  • 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.…

  • Radioisotope Tracer Research Paper

    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…

  • Neurosimaging

    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…

  • Broken Mirror Theory In Psychology

    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…

  • Explain The Signs And Early Detection Of Heart Disease

    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…

  • Radiology Research Paper

    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…

  • Brain Imaging Technology Essay

    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…

  • Cognitive Neuroscience Study

    method of looking at the physiological side of the brain had to emerge. Cognitive neuroscience was then born to identify the neural mechanisms, which are responsible for underlying cognition. These neural mechanisms are also important when it comes to manifestations in behaviour. Cognitive neuroscience helps to combine the works of cognitive science and cognitive psychology. However, it is important to consider how internal physical processes can initiate mental processes. Recently, cognitive…

  • Essay On Mild Cognitive Impairment

    consists of long range nerve fibers and glial cells. This difference creates the signal that is measured (Structural MRI). In regards to MCI, this technique can be used to see the difference in brain composition between normal, MCI, and AD brains to see if there is more degradation in certain areas of the brain as the cognitive impairment develops. Normal positron electron emission, PET, compares regular tissue to damaged or unhealthy tissue. In amyloid PET, a ligand binds to a specific…

  • Extrahepatic Tumors: A Case Study

    when it comes to detect LMs form colorectal carcinoma. Notwithstanding some advantages, there are some advantages of each form of scanning as well. The scan of CT is not viable in detecting a tumour which is believed to be less than CMs. whereas for some form of the tissues imaging of MRI is not as clear as the imaging of the CT scan is. Furthermore, it is doubly difficult to find out the difference between the images of inflammations, scar tissues form the image of tumour. MRI imaging cannot…
