caused by disease, but also includes inputs from nutrition, genetics, housing, and other management disciplines. See also veterinary medicine.
