The Pros And Cons Of Magnetic Resonance Imaging

1635 Words7 Pages

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. Other pros of MRI scanning are that it is non-invasive and gives precise imaging results. As with any exam with pros there are also cons. One disadvantage is that because of the strength of the magnet it is very important to screen …show more content…

Since the inception of MRI, it has not only progressed in the research area, but it has made great strides in the clinical areas. An exam that was first used to image the body in 1976 has advanced to now being used to measure brain chemistry and has the abilities to image and examine unborn fetuses. As discussed above MRI has many advantages. One such advantage is that there is no radiation dose to the patient during the exam. The advantages of MRI greatly outweigh the disadvantages of MRI. However, the concerns that MRI is very time consuming and very expensive are still present. With future improvements with MRI algorithms to help reduce scan times and the research of magnetized molecules to make it less expensive MRI will continue to grow and be accessible to more people. With the continuing success and future advancements of MRI scans the number of MRIs ordered and performed every year will continue to grow and in turn will save more patients’

Nuclear Medicine: Nt1310 Unit 9 Final Paper

933 Words | 4 Pages

1. Write a brief introduction about the diagnostic imaging modality. Nuclear medicine is a section of medical imaging that uses radioactive medication known as radiotracers or radiopharmaceutical (Understanding nuclear medicine, 2009). Radiotracers are given to the patient through injection, swallowing or inhalation, which makes the body radioactive for a short time. The radiation is detected by a special camera, and then the image is produced.

Computed Axial Tomography Analysis

The idea reckons on a fact that the susceptibility of different tissues could act as a contrast. Magnetic susceptibility of different tissues makes them go out of phase with each other thus helping in determining a signal from a particular tissue. SWI is three to six times sensitive than a T2* Gradient Echo MRI. A neuron is the basic unit of a nervous system. It has a cell body which is referred as soma, that comprise of nucleus and ribosomes that helps in protein synthesis.

The Pros And Cons Of Magnetic Resonance Imaging

164 Words | 1 Pages

Based on Westbrook et al. (2011), Magnetic Resonance Imaging (MRI) is the imaging modalities that has excellent soft tissue manipulation of the images compared to others. To detect pathologies within the body on MRI images, there must display contrast between normal anatomical characteristics and between anatomy and abnormality (Westbrook et al., 2011). In this assignment will get a look deeper into the image contrast of MRI.

The Pros And Cons Of MRI Scan

169 Words | 1 Pages

There are also huge risks that some people may also have to take when getting a MRI. If you are wearing any metal objects or have any metal implants in your body the magnetic fields produced by the scanner will detect and then attract them at great force. Although they are usually safe for pregnant women there are still some risks because the MRI scan can cause the body to heat up. As a safety measure most doctors will advise that you do not have a MRI scan in the first 3 months of your pregnancy unless it is considered critical. There is also an extremely rare risk of an allergic reaction occurring only about 1 in 10,000 people given gadolinium, however there is still the possibility.

The Pros And Cons Of Magnetic Resonance Imaging

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.

Medical Radiation Technologists Act To Justify Public Trust

1119 Words | 5 Pages

Essentially, optimization is based on the requirement of ALARA which stands for ‘As Low as Reasonably Acceptable’, where MRT’s must make sure that exposures are kept as low as possible to achieve an image with diagnostic quality (ICRP, 2007). This is further outlined in the ‘Radiation Safety Act 2016’ in section 9.1where, a health professional who deals with radiation must ensure that the benefits to people and society must outweigh the risk of harm to people (Radiation Safety Act, 2016). Both of these legislations illustrate the importance of radiation safety to the profession of medical imaging and thus MRT’s must abide by these standards to make sure they are holding the safety of the patients and the public to a high standard. This upholds trust and confidence as individual patients and the public can be confident that the care they receive during an x-ray procedure holds their best interest in

Alzheimer's Strengths And Weaknesses

PET scans produce images of inside the body which are 3D and enriched with detail. The scans direct our attention to the abnormal areas and allow us to see which parts of the body are working well and which parts aren’t. This is particularly useful as it can help doctors diagnose people with Alzheimer`s. The PET scanners work from radiation which is emitted from the substance radiotracer. The most typical radiotracer which is used is called flurodeoxyglucose, which isn’t that much of a shock to the body as it treats it like a natural glucose.

Although funds are being cut from Texas public schools, it has not kept the state of Texas from increasing the demands of standardized testing. Over the last several years, Texas public schools have chosen to sacrificed valuable classroom time, once designated for meaningful teaching and learning, in order to fulfill state-wide testing requirements. Due to increased pressures set by the state for each school to meet established score demands, students are spending a tremendous amount of classroom time preparing for high-stakes tests, instead of allowing students the opportunity to gain and improve upon critical thinking skills necessary to meet the challenges of everyday life. In order to redirect educational focus on preparing the youth for

Advantages Of Forensic Imaging

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
