Role of Nuclear Medicine in the Field of Gastrointestinal Diseases Essay

Role of Nuclear Medicine in the Field of Gastrointestinal Diseases - Essay Example Through imaging the physician can advice the patients with such diseases the cure and treatment. With the help of Nuclear Medicine Imaging, the imaging of IBD may be performed with In-111Leukocytes and Tc-99m Leukocytes. Nuclear Imaging can assess the conditions and situation of the gastrointestinal tract of the patient. With detailed observation the physician can advice the patients on what medicine to take to cure the said disease. Medicine is the science and art concerned with treating diseases so with preservation of one's health. It is a branch of healing art that deals with restoration of life and curing diseases by administration of drugs. Medicine is a very wide subject but it all includes all the sciences that are under the healing art and all varieties of curative treatment. Not only is it all about treating but also about preventive and the discussion of causation (Universal Encyclopedia, 1993). The development and classification of medical science have proceeded by gradual steps from very early times. The year 1543 marks an important point in the development of modern medicine. It was Andreas Versalius who published De Humani Corposis Fabrica (The Fabric of Human Body) in that year. It was a first great achievement for in that book the real structure of human body was revealed. Versalius undermined the widespread of reverence for authority in science and prepared a way for independent observation in anatomy and medicine. After that achievement there was a lot of upgrades in the field of medicine. The works and achievement of Pasteur in the field of Microbiology, Mendel in the field Genetics, and Darwin in Evolutionary Biology has greatly influenced and advanced the field of Medicine. As Medicine has been developing into more knowledge about the art of healing researches and more studies have been done. Among to its advancements are the discovery of tissue grafting. Transplants of organs are now possible and have saved many lives already. Born with the improvement in the field of Medicine is Nuclear Medicine. This field of Medicine is a science of healing that uses radiation to provide or give information about the person's anatomy and the functioning activity of the specific organs. With the information given to the physician, the doctor can provide and recommend proper diagnosis and treatment. Examples of conditions that can be checked with this field are cancer, heart diseases, thyroid disorders, bone disorders and gastrointestinal diseases (Nuclear Imaging, 2006). This field of Medicine is actually a sect specialty with in the field of radiology. The diagnostic examination that results from the images of body anatomy and functionality is comprised in this field. Nuclear medicine is a subspecialty within the field of radiology. The images are developed based on the detection of energy emitted from a radioactive substance given to the patient, either intravenously or by mouth. Generally, radiation to the patient is similar to that resulting from standard x-ray examinations (Nuclear Medicine, 2006). The substances used in this kind of practice are radio nuclides (radiopharmaceuticals). During examinations the radioactive substances are administered to the patience and the radiation emitted is then measured. Mostly of these examinations involves the formation of an image using a gamma camera. Nuclear medicine can
