Tesla was an inventor, engineer and physicist who found the Rotating Magnetic Field. This brought to light the idea that the opposite poles of a magnetic field rotate around an axis, changing direction at a constant rate with specific angles. Combining Tesla’s discovery with modern technology, the MRI machine was created. The acronym MRI stands for Magnetic Resonance Imaging, but in some places, it is called Nuclear Magnetic Resonance Imaging. This machine is used commonly in medicine to…

Neuroimaging is a technique that produce images of brain without any direct contact with the inside of the body such as internal surgery, incision of the skin. Neuroimaging technology become a powerful tool for both research and medical diagnosis. Because these technologies enable noninvasive visualization of the structure and functional segments of the brain. The field of neuroimaging has advanced rapidly day by day due to the development in technology and computational methods. The…

Numerous studies have been conducted on MRI being a useful tool in prenatal imaging of the posterior fossa. Gurbaud (2004) suggests that MRI is useful as a complementary investigation to US in three particular situations. Ranchod, Androniko, & Modi, (2012) detail 4 case studies where MRI was used to diagnose specific posterior fossa abnormalities after having an US. This paper examines research done to examine the posterior fossa in prenatal brains with the use of US and fetal MRI. Literature…

Magnetic resonance imaging uses non-aggressive magnetic imaging technology to produce a three dimensional image of a bodily part. This is similar yet different to the use of x-ray imaging for similar purposes, however, MRI has no trace of the damaging ionizing radiation given off during the use of x-rays and CT scans. MRI is generally used for inspection and detection in the muscles, ligaments and soft tissue through the human body and can be used to monitor treatments, diagnosis of a patient…

the back office and preparing the patients before getting an MRI. Working in the front is a great job, but it is a means to an end for me. I need something more challenging, something that catches my interest and will keep me on my toes every day. Magnetic Resonance Imaging is what I want to do, as I started to research going to school and talking with my coworkers The Gurnick Academy is what caught my…

magnets. When the magnetic field makes the spinning protons wiggle, the stronger the magnetic field, the faster the wiggle. Nuclei wiggle at roughly 50 million times per second. If a proton is excited by some energy like a radio wave it will send that energy back as a radio signal that is slightly detectable. A MRI is basically a strong magnet, radio transmitter and receiver, as well as electronics to organize or coordinate their operation. The magnet creates the strong magnetic field, stronger…

location of eloquent areas adjacent to the tumor, which revolutionized DLGG approach. The most important techniques include functional MRI (fMRI), magnetoencephalography , white fiber tractography by Diffusion tension imaging (DTI) and transcranial magnetic stimulation. (41,48) fMRI is a noninvasive imaging modality that uses cortical blood flow changes as a tracer for increased or decreased neuronal activity, thus allowing cortical mapping when the patients perform specific tasks. One should…

The 100 is a novel written by Kass Morgan. Kass Morgan studied at Brown University to achieve her Bachelor’s degree for literature and then later got her Master’s degree at Oxford. She now lives in Brooklyn, New York. The 100 is her most successful novel written and she has been awarded many things for this novel. This novel takes place around 300 years after the Earth was exposed by radiation, which made the Earth not safe to be on. In the novel, humans are known as the “Colony”. This…

Answer Choice “D” is the best answer choice. This patient has findings on axial diffusion-weighted MRI, which show high signal activity in the cortex of the temporal lobes and insula, much more marked on the right. This finding is consistent with a diagnosis of herpes simplex encephalitis (HSVE). An MRI of the brain is the preferred imaging study in patients with suspected HSVE. Proton-density and T2 images may be more helpful than T1 images. An MRI can noninvasively establish many of the…

Brain scans are an important tool used by doctors to allow them to have a look at what might be doing on inside the brain giving a patient discomfort. Brain scans have a wide range of potential that has yet to be utilized by doctors. This type of imagery is only used when symptoms occur and once the issues have already arose. If a child received a brain scan as a baseline scan and then continued to receive a brain scan once every five years during their lifetime. It would be beneficial to both…
