Positron emission tomography

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,…

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…

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,…

Cognitive psychology is the study of human mental processes that occur within the mind. It looks at such internal processes such as, memory, perception and attention. It came about in the 1950’s as a result of the behaviourist approach being flawed; internal mental processes cannot be observed. Therefore, from this an alternative 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…

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…

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…

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…

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…

behaviour can be provided as well, even though the cause-effect relationship may not be able to be established because of the complexity of the structure of the brain. There are different types of brain-imaging technologies. For example, the PET(positron emission topography), the MRI(magnetic…
