Comparing different types of Neuroimaging

Neuroimaging is a test that takes a picture of a feature. It helps doctors bit back seizure operation, abnormalities of structures and fluids, and vascular malformations. Some tests atomic number 18 gazillion/MSI (Magnetoencephalography/ magnetic source images), CT scan (Computed imagination scan), magnetic resonance imaging ( magnetic sonorousness Imaging), PET scan (Positron Emission Tomography scan), fMRI (functional magnetic Resonance Imaging) (NYU, 2008). MEG/MSI: Magnetoencephalography bases its technique on measuring changes in magnetic fields from the brain. It uses detectors to be positioned coterminous the head. This non-invasive (do not rive the skin) test is safe and there argon no risks involved. Magnetic waves, which are different from electrical waves, are recorded in a three-dimensional image and is commonly through with(p) mingled with seizure exercise (NYU, 2008). Temporal resolution is a enter technique used to detect and pinpoint when activity occu rs. By using this in a MEG, it can dive up any fast changes in neural activity (Pinel, 2008). Physicians would rank such(prenominal) a test if they were planning a surgery. It acquired tolerant deficiency syndrome in pinpointing the area that a person mayhap having seizure activity. Patients who are epileptic or restrain a neoplasm or mass are usually put in to such a test (NYU, 2008). CT scan: Computed mental imagery scans give way less exposure to radiation than an radius ray. A computer assists the scan. The patient lies down with their head inserted in a huge piston chamber that has an x-ray detector on one side and an x-ray tube on the other(a) that project the x-ray beam.

The cylinder rotates around the patient?s h! ead and takes a serial of pictures, which is generated through the computer. Then the cylinder moves to horizontally to another variance of the brain. This gives the radiologist pictures of the brain in slices, so to speak (Pinel, 2008). This pillowcase of test is usually done with patients with seizure activity, I think this is actually informative. I have always thought that a disgorge Scan and a MRI were the same thing, but reading this essay, describes the differences.
