Single photon emission computed tomography

chemistry in medicine are discussed, it is vital to study the chemistry of nuclear and radioactivity. A nuclide consists of protons and neutrons in any configuration. Most nuclides are unstable and spontaneously release energy. Sometime subatomic particles are also released in order to reach the level of more stability. This process of attempt to go from unstable to stable state is the key for radioactive decay. We call the unstable nuclides radionuclides. In the mid- 20th century medical radionuclide production highly used reactors, accelerators and cyclotrons. Among the 1500 nuclides that are available, reactor-produced radionuclides are usually electron rich. This property result for the nuclides to decay by β negative emission that was used for cancer therapy. Some reactor-produced radionuclides were used for nuclear medicine imaging. The other aspect of medical radionuclide production was…

Nuclear medicine is used by physicians all over the world, pre-dating Computed Tomography (CT), Magnetic Resonance Imaging (MRI), and Ultrasound technology. Tests are conducted using pharmaceuticals in conjunction with specific mechanical imaging, allowing optimal diagnosis for various conditions. Nuclear medicine allows doctors to see inside the body in ways that X-ray, CT, and MRI alone cannot, providing the most accurate way to study and diagnose specific abnormalities within the body’s…

A great example of these improvements is the possibility of diagnosing Alzheimer’s before symptoms occur. An article named “Alzheimer's and Dementia Testing for Earlier Diagnosis” written by the Alzheimer’s Association talks about the huge benefits that come out of targeting Alzheimer's in earlier stages before causing irreversible brain damage. The Alzheimer's Association wanted to find potential biomarkers that will allow to detect early stages of the disease, and so far Brain…

theories in psychology that can explain the mental activity because the mind is one of the most sophisticated and complex organ to study and analyze. Neuroscience and clinical psychology have often moved in parallel, avoiding as much as possible points of contact but still moving very often to the same direction because they are anchored to each other having a common object of study: the human mind related to the human behavior. Many research attempts entering the dialogue between neuroscience…

How threatening it might sound, nuclear medicine is a very common type of treatment, as “On average, one in every two Australians can expect at some stage of his or her life to undergo a nuclear medicine procedure,” (Australian Nuclear Science and Technology Organization). It may come as a surprise, but these include Nuclear Imaging such as MRI (Magnetic Resonance Imaging), Pet scans, CT (Computerized Tomography) CAT (Computerized Axial Tomography). And no it is not A green liquid in a capsule…

Early brain imaging studies of musical imagery used PET (positron emission tomogra- phy), which has now been almost completely replaced by fMRI. PET and fMRI each have their pros and cons as methods for functional brain imaging. PET works by com- bining several tricks. Typically, subjects are injected with 2-deoxyglucose, a modified form of sugar that is transported through the bloodstream to cells just like glucose, but cannot be metabolized. As a result, 2-deoxyglucose builds up rapidly in…

(Mayo Clinic 2-4) In order to obtain a diagnosis, a physical exam will be completed. If a loss of consciousness occurs, it is important to assess and manage their airway, support their breathing, and maintain circulation. (Cifu 4) Once the patient is stable, their speech will be assessed and their memory of the events will be determined. The medical professional will more than likely check the injured person’s pupils for size and make sure they are equal in both eyes, complete coordination and…

Discuss the use of brain imaging technology in investigating the relationship between biology and behaviour The function of this paper is to review, in an unbiased way of brain imaging technologies in investigating the relationship between biology and behaviour. Brain imaging technologies, with their advantages and disadvantages: PET scan/Positron Emission Tomography scan What it is: A PET scan, or Positron Emission Tomography scan is a scan that detects positrons that are emitted from…

This article is considered one of the most important articles released in the nuclear medicine field because it popularized the practice. Widespread use of nuclear medicine began in the early 1950’s. Radionuclide knowledge expanded and the first imaging techniques were implemented with this new knowledge. In 1971 nuclear medicine was officially recognized as a medical specialty. Many medical boards were formed as a result, such as the American Board of Nuclear Medicine, and the American…

1a. The title of the article is ‘Are Pet Owners Really at Greater Risk of Cancer?’ The source of the study is from the website ‘Psychology Today’ under ‘Animal Behavior’. The research included in the article is from the University of Arizona. 1b. The study by University of Arizona was conducted via existing medical data collected from a project called ‘Women’s Health Initiative (WHI)’. This data included medical data from over 120,000 women. The research team wanted to investigate the chances…
