There are several methods that both measure and scan the cortical functions of the brain and they both have their individual strengths and weaknesses. In a Positron Emission Tomography (PET) scan the scanner injects the patient with glucose containing radiotracers which are radioactive and emit positrons which are then picked up by the scanner. As glucose is used for energy in the body it will travel to the brain and distributes itself to the parts of the brain need it most at that time. When it is inside the brain, the PET scanner can detect the gamma rays of radiation emitted by the radioactive glucose and produce a three-dimensional image of the brain based on the concentration of the glucose molecules inside the parts of the brain that are using it. The concentration of the glucose in the brain is influenced by the examiner by asking the patient to perform specific tasks such as making decisions, solving problems or studying memory activities. PET scanning is useful to psychologists as it gives information about the functioning of the brain and which areas are more active and respond in different ways depending on the tasks that are set. This can then be linked to explain the functions occurring based on which parts of the brain are detected by the glucose to be responding. However this technique cannot be used to measure spontaneous behaviours as the scan measures only chemical concentrations in the brain and cannot measure the electrical signals that cause spontaneous behaviour. It can also be expensive due to the fact that radioactive substances are being used. There are ethical issues associated with PET scanning as injecting radioactive glucose can affect the patient’s health and could cause diseases to occur. PET scanning is used to assess the brain activity in people who have received strokes, cancer of the brain, traumas and other brain dysfunctions to see of what parts the brain are no longer functioning due to these diseases.…

The MRI measures variations in magnetic fields. It then computes and depicts cross sections of organs such as the brain with great clarity. It is noninvasive and allows for visualization of all but the tiniest brain structures. Its major problem is the claustrophobic reaction some people have to the procedure. PET scans track substances as they are metabolized by the brain. They can show how the brain is functioning. They can help identify areas that are not functioning normally that might not be obvious anatomically. Their major problem is low-fidelity pictures that have so far limited their value. The fMRI measures changes in blood flow in the brain. It is possible to map ongoing psychological activity and show which areas of the…
Although PET offers some advantages over SPECT according to Loong and Anagnostapoulos (2004) “the American college of Cardiology/American Heart Association guidelines for the management of patients with stable angina recommend the use of adenosine or dipyridamole SPECT MPI as the preferred imaging modality for patients with LBBB” (p. 4). Both SPECT and PET capture photons that are emitted by radiotracer they then convert the information into data that’s digital which represents the tracer uptake as well as the location of the emission of the heart.…
An issue with PET and MRI scans is that the patient has to stay still, and cannot move as this could interfere with the investigation and not give accurate results. So this will not be the easiest procedure for people who are claustrophobic with the MRI scan and the space where the person can go between the scanners is not the biggest, so there will be no room to move and is not very beneficial for the obese. There are scanners which are made to be bigger and have…

Diagnostic Imaging is medical tools used by doctors to see inside our bodies without actually opening the body. Diagnostic imaging can involve the use of radiation which could be dangerous if exposed to large amounts of. Diagnostic imaging allows doctors to find tumors, broken bones, pneumonia, etc. In general, diagnostic imaging is very helpful.…
CT scans has been used since 1980. In the recent year, CT scan use increased from 3 million CT scans to 70 million by 2007. According to this article, CT scans alone will cause nearly 30,000 unnecessary cancer cases (about 2 percent of cancer cases), which will lead to about 14,500 deaths.CT scan of the chest delivers 100 times the radiation of a conventional chest X-ray. This article based in many other studies that has been done concerning the increase of using the CT scanner. According to this article "About one-third of all CT scans that are done right now are medically unnecessary … Virtually anyone who presents in the emergency room with pain in the belly or a chronic headache will automatically get a CT scan. Is that justified?” I totally…
Computed tomography (CT) and magnetic resonance imaging (MRI) are both diagnostic tests that provide us with high-resolution pictures of any area of the body. Both tests use computers to construct pictures to view within the body. Both of these tests are non-invasive procedures designed to provide medical professionals with a better understanding of the patient’s condition. There are, however, inherent differences in these tests’ mechanisms, sophistication, and application (“What is the Difference Between CT and MRI?”).…
PET is used in conjunction with small amounts of radio-labeled compounds and a gamma camera to pick up and record the images that come from PET scans. A radioactive compound is inhaled or injected into the patient, and it accumulates in tissues. As the atoms in the compound decay, they release positrons, which, when they collide with electrons, both the electrons and positrons are annihilated, and two photons (light particles) are emitted. (See the image on the right). The photons are picked up by a detector ring on the PET scanner, and the computer uses the information to generate three-dimensional images that represent the bioactivity where the compound accumulated and released light (Christenson, 2014). Most of the time, the injection received by patients who undergo PET scans is a radioactive form of F- fluorodeoyglucose (FDG), which is metabolized in the same way that glucose is. Malignant (harmful) cells have faster metabolisms than normal cells, so they require more sugar to fuel their rapid metabolism. Thus, they use more of the F-FDG, emitting more of the photons detected by the gamma camera (Scanning the scans,…
In order to draw a better conclusion on how well our campaign was going to do, we drew conclusions using the SWOT analysis model. SWOT analysis is a powerful tool that looks into a business Strengths, Weaknesses, Opportunities, and external Threats. A huge strength of our campaign was the sole objective of our campaign, to help a charity in need. By having all of our profits go to the Houston Humane Society, people could tell we were just doing this for a greater cause. Another strength with the Pro Pet Rescue campaign was our marketing opportunities. Being able to tweet to about 600 people online to advertise our campaign gave us an advantage over other campaigns. A major weakness in our campaign was the lack of experience in creating a small…
