Magnetic resonance imaging Essays

Magnetic resonance imaging (MRI) or Nuclear magnetic resonance imaging (NMR) is a non-ionizing imaging modality used for clinical imaging over the past 25-30 years. This imaging modality provides excellent soft tissue imaging with good contrast resolution in different parts of the body like brain, muscles etc compared to other ionizing modalities like CT (Computed tomography) and conventional radiography. The most important advantage of MRI compared to other imaging modalities is the fact it uses

Topic: Magnetic resonance imaging Introduction: Nuclear magnetic resonance which is nuclei absorb and re-emit electromagnetic radiation phenomenon under a magnetic field. Actually, all elements’ nuclei are electrically charged and spin with different energy level to behave like a magnet. When it is at lower energy which will generate a magnetic field in the direction of the external magnetic field and opposite direction with spin at higher energy. The energy difference between them will correspond

hope for parents of teenagers that feel like their child is a lost cause. In a 2015 issue of Scientific American titled The Amazing Teen Brain, author Jay N. Giedd explains why the teenage brain is not “biology gone wrong”. With the help of magnetic resonance imaging (MRI) the brain of people of different ages can be studied to provide more accurate information. One of those findings is that the adolescent brain does not mature by getting larger, that it matures by having its structures more interconnected

A genetic disorder is an anomaly in the DNA that leads to a unique trait being present in an individual. They are caused by mutations in the genes and are extremely rare in most cases. Poland Anomaly, a rare genetic disorder, is responsible for the underdevelopment or lack of a left or right pectoral muscle (National Human Genome Research Institute). Exact statistics regarding the rarity of the disorder are difficult to acquire because it is thought to be underreported and underdiagnosed. As many

In order to diagnosis of painful hydronephrosis in hospital, computed tomography (CT) scans is better than more-often-used ultrasound examinations, according to a clinical study conducted in few medical centers. Computed tomography and ultrasound are most usable modalities that commonly able to demonstrate both directly and indirectly of dilated ureter or known as hydronephrosis. (Jeffrey 2014) . Generally, excessive water consuming may cause gradual renal accumulation of fluids, resulting in hydronephrosis

Leadership is critical to advancing the nursing profession. All levels of an organization require strong nursing leader-

1972 by British engineer Godfrey Hounsfield of EMI Laboratories and South African physicist Allan Cormack of Tufts University, the first clinical CT scanners were installed between 1974 and 1976. The original CT scanners were only dedicated to head imaging at first until 1976 when larger, whole body systems became available. Compared to modern- day multi slice CT scanners which can collect up to 4 slices of data in about 350 ms and reconstruct a 512 x 512-matrix image from millions of data points in

There is only one approach in psychology that studies thoughts, feelings and behaviour. The biological approach believes that the way we are is due to our genetics and physiology. They believe that the activity going on our nervous system’s is what affects the way we think, feel and behave (Sammons, 2009). The physiology in the biological approach looks into how the brain functions. The brain is a very complicated machine as such, the brain is what controls our every move, every feeling and every

Corinne Kamrar fMRI 204566178 Whether or not neuroimaging, more specifically functional magnetic resonance imaging (fMRI), informs cognitive theories is investigated through two opposing views. Max Coltheart argues, cognitive neuroimaging lacks the ability to inform cognitive theory and therefore does not contribute to the study of cognition. In other words, cognitive theory informs neuroimaging and not the other way around, such that, neuroimaging informs cognitive theory. Contradicting Coltheart’s

Is it true that music can help you through many different situations? Well, it is commonly said that music is a very meaningful part of human cultures because it is an alternative way of communication. The impact of music in life is very remarkable through the history of the world, and according to scientists, music has influenced people since its creation because there is a theory about music, and it says that music gets people to act together and coordinated. Music seems to have an extended past

In this essay I will present and analyse my personal development and achievements along with the challenges I was faced with, in the four domains of clinical care, that were the result of applying the theoretical knowledge and practical skills acquired in the last two years of this course into clinical practice. Additionally, I will be providing an example for each of the four domains in the appendix section, in order to better demonstrate these points. Finally, I will conclude this essay with a

Introduction The course NURS 4102 Coordinating Nursing Practice offers a chance for me to learn how to corporate and apply nursing theories and knowledge learnt into real nursing practice. A variety of useful and practical knowledge for nursing practice were delivered by different lecturers and guest speakers. For example the leadership and management skills, theories and application in nursing and also resource, risk and crisis management in daily nursing practice. These knowledge prepared professional

Abstract Patients have a right to receive the best treatment possible in medical settings around the world. Sometimes a patient can refuse that treatment and as nurses we have to stand by and let that happen. Despite the fact that informed consent is not always directly obtained by a nurse, we still have a duty to assist the physician and patient in order to make the process as fluid and smooth as possible. One of the best interventions we can implement is guide a patient by educating them so that

Abstract— Brain hemorrhage is a type of stroke, which occurs due to artery bursting in the brain, causing bleeding in the surrounded tissues. Diagnosing brain hemorrhage, which is mainly through the examination of a CT scan enables the accurate prediction of disease and the extraction of reliable and robust measurement for patients in order to describe the morphological changes in the brain as the recovery progresses. The aim of this project is to help radiologist as well as medical students in diagnosis

Reflection, what is it? By David Mulcahy. (14375771) The Term reflection can have many meanings to many people. Reflection can carry meanings that range from the idea of professionals engaging in solitary introspection to that of engaging in deep meaningful conversations with others. But for this assignment I will focus on; what is refection in the clinical setting, why it is important for health care professionals to reflect and where the ideology of reflection came from. I will also provide a

Hockey is more dangerous and intense than football Hockey is ranked 9th in most popular and challenging sports but football is not seen in the ranking. Hockey is more challenging and more physical than football, which is why its ranked 9th. Though football has many head injuries hockey has many other injuries involved with it as well. Playing hockey takes lots of skill, intensity, and its more physical. First, Hockey is more dangerous than football because of the injuries. In hockey injuries

Developing Perspective in the Art of Caring: Nursing Philosophy Caring for others is self-less and compassionate. By caring for others, we put ourselves in the same position as the patient. Nursing encompasses caring for others. However, the art of caring is not practiced the same by all nurses. Practicing nursing compasses following rules but one can use theories to care. There are many approaches to nursing, and there is not necessarily a bad or good one. My belief is that people can adapt and

In the case of meningiomas, the tumor origin can be found anywhere along the surface of the dura. A general rule is that the neuraxis is displaced to the side opposite to the tumor origin. Therefore, posterior meningiomas put pressure on the spinal cord anteriorly and for this reason are better approached directly with a laminectomy. Posterolateral and lateral meningiomas displace the neuraxis anteromedially and medially, respectively. A posterolateral approach is advocated, by laminectomy possibly

Tectal plate gliomas are low-grade, benign neoplastic lesions arising predominately in children. The tumor comprises 10-20% of all brain tumors in the pediatric population. They are of neural crest embryological origin and develop from glial cells in the brainstem. This form of astrocytoma is usually spontaneous, with no known associated environmental or genetics risk factors. However, an association between Neurofibromatosis Type 1 and brain stem gliomas have been found. Symptoms are non-specific

difficult to determine accurately. Due to its design, metallofullerenes are more stable than normal empty fullerenes up to very high temperatures and have uses in medicine. A metallofullerene with gadolinium is used as a contrast agent in magnetic resonance imaging scans and other metallofullerenes may be able to transport radioactive ions to cancerous tissue, providing a
