Magnetic resonance imaging

Numerous studies have been conducted on MRI being a useful tool in prenatal imaging of the posterior fossa. Gurbaud (2004) suggests that MRI is useful as a complementary investigation to US in three particular situations. Ranchod, Androniko, & Modi, (2012) detail 4 case studies where MRI was used to diagnose specific posterior fossa abnormalities after having an US. This paper examines research done to examine the posterior fossa in prenatal brains with the use of US and fetal MRI. Literature…

Brain scans are an important tool used by doctors to allow them to have a look at what might be doing on inside the brain giving a patient discomfort. Brain scans have a wide range of potential that has yet to be utilized by doctors. This type of imagery is only used when symptoms occur and once the issues have already arose. If a child received a brain scan as a baseline scan and then continued to receive a brain scan once every five years during their lifetime. It would be beneficial to both…

Ultrasound sonography is used in almost every field of medicine practiced today. It is a very important tool in diagnosing several possibly deadly illness. Ultrasound sonography may be the best option in certain situations while other options may not even be a first option. But, as with anything there are certain risk factors that need to be taken into consideration. There are pros and cons to almost everything, however this essay should show you how the pros outway the cons. The field of…

X-rays is one type of electromagnetic radiation that can send waves through the body which makes us see through the body tissue but it doesn’t go through the bone. Therefore it is used in hospitals to see if a person has a broken bone or any diseases. Because it can go through clothes and the human skin it is also used in airports to see if anybody has a knife or anything dangerous with them. X-rays were first discovered by German scientist Wilhelm Conrad Roentgen in 1985. Roentgen found x-rays…

For my three health careers I chose radiologist, pediatric oncologist and athletic trainer. I do not necessarily want to go in the medical field, but if I were to I would want to work in one of these three careers. All three jobs require skills, reasoning and intuitive thinking. You might find yourself in a situation that demands fast thinking and problem solving, so you need to be prepared. The first career I chose was a radiologist. To become a radiologist you must obtain a Bachelor's Degree…

discussing how Medical Imaging uses wave behavior, why it is needed, and how it captures information and energy. I will also be explaining the differences between the types of Medical Imaging and how the MRI Scan is used in the medical field today. Understanding Medical Imaging Medical Imaging has several different technologies that are used to view the human body. There are different types of Medical Imaging such as MRI, X-ray, CT, ultrasound, mammography, molecular imaging, and Pet Scan.…

Numerous articles support either modality. The research will be based on the analysis of the different articles and criticising the validity of each argument. They both share similarities in the patient preparation. CT colonography as well as barium enema require bowel preparation, the bowel need to be free from any faeces as its presence can mimic pathology and impair diagnosis. CT colonography offers cross sectional images and allows three dimensional reconstruction. This feature results in…

the medical field. Nuclear energy in medicine has been discovered more than 50 years ago and it has been widely-used ever since. The first use of nuclear energy in the medical field is for medical imaging which is a way of creating visual representation of what is going on in our body. Medical imaging began when Wilhem Rontgen discovered x-ray in 1895. However, at that time, the dangers of radiation was not known yet. Fast forward about 20 years later, contrast agents which are harmless to the…

Lasik surgery is the most common type of refractive surgery. The aimed result of the surgery is to refract light rays on the retina without damaging the surrounding cellular cells. Lasik surgery is a procedure that was developed to correct the vision problems of Nearsightedness, Long-sightedness and Astigmatism. Nearsightedness (myopia) is when you can see nearby objects clearly, but distant objects seem blurry. Long-sightedness (hyperopia) is when you can see distant objects clearly, but nearby…

Chapter Three - Conclusions 3.1 Conclusions This research aimed to verify the synthesis protocol for HPA-12 and analogues from aldehydes of Greatrex et al. (2014). Limited success in synthesising required quantities had a negative impact on the outcomes of this research, and no reasons were identified for the low yields that were obtained. Additional time, or resolution of issues resulting in low yields, would have allowed additional research and confirmation of the synthesis protocol. Long…
