Earth's magnetic field

every human function there is a physical correlate in the brain. Each scanner is unique to specific cases and has its advantages and disadvantages. This essay will discuss these different imageing technologies and how they have contributed to the field of neuroscience. Unlike an EEG (electroencephalogram), a PET scan allows scientists to view the physical brain, as…

The development of the MRI (Magnetic Resonance Image) machine has changed the medical world for the better. One of the first points about the MRI is that it was created by Professor Raymond Damadian in 1977. The first time the MRI machine was used, it took a total of five hours to do the whole scan. Also, the first MRI machine ever used is now in the Smithsonian Institute, and was nicknamed the “Indomitable.” Many people think they know what an MRI machine does, but most of the time they are…

specific disease. Usually, this technique includes the imaging process to detect and then treat according to the specific disease. In the reference of the medical theory, the radiology is a field that interprets and medicates the diseases utilizing the imaging technologies, such as X-ray, ultrasound, MRI (magnetic resonance imaging), computed tomography (CT), nuclear medicine, mammograms, and positron emission tomography (PET) to view the internal organs of the human body and identify the…

Have you ever wondered what the point of sleep was? Or, how we dream? A lot of scientists have researched and tried to determine why we sleep, but a true answer has never been concluded, but a strong theory has stated that us as humans may have evolved from animals that would sleep to put their body in a resting state, to keep them away from harm and to keep their body at a well-rounded temperature throughout the night. All mammals sleep, including marine animals such a platypus and a whale.…

Computed tomography (CT) scanning technology was discovered in 1972 and revolutionized the world of neuroimaging (Sadock, Sadock, & Ruiz, 2014). The CT scan was the first technique to allow the imaging of brain tissue in living patients (Sadock, Sadock, & Ruiz, 2014). During a CT scan, a patient lies on a flat surface, which incrementally moves through what is referred to as a gantry (Sadock, Sadock, & Ruiz, 2014). A gantry is a round shaped structure that contains a motorized x-ray source…

identify and study an individual’s brain function, thus indicating how these techniques help to understand how the brain works, some of these techniques include: Positron Emission Tomography (PET), Computed Tomographic (CT), Functional Magnetic Resonance Imaging (fMRI), Magnetic resonance imaging (MRI), Magnetoencephalography (MEG). This essay will discuss these techniques in detail, in order to attempt to determine how much certain neuroscientific techniques have contributed to the…

Elfuclana has a unique and interesting history compared to other countries. It is located 132 miles east of the coast of Ellis Island. The founding of this country all began with the Revolution of the Elves, also called The Elfolutionary War. It dates back to December 24th, 2076. It was the day before Christmas in 2076. Santa is, and has always been, the communist dictator of the North Pole. The elves have had to put up with his cruel ruling for long enough. One elf, named Tasol Elfuclan,…

MRI stands for Magnetic Resonance Imaging. Dictionary.com defines it as a noninvasive diagnostic procedure employing an MR scanner to obtain detailed sectional images of the internal structure of the body. From my own prior knowledge, Magnetic Resonance Imaging is a technique that uses a magnetic field and radio waves to create detailed images of the organs and tissues within the human body. The idea for Magnetic Resonance Imaging was initially conceived by Damadian in 1971 after he recognized…

An MRI scanner or a magnetic resonance imaging is a common apparatus used within hospitals which uses a scanning technique to show detailed images of the inside of a human body. There are two ways which an MRI scanner takes images of the human body. The two ways are the use of a strong magnetic field and the use of radio waves. There are two ways which MRI scanners work and the first is by hydrogen atoms. How this links within the human body is by the main link of hydrogen protons which are…

Diagnostic testing for the patient with acute appendicitis included magnetic resonance imaging (MRI) and a Karl Storz image of the appendix. An MRI is a non-invasive technique in which the patient is placed in a magnetic field to examine their body anatomy (Pagana & Pagana, 2014). This form of diagnostic testing provides healthcare professionals with imaging on a specific area of the body with the ability to differentiate between blood vessels, necrotic, and healthy tissue (Pagana & Pagana,…
