Earth's magnetic field

It so happens, once in a few decades, that an invention comes along to change the shape of the world. We’re fortunate that the trend has continued in the field of medicine, as the integration of technology with traditional practice has changed the future of medicinal science. However, of all the things that have shaped up the future of medicine, the one that stands out as perhaps the most important of them all, is MRI. In this article, we discuss all you want to know about MRI, an MRI scan, the…

I is a great tool for medical imaging and widely used for MS, but it has some limitations in lacking specificity and MRI not capturing diffuse white matter pathology 1. New emerging techniques such as transcranial magnetic stimulation (TMS) and optical coherence tomography (OCT) for monitoring visual impairment by MS have the potential to address issues not resolved by current MRI techniques. TMS is a new method not widely used yet, but suitable to detect the conditions affecting MS patients.…

accidents to patients. This is due to the extremely strong magnetic field, foreign bodies containing metal are strongly attracted to the magnet, and the improper use of the equipment. Magnetic Resonance Imaging (MRI) is a popular machine used to image the human anatomy in multiple cross sectional slices. Unlike Computed Tomography, MRI machines do not use any ionizing radiation to develop these images. However, an extremely strong magnetic field and with radio waves are used instead. While…

Three words, Magnetic Resonance Imaging. It’s the MRI, truly a miracle machine! The MRI has helped people in the past, is helping people in the present, and will help people in the future. Inside is high tech machinery that has both mechanically, and has chemically powerful equipment. The inventor is remarkably intelligent, as well as his invention. Both his religious and medical beliefs played a role in the creation. Question is, how did all this come to be? As a break though in the 20th…

1. Meningioma: (p. 116) a tumor, usually benign, arising from the meningeal (arachnoid, dura matter, pia matter) tissue of the brain. Carcinoma: (p. 116) a cancer arising in the epithelial tissue of the skin or of the lining of the internal organs. Phenomenology: (p. 118) the science of phenomena. This is an approach that concentrates on the study of consciousness and the objects of direct experience. 2. Chapter 8 describes the case of Mrs. S who suffered a stroke in her right cerebra…

What are the different types of adult brain tumors and how are they caused? How are brain tumors treated? Brain tumors are treated by surgery or chemotherapy. Surgery is a very common treatment for primary brain tumors.Sometimes it takes a lot of time to fully take out a brain tumor because not all tumors can be fully removed. Which means that a surgeon will have to attempt to reduce the tumor’s size. How are brain tumors caused? Brain tumors are caused by some genetic diseases which put you…

In the film, Elf, Buddy, a human raised by elves, never quite “fits in” with those around him. As he leaves the North Pole in search of his father, he acts in a rather distinct manner. Thus, in Elf, as directed by Jon Favreau, Buddy’s interactions with others and his surroundings highlight his unique identity. Being a human in the elf-dominated world, Buddy undoubtedly stuck out physically. He was several feet taller, he was heavier, and he struggled to cope in the petite elvish world,…

The field of neuroscience has come a long way from the physical study of the brain by way of dissecting the deceased or experimenting on live animals, to today’s age where one could see the brain in real-time via functional magnetic resonance imaging (fMRI). The fMRI is a noninvasive technique that provides images that detects the changes in blood flow that in parts of the brain that are more active than others. The information can then be compared to existing anatomical knowledge of the brain…

any other cells in the body, when neurons are activated they consume glucose and oxygen to fuel their activity and they produce metabolic waste. According to Sadock, Sadock, and Ruiz (2015), a functional magnetic resonance imaging (fMRI) device works from this principal by using high magnetic fields and radio frequencies to indicate activity. The fMRI helps the medical professional to peer into brain activity, not by measuring brain activity directly, but by observing the flux of oxygen…

though the cause-effect relationship may not be able to be established because of the complexity of the structure of the brain. There are different types of brain-imaging technologies. For example, the PET(positron emission topography), the MRI(magnetic…
