Magnetic resonance imaging

Over the past two centuries, the medical field has grown, advanced and improved dramatically. From discovering new types of treatment and medicine, to using incredible technology to diagnose rare illnesses, scientists have come a long way in terms of research and diagnosis. One of the most significant discoveries was made by Nikola Tesla in 1882. 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 diagnose many illnesses and injuries, such as strokes, tumors, aneurysms, spinal cord injuries, multiple sclerosis and eye and inner ear problems. This machine is also a great tool for medical research, as it allows for images of many parts of the body to…

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…

In late 1980 's Seiji Ogawa discovered the blood-oxygen-level dependent (BOLD) contrast (Menon, Ogawa et al. 1995). BOLD rests on the idea that when neurons in certain part of the brain are active, it results in increased flow of blood in that area. This increased flow brings in Oxygenated Hemoglobin and reduces the amount of Deoxyhemoglobin within the capillaries. Thus we can state BOLD contrast occurs not because oxygenated hemoglobin increases the MR signal but because it displaces the…

risks to one’s health. However, if MRI suits are not properly designed nor operated correctly, MRI exams may result in building damages along with fatal 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…

I chose the topic MRIs. I will discuss the following topics, what an MRI is, what is an MRI used for, and How should you prepare for an MRI and the risks and benefits. Magnetic resonance imaging (MRI) is an examination that uses a magnetic field and three dimensional detailed anatomical images to take pictures of the inside of the body. In many cases, MRI gives different information about structures in the body that can be seen with an ultrasound, X-ray, or even a computed tomography scan or as…

The best imagining device that would be best to use to localize the tumor in the man’s brain is the MRI. This is because the MRI, which is also known as the Magnetic Resonance Imaging, is a scanner that uses a powerful magnet and radio waves linked to a computer to create remarkably clear and detailed cross sectional images of the body. The MRI machine can be used to view, monitor or diagnose various things. It can be used to identify and monitor abnormalities of the brain and spinal cord, and…

Magnetic resonance imaging, also known as an MRI scan, is a type of scan that uses magnetic fields and radio wave energy to create images of the organs and tissues, such as the brain. It is a scan that is used to detect things such as tumors, infections and injuries. It is often used after an x-ray or CT scan is done to gather more information. This paper will discuss MRI in depth such as how an MRI works, its use in society, the differences between MRI and other scans and the future for MRI. …

Magnetic Resonance Imaging (MRI) is a medical technology that uses magnetic fields to interact with protons in the human body, producing an image that allows doctors to diagnose disease and/or injuries (DiGiuseppe, Haberer, Salciccioli, Sanader, & Vavitsas, 2012). The idea of MRI technology had come from Raymond Damadian who was a medical professor and had founded the company that manufactured MRI scanners (Bergman PH. D, 2015). In the beginning, Damadian had been using Nuclear Magnetic…

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 increased use of Magnetic Resonance Imaging (MRI) has contributed to the rising cost of imaging expenses. The availability of technology, the increased demand for patients and doctor, and advanced technology are factors that have contributed to the increase. Hypothesis: The increased use and availability in MRI imaging has increased the cost in MRI imaging procedures by approximately 33 percent from 2011 to 2013. In an attempt to identify the connection between increased use of MRI…
