Single photon emission computed tomography

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…

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…

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…

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…

Computed Tomography A CT scan is produced using plenty of x-ray images from lots of different angles using computerized axial tomography (cat). It produces cross-sectional images or slices of bones, tissues and the angio portion which is produced through a CTA (cat scan angio) allows professionals to view the blood vessels. It is a great medical tool, with interesting history and of course like everything else in the worldwide medicine, it has its pros and cons. A Computed Tomography scan is a…

research strategies in order to observe the effect it has on the brain and its functioning (Wilson, 2013). Several methods of technology are available that record and measure brain function like the electroencephalography (EEG) or the single photon emission computed tomography (SPECT) but I feel the most useful method would be the functional magnetic resonance imaging (fMRI) due to its ability to be used repeatedly on patients in a noninvasive manner. The fMRI can localize specific brain…

Overview Background Transient global amnesia (TGA) has been a well-described phenomenon for more than 40 years. Clinically, it manifests with a paroxysmal, transient loss of memory function. Immediate recall ability is preserved, as is remote memory; however, patients experience striking loss of memory for recent events and an impaired ability to retain new information. In some cases, the degree of retrograde memory loss is mild. Many patients are anxious or agitated and may repeatedly ask…

right halves and the axial are dividing the body into upper and lower halves. There are modern techniques used in Digital radiography (X-ray), ultrasound, microscopic imaging (MI), Computed tomography (CT), Magnetic resonance imaging (MRI), Single photon emission computed tomography (SPECT) and Positron emission tomography (PET). MRI is used in the brain for the purpose of bleeding, aneurysms, tumors and…
