...2a. The Magnetic Resonance Imaging machine, MRI machines, is a computing innovation that uses two powerful magnets that produce strong magnetic fields, radio waves, and a computer in order to create a detailed pictures of the human body. 2b. 2c. The MRI machine has a wide variety of uses, One benefit of the MRI machine on the people of society is that it does not use ionizing radiation like Computed Tomography (CT) machines and X-Ray machines when they are used on individuals. Ionizing radiation is extremely harmful to the human body because it can damage the DNA inside living cells. This makes MRI scans reliable and safe. Although MRI are some of the safest types of medical scanning, the patient undergoing the scan could be in potential...

...Pena, Mary Edilie P. Bs Psychology II-A ChemLec101F Magnetic Resonance Imaging A Paper Requirement in Inorganic Chemistry Magnetic Resonance Imaging (MRI) also called as Nuclear Magnetic Resonance (NMR) is a unique imaging technique that can scan the body without cutting inside the human body, gets images of the human body through scanning with the use of magnets and radio waves to create images and could serve as a valuable addition to diagnostic medicine. The patient lies on a patient table then slides into the cylinder and placed in a magnetic field gradient. When operated, protons are tiny particles that are present in water molecules in the body and protons aligned in parallel to the powerful magnetic field. Radio waves are transmitted in pulses and these protons are echoed along the body. When the MRI machine is scanning, the MRI scanner receives the echoes and it will construct a clear and detailed image of soft tissues of the body to a computer that creates an image based on the radio signals emitted from the body. The whole procedure can take 20-40 minutes or can take even longer. The scanner is very loud, so patient will be required to use earplugs or headphones to protect their ears from the noise. Magnetic Resonance Imaging is important because MRI scan can investigate or diagnose conditions that affect soft tissues such as abnormal tissue like tumours, joint or spinal injuries or diseases, and soft tissue injuries or diseases of internal organ like brain or heart...

...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.

...Magnetic resonance imaging, aka MRI, is a scanning technique to produce detailed 3 dimensional anatomical images of the human body in any direction by using a magnetic field and radio waves. The pictures provide information that can be useful in diagnosing a wide variety of diseases and conditions. Radio waves cause the molecules to create faint signals that are used to view the body in narrow, axial slices. How does MRI Work? An MRI scanner has a large magnet with a tube shaped tunnel through the middle. The MRI machine picks up signals from the nuclei of the hydrogen atoms in the body. A computer converts these signals them into a black and white picture. The magnets from the MRIs develops a strong magnetic field that makes the protons to align with the field. When the radiofrequency pulses are sent in, the protons are stimulated and makes them non-equilibrium, a state of the chemical reaction in which the opposing forces are not balanced. When the pulses are off, the particles produce electrical signals...

...MRI(Magnetic resonance imaging) MRI is a instrument commonly used in a medical diagnostics. MRI stands for magnetic resonance imaging, it is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. A MRI can give different information about structures in the body than can be seen with an X-ray, ultrasound, or computed tomography (CT) scan. It measures the water content of tissues within the body, which is processed by the computer, creating a black and white image. A MRI can produce a highly detailed image, showing even the smallest abnormality. A MRI uses strong magnetic fields and radio frequency waves to create images of the human body. A dye containing gadolinium, has magnetic properties that are used during the procedure. It will then circulate through the blood stream and absorbed into certain tissues, that stand out on the scan. The wavelength is somewhere between 4.6m and 3.5m. MRI is the best type of imaging to diagnose most types of brain tumors. They use magnetic fields and radio waves, rather than X-rays, and computers to create detailed pictures of the brain. MRIs show “slices” of the brain that can be used to create a three-dimensional picture of a tumor. The contrast dye is used to enhance the images. When having an MRI done, the area of the body being studied is placed inside a special machine that contains the strong magnet.The standard MRI machine looks like a long cylinder with a narrow...

...Open Bariatric Imaging Diagnostic imaging gives MRI Specialists an accurate representation of what is happening inside a patient’s body. Once complete, the MRI Center gives the patient’s physician a report detailing the results of the scan. These results help a physician determine which treatment is best suited for the injury or condition. A traditional MRI machine is not designed properly for a bariatric patient. Because there are numerous medical conditions and ailments that cannot be accurately diagnosed without the use of state-of-the-art equipment like Open Bariatric Imaging machines, when a physician orders a Magnetic Resonance Scan for a bariatric patient and/or a patient who becomes anxious in tight spaces (claustrophobia), finding a facility with an MRI scanner designed for these patients is essential. MRI Specialists can...

...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.

To have someone look at you as though they don’t know you? Or have you ever wondered why they call it Alzheimer’s disease well according to the National Institute on Aging is named after Dr. Alois Alzheimer, he had noticed changes in the brain tissue of a woman that died of an unusual mental illness. The woman’s symptoms included memory loss, language problems and unpredictable behavior. After she had died he had found many clumps in the brain which are now called amyloid plaques and tangled bundles of fibers called neurofibrillary tangles. Plaques and tangles of the brain are the two main features of Alzheimer’s disease, so as you can he is the one who first discovered Alzheimer’s disease and that is why it is named after him. Now although I have not had any kind of experience with this disease, I felt that it is an important disease to research because I want to know how to prevent this disease from happening to me or someone that I love. In order for me to do this I have to understand why and how the parts of the brain that causes this disease to malfunction and cause people to lose their memory. According to the Cleveland Clinic Alzheimer’s disease is a progressive disease that damages...

...Studying the brain can be a hard thing to accomplish. There are quite a few methods that our bio psychologist’s use to study the brain. As stated in Biopsychology 8 Ch5, “Some of the methods used to study the brain include: X-rays, contrast x-rays, magnetic resonance imaging (also known as MRI), positron emission tomography (also known as PET), and in my opinion the best way of studying the brain; functional MRI.” Unlike using just MRI to visualize the brain; functional MRI is a great way to study the activity of the brain, while being able to visualize the brain. When using just a magnetic response imaging machine to study the brain, the only great thing about using it is being able to visualize what is going on in an individual’s brain. For example; if someone were to have an appointment to look at their brain, to determine whether or not they have a tumor; this type of method would be a great method to use. The reason I say this is because an MRI machine is able to visualize if there is anything growing inside the brain. While an MRI may be a great method to use for this type of procedure; a functional MRI would be able to not only visualize what is growing in the brain; it would be able to show the doctor the activity of the tumor and other activity in the brain. As stated in Biopsychology 8 Ch5, “Functional MRI produce images representing the increase in oxygen flow in the blood to active areas in the brain.” Another great aspect of Functional MRI’s are that unlike other...

All other history of implants or surgery must be indicated to the technologist. The make and model of implants may be necessary (i.e. ear implants, heart valve replacements). The Exam Your exam will last between 30 and 60 minutes. You will need to lie still for periods of 3 to 10 minutes at a time while the series of images are collected. You can breathe freely during this time. You may, in some cases, be allowed to move slightly between scans, but not so much that your position changes. The imaging session creates a series of repetitive knocking sounds when the magnetic field gradients are turned on and off. Listen to the following audio segment as an example of the sound generated by a magnetic resonance imager while an image is being acquired. Because of the volume of these sounds, it is recommended...

...“In-Depth Mobile Radiology” - A Marketing Plan Background IN-DEPTH MOBILE RADIOLOGY is a new medical staffing and mobile diagnostic company that caters to medical facilities that are in need of our services. Our company provides a couple of types of service who are in need of diagnostic machines or technologists. The first type of service is acquiring trailer truck based mobile MRI or CT scanner machines or providing ultrasound and mobile x-ray machines. The market is open for medical facilities, nursing homes or rehabilitation centers that do not have their own diagnostic equipment and instead of purchasing their own machine that cost so much our company can offer our services to bring our mobile machines into their facilities parked outside gets all their procedures done for the cheapest price possible. The second type of service is staffing for surgical centers or medical facilities providing technologists that would operate the advanced fluoroscopic x-rays, CT scans, MRI, ultrasound, bone density and other medical diagnostic equipment that needs a certification to operate. Most medical facilities have procedures daily but not all of their cases need x-ray, so it would be best for them to hire a temp rather than have a regular tech. IN-DEPTH MOBILE RADIOLOGY will base its main facility in the area of Palm Springs and Indio California by the 10 freeway for easier access to walk in clients. After surveying the area of southern California, we found that the Palm Springs...

...Stark Law and Radiologic Imaging Stark Law: some people consider it a highly needed federal law to help protect patients and insurance companies; others dread even the name and feel that it is just another way the federal government interferes with individuals’ daily lives, and see it as an unwanted intrusion into the practice of medicine. What is Stark Law and why was it enacted? Stark Law is actually three separate provisions that govern physicians’ self-referrals, mostly for payment by Medicare patients; it is also known as “the self-referral law.” “The law is named for United States Congressman Pete Stark, who sponsored the initial bill (“STARK LAW,” n.d., para. 1). The first phase became effective on January 1, 1992 (Taromina, 2013, p. 83). It prohibited a physician from referring a patient to a clinical laboratory with which they, or an immediate family member, had a financial relationship. The second phase became effective on January 4, 2001 (Taromina, 2013, p. 83). Stark II applied the already-enacted laws to Medicare and Medicaid patients, and extended the restrictions to include additional designated health services (DHS): physical therapy, occupational therapy, speech therapy, radiology services, radiation therapy, durable medical equipment and supplies, parenteral and enteral nutrients, equipment, and supplies, prosthetics, orthotics, and prosthetic devices and supplies, home health services, outpatient prescription drugs, inpatient and outpatient hospital services...
