In a quote from David Gerrold he says, “In the 20th century, we had a century where at the beginning of the century, most of the world was agricultural and industry was very primitive. At the end of that century, we had men in orbit, we had been to the moon, we had people with cell phones and colour televisions and the Internet and amazing medical technology of all kinds.” One of the many amazing medical technologies that we have today is an MRI (magnetic resonance image). MRI’s save millions of lives every year by getting us clear images of internal body structures so that we can diagnose and treat patients quickly.
Not all waves are the ones like in the ocean. For example there are radio waves. Radio waves are a type of electromagnetic radiation

The MRI machine looks like a long narrow tube with openings at both ends. At the opening of the tube, the patient lies down on a moveable table that slides in and out of the machine. A technologist monitors them from a different room which they can talk to through a microphone. However if the patient does happen to feel uncomfortable or have claustrophobia, then they can give medicine to feel sleepy or less anxious. In some cases, a contrast material, typically gadolinium, may be injected through an intravenous (IV) line into a vein in the patient’s hand or arm. The contrast material enhances the appearance of certain details. An MRI can last anywhere from 15 minutes to more than an hour. The patient must hold very still because movement can blur the resulting …show more content…

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
Next, we will discuss the problems identified in the case study. The first problem is design deficiency especially in the MRI room and on the oxygen tank. As explained previously, there is poor communication in the MRI room due to the absence of microphone to inform the technologist in the console room about the existing problem. The oxygen tank meanwhile did not have a proper indication panel that informs the state of the oxygen level in the tank. Design deficiency is a major problem because in a state of inadequacy, needed materials for the safety and optimal environment cannot be
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).

Magnetic resonance angiography (MRA), similar to CT, uses a magnetic field and pulses of radio wave energy to provide pictures of blood vessels inside the body. A dye is often used during the procedure to make blood vessels appear clearer. Lastly, a cerebral angiogram may be done. This is an x-ray test, where a catheter is inserted into a blood vessel, usually in the groin or arm, and moved from the vessel into the brain. A dye is also injected.
One of the greater advantages of fMRI is the spatial resolution (millimeters), so we can say MR imaging has outstanding spatial resolution but has a short coming with respect to temporal resolution of less than a second (4).
