Hearing the beeping and creaking noise of the machine, as the patient slowly rolls inside, is an everyday routine. As the patient sits inside, quietly panicking from claustrophobia, the patient’s body is scanned, hears reassuring words about how they are doing great and to stay still over the microphone. A twelve-year-old boy named Chase, had just recently fallen out of a tree and broke a few bones in his arm and collarbone. The Radiologist of the facility, Dr. Anderson M.D, instructs to scan the entire body just to make sure nothing else was sprained or broken as the boy’s body was covered in a few scrapes and bruises. As his body was being scanned, the MRI Tech and Chase start to ask each other questions to calm down his nerves and distract him from …show more content…
Anderson. This is an everyday process. As an MRI Technologist, only the radiologist of the facility can diagnose the patient. The same, everyday routine is the job of an MRI Technologist. There may be times when an emergency will pop up but that’s mainly for hospitals and the emergency rooms. An MRI Technologist aids in locating potential problematic medical conditions.
One of the important factors in this field is the MRI machine. MRI stands for Magnetic Resonance Imaging. The MRI machine is a large, strong magnet. The magnetic fields line up
with certain atomic nuclei in the body and scans your organs (“Guide to Becoming an MRI Technician or Radiographer.” InnerBody). While the patient lies in the magnet, there is a radio wave used to send signals to the body and receive them back. The returning signals are created into images and then printed out to send to the doctor. There are 3 different types of machines at the Millennium Imaging facility. The first machine is the 1.0 Tesla. This is the weakest out of the three. This machine is mid-field strength and is very minor. The next machine is the 1.5 Tesla. This machine is
My interest in MRI started when I first read the book “MRI, The Basics” written by the author Ray Hashemi. By the time I successfully finished my MRI clinical placement in Tehran University of Medical Sciences, I knew for sure that MRI would be the field I would be choosing to take on. What attracts me most about MRI is how beautifully scientist could create a technology that can take advantage of the magnetic moments of human body for imaging it without any harms of ionizing radiation. Although there are drawbacks to MRI, combining it with other modalities would be a more effective approach to an accurate diagnosis.
The MRI, on the other hand is less expensive and much safer (as it doesn’t expose the patient to potentially harmful radioactive chemicals). The MRI or magnetic resonance imaging device, as an safer alternative, applies a powerful magnetic field around the head of the patient.
After graduating with my Bachelor’s degree, I continued to work as a staff MRI technologist. Even though I loved what I did and had a passion helping people, the lack of diversity within radiology and its limited room for growth bothered me. I decided to look into furthering my career and found an interest in Health Information Technology. Upon researching many different schools through the country offering an online graduate Health Information Technology program, the University of Michigan in Dearborn stood out to me. Medicine and technology have both always been a part of my life, and I am very happy and excited that the chance for it to play a new part has finally arrived. I’m motivated to learn how I can combine the science of information with clinical knowledge so I can help to better patient care and
Magnetic resonance imaging (MRI) is considered as one of the pioneers in medical imaging for diagnosis of pathologies involving soft tissues and internal structures. MRI provides good contrast resolution between different soft tissues of the body especially in brain, muscles, heart etc compared to other medical imaging modalities like computed tomograpgy (CT) and conventional radiography which utilizes x-rays for imaging. The other important aspect of MRI versus other imaging modalities like CT and conventional radiography is that MRI uses no ionizing radiation like x-rays for imaging, instead it uses a strong magnetic field to align the magnetization of some atoms within the body , then uses radiofrequency pulses to systematically alter the alignment of this magnetization. This process causes the nuclei of certain atoms to produce a magnetic field which can be detected by the scanner, and all this information is used to reconstruct an MR image of the scanned area of the body. The initial experiments by Sir Otto Stern in the year 1922 stated that physically the magnetic resonance ima...
I choose this article “What is MRI? How does MRI work” by Mathew Kalapurayil because I found these devices to be interesting and also extremely useful to healthcare providers because the vast number of patients saved by a scan which could detect and diagnose diseases, without any physical harm or side effects. The advantages of MRI scan include its careful precision in noticing physical irregularities of the body. In medical technology, identifying the disease is not based only on one result rather it is a collection of information shared by a group of specialists; one example of this is the radiologists who are skilled doctor. The radiologist is trained expert who understand and interpret the MRI information. His job is to read the magnetic resonance image from your scan and submit the result to your doctor. Your physician will then share this information and other medical information associated with your case with you. MRI stands for Magnetic Resonance imaging ((Kalapurayil, 2013).
One of the most recently new advances in radiology is the use of magnetic resonance imaging (MRI). MRI has been around for the past century. It was at first called Nuclear Magnetic Resonance (NMR) and then it changed to MRI once there was an available image. Walter Gerlach and Otto Stern were the first scientists to start experimenting with the magnetic imaging. Their very first experiment was looking at the magnetic moments of silver by using some type of x-ray beam. The scientists then discovered this was by realizing that the magnetic force in the equipment and in the object itself. In 1975, the first image was finally created using and MRI machine. The scientists used a Fourier Transformation machine to reconstruct images into 2D. The first images ever use diagnostically was in 1980. This is when hospitals began to use them. At first the images took hours to develop and were only used on the patients that needed it most. Even though MRI has been around for a long time, it has advanced and has been one of the best imaging modalities recently (Geva, 2006).
The 3D mammography is said to reduce the inaccuracy of breast cancer tests. The magnetic resonance imaging (MRI) is among the major competitors of the 3D mammograms. The MRI utilizes radio waves as well as strong magnets as opposed to the 3D mammography which use x-ray. The radio wave energy is usually absorbed and formed into unique patterns depending on the body tissues and disease. A computer then translates the patterns into specific readable images. A contrast liquid, gadolinium, is injected into the veins of the patient during or prior to the
MRI uses magnetic fields and radio waves instead of radiation to measure the relative water content in tissues. The very strong magnetic field cause hydrogen protons in water to position themselves in line with the direction of the magnetic field, which is large enough to provide a strong imaging signal. The radio waves (and some weaker magnetic fields) are then used to displace the protons, so that when these radio waves stop, the protons return to a fixed position. When the protons relax and return to the lined position, they resonate signals that are transmitted to a computer. This relaxation time is measured in different ways depending on which scan is being used, and the computer translates that measurement into cross-sectional images of water in tissue. This is extremely helpful in diagnosing MS because myelin is a fatty substance that repels water, and in the areas where myelin has been damaged by MS (lesions), that fatty layer is gone—allowing those areas to obtain more water. Using what is called a “contract dye” allows the detection of lesions that are active or inactive throughout the
Magnetic Resonance Imaging (MRI) has been around since the 1930s. An MRI machine has a great purpose in the medical field. It is a radiology technique that uses magnetism, radio waves, and a computer to produce images of body structures, such as a patient’s head, chest, blood vessels, bones and joints, and much more. MRI machines help doctors figure out what is wrong with their patient's bodies. It allows doctors to take a closer look at a certain location and see things that other machines cannot see. By using this machine, it helps doctors figure out the problem faster and allows them to try and find a treatment or a cure.
In 1971, scientists were motivated to use magnetic resonance for detection of diseases after discovering the difference in nuclear magnetic relaxation times of tissues and tumors (Dr. J. Hornak, n.d). In 1973, Lauterbur and Mansfield defined the use of magnetic field gradients for spatial localization of NMR signals, laying the foundation for MRI in the future. Two years later, Richard Ernst used Fourier Transform (an algorithm for the analysis of heat transfer between solid bodies) to encode and reconstruct 2D images, which underpins MRI today (Geva, 2006).
CT scans and MRIs, or are incorporated into them in a different way for a clearer picture of what is
Now with the dangerous jobs in the world and even the dangerous playgrounds, electronic imaging is needed. Electronic imaging, an outstanding technological advancement, helps views bones, organs, and cancerous cells within the body. X-ray or radiograph was the first type of electronic imaging introduced into the medical field. This played an important part in the medical field because it allowed doctors to see broken bones and inflammation inside of organs. Another important electronic imaging that was introduce was the MRI. Magnetic resonance imaging (MRI) aids physicians in seeing soft tissues in the body. With the help of MRIs doctors are able to see whether those tissues are normal or damaged. A little later on functional MRIs were created to see the soft tissues function. Functional MRIs are commonly u...

Three simple letters such as “MRI”, may leave one in question of what it’s about. But MRI stands for Magnetic Resonance Imaging. In other words, an elaborated scientific form of a x-ray. It derives from Nuclear Magnetic Resonance Spectroscopy (NMR). NMR is enabling us to identify the structure of an organic molecule, but can also be applied to the imaging of the whole body organs, to what we know as an MRI. Spectroscopy is just a technique for analyzing the structure for a molecule based off how they absorb electromagnetic radiation. MRIs are one of the most powerful tools in medical diagnosis.
I chose this topic because I a found it as a very interesting thing which I wanted to know more about. I have been CT-scanned when I had concussion after a car accident when I was seven. Also because my father has been under a CT-scanner and a lot of my friends.
