Positron emission tomography

In 1997 Adrian Raine conducted a study that focused on brain abnormalities in murderers that were shown by the use of positron emission tomography (PET). “The aim of his experiment was to see if murderers who pleaded not guilty by the reason of insanity (NGRI) showed signs of brain abnormalities with PET scans. Raine used 41 participants, 39 of which were male and 2 of which were females. The prisoner’s reasons for insanity varied. Six said they were schizophrenic, 23 said it was due to a head injury, 3 blamed drug abuse, 2 claimed it was an affective disorder, 2 gave the excuse of epilepsy, 3 said the insanity was due to hyperactivity or learning difficulties, and 2 claimed to have a personality disorder. There was a control group that was also selected.…

Positron emission tomography (PET): is an anatomically based measurement that utilizes small radioactive tracers that are able to identify and determine glucose and metabolic levels within the organs of the body. This type of tomography could be used in a concussion assessment to determine the metabolic activities and glucose levels of the brain, as these levels are important and often become altered following a concussion. Functional magnetic resonance imaging (fMRI): is an anatomically…

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…

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…

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…

test or Electrocardiogram (EKG) is not sufficient to help people who may experience a heart attack in spite results of normal cholesterol. Newer imaging technology such as, CT scans, MRI, 3-dimensional echocardiography (3-D echo) and PET/CT scans have changed the game by being less invasive and less expensive. Computed Tomography Angiography (CTA) is a diagnostic tool used for early detection to find small blockages in coronary arteries. CTA is so great that doctors can rule in or out…

The Technology of Radiology There is a lot of technology included in Radiology. Radiologists are medical doctors that diagnose and treat diseases “using medical imaging technologies.” They use many different tools and machines to diagnose and treat people. Some of the technology used in radiology are catheters, wires, small instruments and tools, scanners, and remote viewing systems. The three most common scans are CT, MRI, and PET. There are many different types of x-rays, the most well known…

TIME Magazine named the PET scan the medical invention of the year in 2000, and Dr. David Townsend and Dr. Ronald Nutt are credited as the individuals behind the paramount device. A positron emission tomography (PET) scan is a nuclear medicine imaging test that aids in revealing how well a human’s organs and tissues are functioning; the scan can measure an individual’s oxygen use, glucose metabolism, blood flow and much more. The significance of this function is monumental as it essentially…

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 balance…

In the past three decades neuroimaging has revolutionized the world of neural sciences. First, it was the introduction of the computerized axial tomography in the 70s that gave information of anatomical structure. In the early 80s, the development of positron emission tomography gave the neural sciences the ability to produce 3D images of functional processes and magnetic resonance imaging provided an alternative to CT and X-ray imaging without the radiation exposure. Lastly, the domination that…
