PET Scan Research Paper

The photons are then tracked by a tomographic scintillation counter, and the information is processed by a computer to provide both image and data on blood flow and metabolic processes within bodily tissues. PET scans are particularly useful for diagnosing brain tumor and the effects of strokes on the brain, along with various mental illnesses. They are also used in brain research and in mapping of brain functions.

PET is the only method that can detect and display metabolic changes in tissue, distinguish normal tissue from those that are diseased, such as in cancer, differentiate viable from dead or dying tissue, show regional blood flow, and determine the distribution and

Different maps are taken of the brain in order to determine if there are any problems with the brain. An electroencephalogram (EEG) is used an amplified read out of the brain waves. A magnetic resonance imaging scan (MRI) gives a detailed picture of the brain’s soft tissues. It also shows the structure of the brain. A function magnetic resonance imaging scan or function MRI (fMRI) shows the function of parts of the brain as well as the brain’s structure. It also has the ability to show when a person is lying. Scientists also use a neuroimaging technique called a positron emission tomography scan (PET scan) to view the brain. (Barron’s AP Psychology 6th Edition) The PET scan shows each brain area’s consumption of chemical fuel which is glucose. There is a scale for the PET scan to determine activity in the brain when performing a certain action. The colors range from purple to red, purple represents no activity while red represents very high activity. The PET scan can

In nuclear medicine diagnosing techniques, a very small amount of radioactive material is introduced into the body. Because medical isotopes are attracted to specific organs, bones or tissues, the emissions they produce can provide crucial information about a particular type of cancer or disease. Information gathered during a nuclear medicine technique is more comprehensive than other imaging procedures because it describes organ function, not just structure. The result is that many diseases and cancers can be diagnosed much earlier.

The PET scan also will show two and three-dimensional images of the brain; however, the PET scan measures brain activity. This is done by injecting radioactive isotopes into the blood stream. The isotopes attach to

When a patient goes in for an EEG, the location the electrode will be place on is cleaned and hair is parted. The number of electrodes placed on the scalp is normally between 12 and 20 depending on the purpose of the EGG. PET - Define: According to Brian Krans of Healthline, PET scans, or Positron Emission Tomography, are a type of imaging technique that uses radioactive tracer dye to analyze different organ function. The dye is injected via a vain in the arm and absorbs into organs and upon scanning, a doctor can see how well that organ is working.

FDG-Positron Emission Tomography (PET) is not routinely performed as part of the diagnostic work up for Alzheimer’s disease. Thus, it is not the standard of care to rule in or rule out a diagnosis of Alzheimer’s disease.

What additional laboratory or radiological tests would be indicated and why? What would you expect to find?

What They Do Radiologic technologists are also known as radiographers. For this job you do diagnostic imaging examinations, such as x-rays on patients. MRI technologists use magnetic resonance imaging scanners to create diagnostic images. One duty for radiologic and MRI technologists is to adjust and maintain the imaging equipment. They need to make sure all the machines are working properly so nothing goes wrong.

When it comes to medical imaging, there are several different options to choose from for different testing. There are similarities and differences; pros and cons to each. This paper will discuss MRI, CT, and ultrasound. They each have important things to know regarding radiation dose, cost, and reasons to use one over another.

Anyone who wants to become a CAT scan technologist will need to complete a degree that is accredited by the Joint Review Committee on Education in Radiologic Technology (JRCERT). Fortunately, there are almost 600 accredited radiology programs in the country. These include two-year degrees in radiology technology that include classes in radiation safety, medical terminology, patient positioning, radiographic procedures and anatomy and physiology.

After being away for my first year of college, I finally got to see what this world is full of and the plethora of opportunities that are out there. My academic goals consist of completing my requirements at Monterey Peninsula College and earning my Associates Degree, then attempt to get into Cabrillo College’s Radiology Certification program to get my life started. My vocational goals are to get certified as a Radiology Technician, then eventually go a step higher and become a Radiologist. During my college experience, I have experienced what it is like to “wear many hats.” I am a full time college student and athlete, as well as working to help pay off my education. It was a rough start trying to find the time to balance everything,

Before the PET scan the patient is given an injection containing a small amount of FDG. The patient then must sit quietly for about 60 minutes. During this time they must sit and relax. They are not get up and walk around, talk, read or do anything else that would require them to

The PET scanning is particularly useful in detecting cancer because most cancer cells use more glucose than normal tissues. In lung cancer, pet scans are sometimes used to observe for cancer in particular areas such as the lymph nodes, in the chest or to demonstrate the spreading activity of cancer cells to other areas the body. This would help the doctor to take a further decision about the treatment of a

• A PET (positron emission tomography) scan may help to show cancer activity in some other parts of the body. This can be helpful for “staging” the cancer (see
