  • Essay On Nuclear Chemistry

    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…

  • The Role Of Imaging In Nuclear Medicine

    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…

  • 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…

  • 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…

  • Cognitive Neuroscience Study

    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

    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 substrate and it is…

  • What Can Neuroscience Tell Us About Evil Analysis

    Summary In the Article, What Can Neuroscience Tell Us about Evil?, the author Richard Brandt discusses how the advances in neuroscience reveal how the brains of psychopathic or sociopathic people are different. For example, some brain-imaging techniques show that not only do some of the psychopathic or sociopathic minds lack emotions such as empathy, but also, some techniques expose that these certain sections of the brain are inactive (Brandt, 2007). Furthermore, fMRI scans illustrate that in…

  • PET/Mr In Nuclear Medicine

    In my paper I’m going to write about PET/MR how it was developed and how they both work together. Also on the individual level what PET does and what MR does separately.The importance in the nuclear medicine and how it help the patients. And the risk that it has on the patient's. Both are very important in Nuclear Medicine because we use this on daily bases in our day to day. It helps detect disease in patients and we treat them by using PET/MR and seeing how their body is functioning of course…

  • Extrahepatic Tumors: A Case Study

    It was recorded that 12 out of 35 patients, suffered from extrahepatic tumour. This was revealed by PET/CT combined and by CT scan single-handedly. The extrahepatic tumours in two of the patients were not detected by PET and PET/CT; those were recorded to have node of 2 –cm lymph in the hepatoduodenal ligament. It is furthermore, true that both forms of the scans (CT and PET/CT) reported extrahepatic tumour in patients that did not have it at all. The CT scan reported it in 3 out of 23 patients,…

  • PET Disadvantages

    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…
