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…
PET is a nuclear medicine, working imaging ability that creates a three-dimensional image of functional processes within the human body. [1] First, chemicals which emits gamma radiation are injected into the human body, then; the system detects pairs of gamma rays emitted indirectly by a tracer to show images of bones and organs. These substances are injected into the body, and are usually tagged with a radioactive atom.[1] Doctors use this device to create images of bones and organs of the…

Introduction Brain imaging techniques have been a prominent resource in developing research associated with several cognitive disorders including: Alzheimer’s disease, concussions, MCI, etc. Researchers have been developing novel approaches to help develop solutions and/or gain better insight for what disease, injuries, and impairment have on the brain. One of the more recent techniques that has been developed is fMRI. One of the cognitive issues it can look at is mild cognitive impairment,…
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…
using PET/MR and seeing how their body is functioning of course we can not read the results but the patient will have a better understanding what's going on in their body. PET is a type of nuclear medicine imaging procedure. PET stands for positron emission tomography it allows to detect disease in patients. PET…
bio-signatures of treatment, novel response for and treatment-resistant depressions, identify potentially relevant novel drug targets, and identify potentially relevant novel bipolar disorders as (magnetoencephalography and polysomnography, positron emission tomography, functional MRI and magnetic resonance spectroscopy). The article's thesis statement is Chief of the Experimental Therapeutics and Pathophysiology Branch. The article…
A positron emission tomography (PET) scan is an imaging test used by doctors to check for the disease in the patient's body. This PET scan also can use to measure blood flow, oxygen use and can detect cancer, heart problems, brain disorders and another. PET scans use radioactive materials called tracers to find diseases in the body and it will shows how organs and tissues are working. Stacy Simon reported annual statistics reporting from the American Cancer Society shows the death rate from…
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…
medical boards were formed as a result, such as the American Board of Nuclear Medicine, and the American Osteopathic Board of Nuclear Medicine. Nuclear medicine was cemented as a stand alone specialty in 1974. Imaging techniques such as positron emission tomography (PET) were developed in the 1980’s by David E. Kuhl and Roy Edwards. The invention of the PET also led to the invention of other imaging techniques such as SPECT and CT…
