Saint John’s College Junior College Abstract
MRI is ranked as one of the most rapidly advancing diagnostic imaging techniques used today. Though it is at the top, the hazards of it must be acknowledged, accepted and respected. The procedure itself is safe, but if there is a chance that it might go wrong, then it can go really wrong. Hence it is valuable to know the safety issues considered by radiologist, clinicians, physicians and radiographers during examination. This paper reviews the history behind the birth of MRI with Felix Bloch and Edward Purcell; a few uses of MRI in the medical field; the advantages with its preciseness and accuracy and the disadvantages of this application with patients containing metallic devices within them. …show more content…

Using an MRI which is painless has the advantage of avoiding exposure to X-Ray radiation. Another advantage of MRI is the preciseness and exactness in detecting the structural abnormalities or deformity of the body. Like the ups and the good in life there is also the down and bad of all times. Disadvantages of MRI scans can befall to patients who have metallic materials within the body. Therefore, patients who has such elements within their body must give inform to their doctor prior to the examination. Any metallic materials such as surgical clips, artificial joints, bone plates, or prosthetic devices etc. can affect the imagery obtained significantly. Patients who have had any insertion heart pacemakers or any metallic implants in their body must not go through an MRI scan because of the high risk of the magnet moving the metal in the areas these devices or metallic plates are located. According to the database of the U.S. Food and Drug Administration (FDA) and Medical Device Reporting (MDR), several incidents involving MRI have been reported where one of it was as

Too much exposure to ionizing radiation can damage the tissues. Children, young women and fetus are more sensitive to this type of radiation than others (Fahey, 2012). • Maintaining the Highest Level of Safety with NM Workers in nuclear medicine should follow safety rules. While working with radioactive materials, personal protective equipment like gloves, protective eye wear and cloths and in some cases fume hoods must be used. NM procedures must be practiced in special closed places.

Ever since the discovery of the intriguing Roentgen ray, physicians and radiographers have thrown themselves into harm’s way for the benefit of patients and the field. Walter Dodd, M.D., was no less noble in his investments to his radiography career. As soon as Dodd heard about the discovery of the Roentgen ray, he committed himself to experimenting with the newfound science. In 1896, Dodd constructed an x-ray machine at the American Hospital. Not long after, he began suffering from the unprotected radiation exposure.

Ultrasound does not go through bone and clear image of some part of the body can not produced for instance brain which is surrounded by bones. Although ultrasound is a safe technique and it doesn't use ionising radiation, but it has some limitation for example ultrasound is not useful for examining the structures that has gas on them. Another risk related to ultrasound is

Magnetic Resonance Imaging (MRI) is a medical exam used to image the body to help screen, diagnose, measure the success of medical treatments, and view the function of some organs. MRI uses a magnetic field, radio waves, and hydrogen nuclei within the human body to produce images. MRI does not use radiation to acquire images as many of the other imaging modalities do. Not using radiation is a benefit of MRI since radiation is cumulative, and there are always concerns of radiation induced cancers if used repeatedly as needed for things such as follow ups. No radiation also makes MRI safer for children and expectant mothers.

While x-rays are generally used to see the denser structure in the body, for example, bone, ultrasound is utilized to analyze the soft tissue. The primary disadvantages of ultrasound is that hypersthenic patients are harder to picture because of assimilation of sound waves. Likewise, gas, air and bone additionally cloud critical structures. There is no positive reaction because of the absence of ionizing radiation, making it alright for pediatrics and adults. In obstetric exams, it is used to visualize the baby, cervix, placenta, and uterus.

There are a number of ways that brain activity can be measured and viewed, these vary from Magnetic Resonance Imaging (MRI) to lesion studies, each one having their own advantages and disadvantages. A lesion study can be construed as a method of the neuropsychologist to study the behaviour that is altered by the selected removal of one or more of the brain’s components (Gazzaniga et al., 2008, p.125). This method of study implements a unique insight into how the human brain generates emotion and feeling through electrical impulses (Feinstein, 2013, p.304). Gazzaniga et al (2008) do point out that one of the major impediments of a lesion study is that humans cannot be subjected to brain lesions as an experimental procedure.

Ultrasound can be a safe process if the technician follows the rules and regulations of all the possible factors that could make the imaging risky. Since regulations can help decrease the risks of ultrasound action is being taken in some states “by creating regulations to control the distribution and use of ultrasound technology” (Alexander 30). With the help of states making regulations for the levels and frequencies of scanning, ultrasound can continue to be one of the safest imaging processes in the medical

An MRT should not collect or discuss sensitive patient information in public areas where they may be overheard. This means that details apart from the patient’s name should not be discussed in the waiting room and should instead take place in the X-ray room. Furthermore, when collecting this information, the MRT should only ask for information that is needed for their scope of practice. This is further outlined by the Privacy Act 1993. In section 6.4 clause (b) it is stated that “personal information must not be collected by an agency by means that are unfair or intrude to an unreasonable extent upon the personal affairs of the individual concerned” (Privacy Act, 1993).

Radiomics lies at the juncture of what I believe to be extremely exciting science in the coming future of personalized medicine. This is what prompted me to approach Dr. Rivka Colen (desired mentor), of the Department of Diagnostic Radiology, to conduct research in her lab. An interplay between research and clinical treatment such as the way Dr. Colen implements will be one of the grounds that I intend to structure my own practice around. The MD Anderson 1st Year Medical Student Program would help me achieve the first steps towards conducting research in my career as a physician-scientist.

As it has already been discussed in this paper, physicians are responsible for any clinical negligence that may cause harm or injury to the patient. In many journal studies researching radiology, various field cases have been identified and studied. They have shown that radiologists who have not been very often accused of clinical negligence have become in trouble. The errors committed while conducting their radiological work are sometimes caused by their lack of experience or out of their care. But in both cases, they are held to be liable and patients may file lawsuits against

An MRI machine does not use X-rays to make photos. MRI scans take much longer time t produce a detailed photo and is a lot more noisy than CT scans. Another difference between MRI scans and CT scans is that CT scans are suitable for bone injuries, lung and chest imagining and cancer detection. While MRI scans are suitable for soft tissue evaluation, e.g., ligament and tendon injury, spinal cord injury, brain tumors, etc.

Some advantages of this technique are that there is no radiation involved, it is good at visualizing soft tissue, and that since it can visualize soft tissue so easily it can identify a multitude of different problems. Some disadvantages are that it is time consuming, expensive, and there is extensive training needed to operate it. The last type of imaging technique that will be covered is conventional radiography which can detect foreign bodies and changes or lesions of the skeletal system and is used when the corpse cannot fit into the CT machine. The advantages of this technique are that it is simple, quick, and cost efficient. However, it uses radiation, cannot make three-dimensional reconstructions, has a superimposed image, and it cannot visualize soft tissue
