Compare the different methods of neuroimaging. How are these methods alike and different?According to Argosy (2008) about different methods of neuroimaging include X-rays, CT, MRI, PET, fMRI, and EEG.
In x-rays, a beam of light is passed finished the object or person onto a photographic plate. Pinel (2009) This beam is absorbed differently by different materials. Usually, hard materials such(prenominal) as metal and bone absorb it quite swell and really show up on the x-ray photograph. However, different materials, such as clothing or soft wander do not show up as well, beca consumption they do not absorb as well.
A CT, Computed Tomography, study uses x-rays in rotation to take and combine many individual x-rays most the brain. Then the machine is moved along the axis of the patients body. Pinel (2009) and adventually the training is combined to make a 3-D photo of the brain.
Next, an MRI, or Magnetic Resonance imaging, which uses magnets and measures waves produced by these magnetic fields. Pinel (2009). The MRI scope is ideal for showing special locations in the brain structure. Pinel (2009). I was recently exposed to this with a relative of mine who was brainsick and we feared had a stroke. They first took a CT scan, further, a hardly a(prenominal) days later wanted to take an MRI. I asked the adulterate why this was, and he said that although a CT scan should pick up if thither was a big pussycat of blood, the MRI machine would pick up blockage images and they could use it to scan in finer detail.
Thankfully, his test results came back prohibit for stroke, but it was a good educational experience on how each procedure can produce unique but useful sets of information.
PET, or Positron Emission Tomography, differs from the previous mentioned scans in that it...
Good information was provided but I would have liked to devour more comparison as the introductory statement tell it would describe how they are alike and different. Instead, paper describes each composition without much detail. Some good info in there though!
