As time has advanced so has technology; the world has watches that along with telling what time it is the watch also tells us who is calling us and how we slept at night. Along with so many other amazing inventions for our daily life there have been miraculous milestones with our neuroimaging inventions; scans range from being able to tell us where our brain is functioning during a task to allowing us to catch diseases such as cancer faster than ever before. This paper explores each neuroimaging machine; MRI, MEG, fMRI, PET, and EEG.
Magnetic resonance imaging or MRI uses a magnetic field and radio waves to create detailed images of the organs and tissues within the body. The MRI creates 3D images of a section of the body being scanned, allows doctors to view the scan at all angles and all layers(Tests and Procedures: MRI). An MRI scan is noninvasive, because it is noninvasive no allergic reactions or side effects will occur, and lastly an MRI doesn’t use radiation which allows the test to be done on pregnant woman and children. Downsides to an MRI is that patients cannot have any metal on/in their bodies- bullets, shrapnel, limbs, etc.- the machine may also induce a claustrophobic response because the machine requires the patient to lie completely still and inside a narrow tube, since the patient must remain completely still children may need anesthesia. Other downsides include the heat that comes off of the MRI
