History
Nuclear imaging produces images by detecting radiation from different parts of the body after a radioactive tracer material is administered. The images are recorded on a computer. In most cases the radiotracer is injected into a vein, they have no side effects. Imaging can be used to treat conditions or to evaluate how a treatment is working. The primary difference between nuclear medicine imaging and other imaging is that nuclear medicine evaluates the function of the organ compared to the anatomy. The function of the organs is referred to as this term.
What is physiology?
The Society of Nuclear Medicine was formed in 1954 in Spokane, Washington, and in 1960 the society launched its first publication of the Journal of Nuclear Medicine, which became the flagship associated with the field. In 1971, the American Medical Association acknowledged Nucs as an official medical specialty. In 1972, what board was formed?
What is the American Board of Nuclear Medicine?
Nuclear Medicine is a medical specialty involving the use of radioactive isotopes in the diagnosis and treatment of a disease. It enables clinicians to noninvasively and precisely identify specific molecular activity within tissues and organs of the body. Radioisotopes have unstable nuclei and dissipate excess energy by emitting radiation in the form of gamma and other rays. The radioisotope is introduced into the body by intravenous injection, and taken up in different amounts by different organs. Distribution is determined by recording the emitted radiation by charting the presence, size, and shape of various abnormalities in body organs. Different isotopes concentrate in different organs. The radioisotope travels via
What is the bloodstream?
FDG (Flourine-18) is labeled a derivative of glucose which is used with PET (positron emission tomography) which provides a map of where glucose is metabolized in the body. This tracer is used to transport via glucose transporters and metabolized in a concerted process. Imagining can help with various clinical indications that include dementia, seizure disorders, and new or recurrent tumors. This organ uses glucose as a source of energy.
What is the brain?
Josh Armstrong discussed ethical conflicts in the context of humanity vs. technology. As a patient becomes ill and suffers from a loss of humanity becoming very exploitable; the duty of the physician is to honor the patient's humanity. New technology is taking a central role in a patient's care. the radiologist must develop a relationship with the patient. Mutual respect must be taken by all responsible parties. The principles of ethical codes revolve around a patient's right in regard to their body during illness and health. Moral principles that govern the practice of medicine are referred to as
What are medical ethics?
Wilhelm Roentgen - a professor at the University of Wurzburg in Germany, discovered that by using cathode tubes he could generate invisible rays that drive at the speed of light. His wife - Anna Bertha - placed her hand under the invisible rays for 15 minutes and the result was the first X-ray. During experimentation, he discovered that the only thing that would stop the powerful rays were metal sheets. What metal shields radiation?
The American College of Radiology (ACR) published a set of ethical guidelines for those who practice radiology specialties. The Principles of Ethics of the ACR display 5 ethical categories in common:
1. The morally imperative
2. The morally commendable
3. The morally neutral
4. The morally odious
5. The morally proscribed
Those who practice the set ethical guidelines should extend this term to include nuclear medicine physicians or radiation oncologists.
What are radiologists?
According to the Center for Medicare and Medicaid Services (CMS) data nuclear medicine is a $1.7 billion industry. It plays an essential role in medical specialties from cardiology, to oncology, to neurology and psychiatry. The Society of Nuclear Medicine estimates that 20 million procedures are performed annually in the United States, and approximately 12 million procedures are approved and reimbursed by CMS. Based on data collected by the CNS in the United States the use of PET (positron emission tomography) is growing faster than the use of any other image modality. It is estimated to save almost $400,000 per 100 patients when compared to surgery procedures to assess and diagnose the presence of malignancy in predetermined lung lesions. These advancements are contributing to personalized healthcare. Nuclear imaging allows physicians to cost-effectively obtain more medical information that would have otherwise been unavailable. Personalized care and cost-efficiency improve this relationship with the physician-patient.
What is patient care?
Nuclear Medicine is used to diagnose and treat illnesses, conditions that can be diagnosed are:
Blood disease - Thyroid disease - Heart disease - Gallbladder disease - Lung problems - Bone problems (infections/breaks) - Kidney disease (infections/blockages/scars) - Cancer.
Treating conditions or evaluating how a treatment works is radioimmunotherapy - which combines radiation and immunotherapy. Delivers radiation precisely to an area.
There are no general rules for preparing for nuclear medicine imaging; however, most require no eating or drinking before the test. There are two ways in which a radiotracer is given
Nuclear Medicine and Radiology are constantly experiencing a rapid evolution of change: from rapid technological developments, new molecular models for disease processes, and new economic opportunities and constraints in imaging. In each area of medicine, there are ethical issues that guide the performance and decision-making of healthcare workers. The proper behavior of physicians and healthcare workers developed the ethical code. Basic ethical principles were applied to healthcare in 1976: Respect for persons, Beneficence, and Justice. This principle signifies that human beings have a special position that places them over the natural and biological position in nature, this concept determines their value and position
What is dignity?
Nuclear Medicine was first discovered in the Oak Ridge National Laboratory in Tennessee. Somewhere between 1934 when artificial radioactivity was first discovered and 1946 when radionuclides were first produced for medical use. Rosalyn Yalow, a radiochemist from New York teamed up with Soloman Berson to tag insulin with radioactive iodine tracers, in doing this she was able to track the insulin and the radioactivity as it was processed through the body. Cattle insulin was given to diabetics, she discovered that the body was attacking the cattle insulin with antibodies. The antibodies weighed down the insulin and rendered it ineffective. Today's insulin is modified to reflect "human" insulin. Why is insulin given to diabetics?
What is to regulate blood sugar?
A nuclear medicine specialist has the main responsibility of radiation protection. There are established protocols for diagnostic and therapeutic procedures, which ensure that each medical exposure is justified. Healthcare professionals must conform to a variety of regulations guidelines, and standards of practice settings to ensure patient safety. Compliance is often secured through the publication and expected observation of practice standards, policies, procedures, and rules. This federal agency is responsible for manufacturing and ultimate patient safety.

The Positron Emission Tomography (PET) imaging modality is primarily used for oncology. It utilizes radiotracers to measure the metabolic processes in the body; various changes in metabolism, blood flow, and regional chemical compositions. The tracer gets trapped in tissues depending on the affinity. Areas of higher activity indicate higher uptake and brighter spots on the images. Oncology refers to this disease
What is cancer?
As technology levels increase, the need for training or retraining in new modalities places a strain on both the teaching programs and practicing nuclear physicians and radiologists. This concept refers to self-governing and is associated with the freedom of the individual and wishes for their future life. This term also implies the capacity for individuals to make their own decisions about their lives.
What is autonomy?
Nuclear Medicine became recognized as a potential specialty in 1946. Sam Seidlin reported the success of radioactive iodine (1-131) in treating a patient with advanced thyroid cancer. Later, the use of 1-131 was expanded into applications such as thyroid gland imaging, hyperthyroidism treatments, and quantification of thyroid function. Nuclear Medicine is associated with medical chemistry, engineering, and this math-based concept with the nature and properties of matter and energy.
