The benefit verses the effect of fetal Magnetic Resonance Imaging has been a controversially subject for years. Magnetic Resonance Imaging is a helpful tool for diagnosis of many diseases and abnormalities, but is it actually harmful to the fetus? Do the benefits of the Magnetic Resonance Imaging imaging outweigh the risks? Ultrasound is the mostly commonly used imaging used in pregnancy, but in certain cases using fetal Magnetic Resonance Imaging in conjunction with ultrasound is very beneficial in planning and strategizing care for the fetus. Magnetic Resonance Imaging has been proven to help to better characterize mass, show location and extension of the lesion, and to show more detail in certain conditions. Using MRI can help to characterize …show more content…
This is helpful for the doctors to get a better idea of what type of treatment plan they should formulate if it is a mass rather than a shadowing of a bone. Many times the pelvis bone can overshadow and appear as an abnormal mass rather than a bone. On the subsequent fetal MRI examination, the mass is not only better characterized, but is clearly idefined as entirely extra-pelvic. MRI helps in eliminating uncertainty from the ultrasound caused by acoustic shadowing due to fetal pelvic bones. Mass content is also of prognostic importance and is better delineated on MR.1 MRI is also helpful in determining lesions of the lungs and how large or severe they may be before the baby is born. Not only can the MRI determine the size of the lesions, but it can also determine the lung volume of the fetus. In fetal life, US is the most important, and usually the only modality required for lesion characterization and for identification of …show more content…
MR imaging at 1.5 T or lower magnetic field strength has been used to evaluate diseases in pregnancy for over 20 years without any documented harmful effects. Magnetic resonance imaging (MRI) has been shown to be useful in the diagnosis of gynecological and obstetric problems during pregnancy and in the setting of acute abdomen during pregnancy. MRI overcomes some of the limitations of ultrasound, mainly the size of the gravid uterus. 4 MRI has even been proven to help in diagnosis of brain and spinal cord development of the fetus. MRI can delineate the development of the subcortical brain structures at the midtrimester of pregnancy and can obtain the normal measurements of these structures. It can provide certain help in evaluating fetal brain development in the uterus.5 As mentioned previously, MRI can help attain a clearer imagine than ultrasound in cases of oligohydramnios and also in obese mothers. Although it is the primary method of fetal imaging, it cannot provide sufficient information about the fetus in some conditions such as maternal obesity, oligohydramnios and engagement of the fetal head. At this stage, magnetic resonance imaging (MRI) facilitates examination by providing more specific information.6 MRI is also considered safe for the fetus because it does not require any type of maternal sedation. Fetal MRI was introduced in 1983, but the ultra-fast MRI sequences

Functional Magnetic Tolerance Imaging

...processes that are represented in fMRI images (what activity in the brain is actually being observed?). Functional magnetic resonance imaging measures brain activity. It works by detecting the changes in blood oxygenation and flow that occur in response to brain activity by detecting the areas that consume more oxygen and to meet this increased demand blood flow increases to area. Due to this fact fMRI can be used to produce brain maps showing which parts of the brain are involved in a particular mental process. C.

Scientific Article

...Scientific Article 1 Intro to Psychology Risk-takers are smarter according to new study In a recent study using functional magnetic resonance imaging (fMRI), images taken of the brains of young men revealed major differences in what is called “white matter” between two separate groups of participants. The University of Turku in Finland under the direction of SINTEF claims young men that make quick decisions in risky situations have a highly developed neural network and are “smarter” than low risktakers. First each participant was given a personality test to assess the risk-taking propensity and susceptibility to peer influence. By doing this the researcher was able to separate the 17 right-handed, 18-19 year old males into two groups, high and low risk takers. The two groups reported to the Department of Radiology of the Turku University Hospital for two practice sessions. During the sessions they were shows a driving game with sets of 20 stop-light intersections. They learned how to play the game and then reported back for four testing sessions in an MRI scanner. The first two sessions were performed under a non-competition social setting and the last two sessions by surprise were under social pressure of a peer competition situation. Measurements were taken of the participants at each moment that decisionmaking took place wether to stop at the yellow light or try and make it through. Results showed that high risk-takers didn't hesitate for long before they...

The Role of Magnetic Resonance Imaging (Mri) in Diagnoses of Pituitary Gland

...The role of Magnetic Resonance Imaging (MRI) in Diagnoses of Pituitary Gland Name: Institution: The role of Magnetic Resonance Imaging (MRI) in Diagnoses of Pituitary Gland The pituitary gland is an important part of the body because it controls several hormonal glands such as adrenals and the thyroid. The gland is a nearly the size of a pea and has two parts referred to as the lobes (Maya & Pressman, 2010). The front part is the anterior pituitary while the back part is the posterior pituitary. The pituitary gland is part of a bony hollow called the pituitary fossa behind the bridge of the nose and below the brain’s base near the optic nerves. Maya and Pressman (2010) add that the pituitary gland is the most important part of the system because it produces hormones controlling the functions of other endocrine glands. The most common problem occurring in the pituitary gland is the development of a benign growth or tumor. The tumor causes the gland to secrete excess hormone, blocks its production or causes it to malfunction. Other causes of pituitary disorders include traumatic brain injury and pituitary infarction. Although pituitary disorder are able to alter quality of a person’s life significantly, medical or surgical treatment is available where efficient diagnosis is made. The present study investigates the role of imaging modalities in the evaluation of pituitary gland disorders. Particular emphasis is laid on the role of Magnetic Resonance Imaging (MRI) in diagnosing...

Fmri Understanding

...“Critically consider how advances in fMRI scanning have contributed to our understanding of the systems, processes and functions of human memory.” Introduction: The aim of this essay is to critically consider the advances in fMRI scanning to our understanding of the systems, processes and functions of human memory. fMRI (functional magnetic resonance imaging) is a functional neuroimaging procedure using MRI technology that measures brain activity by detecting associated changes in blood flow. We are going to explore these three areas in depth, finding support and critiques for each one. As this is a big debate in neuropsychology there are several theorists supporting this debate and also critiques that have different views on this subject. Memory is the process in which information is encoded, stored, and retrieved. Encoding allows information from the outside world to reach the five senses in the forms of chemical and physical stimuli. Without a memory of the past we are unable to operate in the present and think about in the future. Henson 2006 used fMRI to compare single and dual processes of recognition memory. According to single processes items that are presented and remembered compared to those that are seen familiar (knowing) differ only in memory strength. However dual processes state that the ‘remember’ and ‘know’ judgements are qualitatively different as they rely on two distinct memory processes. Therefore Henson 2006 argued that any qualitative fMRI data between...

Segmentation Using Neural Networks

...supervised classification (SC). In this paper we approached an algorithmic method that aims to combine UC and SC, where the information obtained during UC is not discarded, but is used as an initial step toward subsequent SC. Thus, the power of both image analysis strategies can be combined in an integrative computational procedure. This is achieved by applying “Hyper-BF network”. Here we worked a different procedures for the training, preprocessing and vector quantization in the application to medical image segmentation and also present the segmentation results for multispectral 3D MRI data sets of the human brain with respect to the tissue classes “ Gray matter”, “ White matter” and “ Cerebrospinal fluid”. We correlate manual and semi automatic methods with the results. Keywords: Image analysis, Hebbian learning rule, Euclidean metric, multi spectral image segmentation, contour tracing. Introduction: Segmentation can be defined as the identification of meaningful image components. It is a fundamental task in image processing providing the basis for any kind of further highlevel image analysis. In medical image processing, a wide range of application is based on segmentation. A possible realization of high-level image analysis principle is the acquisition and processing of multisprectral image data sets, which forms the basis of the segmentation approach. A good survey is provided by the list of citations published in [1] that may serve as a good...

Mr Imaging of the Knee in Marathon Runners Before and After Competition

...MR imaging of the knee in marathon runners before and after competition A study was done to evaluate the findings in MRI-studies of the knee in recreational long-distance runners after competition and to assess the reversibility of the findings. The study consisted of eight long-distance runners and they underwent MRI studies before they ran and after. They participated in the Vienna City Marathon and MRI was taken place after 6-8 weeks. They were evaluated before in order to determine if there was a pre-existing condition. However, if a participant had any pre-existing condition they were still accepted to be a part of the research study. The participants were male and the age ranged from 27- 46 years old. They also had a long history of running at least 5 to 20 years. Before the competition started there were three runners that presented normal lateral menisci. There was eight grade I lesions; four grade II and three grade III lesions. “One participant who underwent resection of the posterior horn of the lateral meniscus 15 years previously and presented with a graded IIIB lesion of the posterior horn of the lateral meniscus in the other knee. After running there was no signal alteration that graded differently from the initial findings”. The MRI scans of those participants that were healthy before the race with no previous muscle injuries, after the marathon the MRI scans proved that no negative long-term-effects were experienced. In contrast, those that previously...

Demand vs Supply Paper

...seeking care. The value of a new medical technology is determined by supply and demand (Getzen, 2007). Diagnostic radiology is a prime example of the value being determined by both supply and demand. As radiologic imaging advanced from two dimensional x-ray images to three dimensional ultrasound images, magnetic resonance imaging (MRI), and Computed tomography (CT) providing better image quality and increased accuracy of diagnoses, the demand for these services rose. Statistics show that from 1996 to 2006 the frequency of radiology imaging increased nearly 60%, from 61 million studies to 99 million (Klein, 2008). This significant increase in use is directly related to enhance image quality used for diagnosis. This figure will continue to rise as more baby-boomers use these services to diagnose potential health issues that can be determined through radiologic imaging. This paper will discuss the demand and supply of outpatient radiologic imaging centers within the United States health care industry. Outpatient Radiologic Imaging Statistics indicate the growing use of radiologic imaging for diagnosis of health ailments. This demand has created a strain on the ability of hospitals to adequately supply all patients with access to diagnostic radiologic imaging without delay. This...

My Paper

...Many people wonder how psychologists know that a particular part of the brain is associated with a certain function. Researchers have used different techniques to study the brain. Researching the brain is not new. Back in the 1800s, phrenology was a popular technique. Phrenology was a procedure that used bumps on an individual’s head to determine and predict personality characteristics. Unfortunately, it is not very accurate. We have found more reliable information from lesions in the brain. A lesion is the natural or intentional destruction of brain tissue. Knowing what happens when a part of the brain is damaged or destroyed is a key to knowing its function when it works correctly. In 1848, a railroad worker named Phineas Gage FIGURE 3- 10 suffered an accident when an explosion drove a 1-pound steel rod straight through his head, destroying much of the front part of his brain. Some of the reports after the accident suggested that his personality was altered. Gage’s case underscores the fact that examining lesions is an important way to study the functions of various parts of the nervous system. Today, more sophisticated technologies are employed to study and treat the brain. For example, electrical stimulation of the brain is a technique used to stimulate neural FIGURE 3- 10 Phineas Gage suffered an accident that damaged his frontal lobe.
