Extract of sample "The MRI scanners"

Download file to see previous pages The new scanner is designed to create a new kind of imagining called a fMRI, this type of scan uses a noninvasive technique to produce images that have such a high resolution that even a single millimeter of an area of the brain could be distinguished. This is very important during the procedures in which surgery is required to treat tumors and epilepsy for instance) that can effect brain tissue near cerebrum or the areas that control movement, the newer versions of the scanner have contributed to developing additional magnetic resonance technology. MRA or Magnetic resonance angiography is a test that is used to evaluate blood flow through the arteries without cutting it open to see. MRA is also used to detect aneurysms within the brain and abnormalities of the blood capillaries in the brain, spinal cord or in the other systems of the body. Magnetic resonance spectroscopy (MRS) is another noninvasive procedure done by using MRI scanners is to assess chemical abnormalities in the tissue such as the brain. It is can be used to diagnose diseases such as HIV-AIDS, infections of the brain, stroke, Alzheimer's disease, tumors, and multiple sclerosis. To determine the specific location is a brain where a certain function such as memory or cognitive development occurs functional magnetic resonance imaging is used this is useful because even though the human brain is the same in every human but the exact location of some general areas may vary, during this scan the patient might be asked. ...Download file to see next pages Read More

Diagnosis of knee joint problem in MRI

...The use of magnetic resonance imaging emerged in the early 1980’s where its usefulness was highly rated. Most clinicians saw it as a way of gaining proper medication and diagnosis for the knee treatment and a clear indication of progress in the treatment of patients with different knee problems. However, with the high cost of the MRI, most of the surgeons reverted to the earlier and cheaper means of treatment which included the clinical examination findings. Despite the fact that the MRI was seen as a golden standard of accuracy and precision, it suddenly became very expansive for most patients to afford a scan which according to Rose & Gold (1996) was rated as costing $1000 or more per scan. Though this reason is enough to forego...

Mammography and MRI Coverage for High-Risk Women

... Mammography and MRI Coverage for High Risk Women Introduction Breast cancer is one of the commonest types of cancer in women. American Cancer Society statistics show that approximately 40,000 women die in the US of breast cancer each year (Elting et al, 2009). Annual statistics indicate that more than 200,00 new cases of breast cancer are diagnosed on a yearly basis. In about 10% of cases, the disease is hereditary resulting from mutations in the BRCA ½ genes (Elting, 2009). The remaining cases are sporadic in nature, occurring in women with no family history of the disease. . Epidemiological studies show that African American women have the highest incidence of breast cancer and are 30% more likely to die of the disease than...

...Root causes of the Problems on Safety. MRI accidents are 100% preventable (MRI safety video) and the key root cause of any problems is human fallibility. Assuming that the MRI facility is designed and run according to best practice guidelines, staff training is the single most effective way of addressing safety issues. The deficits that staff training aims to address are the following: 1. A lack of knowledge about the potential risks associated with the equipment. [Proposed response: general training for all staff, plus specific training for different groups of staff. Responsibility: corporate training team] 2. Absent or incomplete rules and protocols for activities in the vicinity of the equipment [Proposed response: research...

MRI (Classical theory Magnetic resonance)

...Question Magnetic moment is the property of the element which is due to the basic structure and construction of the smallest element of the element i.e atom. An atom is composed of the nucleus (neutrons and proton with electrons revolving around the nucleus in orbits. The most basic features of the atom depend upon the two basic entities (1) Atomic number (z): it is the total number of protons inside the nucleus of the atom and (2) Atomic mass number (A): it is the total number of protons and neutrons inside the nucleus of the atom. Both of these entities play a significant role in producing a MRI active nuclei having active magnetic moment property. In electromagnetic laws a nucleus spining around its own axis with an electric charge...

Physics MRI

... that B = 3.0 T, the energy difference also doubles, since ΔE is directly proportional to B, by the equation above. From above, we had the equation: ΔE = ħ γ B Look at the equation above. Hbar and gamma are constants ; so if I double B on the right hand side of the equation, the energy difference (delta E) on the left hand side of the equation will have to double in response. Please calculate also doubles, since For an x-ray of frequency 2 x 1019 Hz, the energy of the photon is calculated to be The significance of the relative energies used in MRI and CT, is that MRI uses the energy difference calculated above for the hydrogen nucleus states, which is on the order of 10-27 J; this is much smaller than the energy of the x-ray photon...

Magnetic Resonance Imaging (MRI)

... area during use, the radio waves and the magnetic fields are relatively harmless and pose no serious impacts during normal procedures. Child Expectations during MRI The scanner for MRI resembles a huge box that is square shaped and with a tunnel-like hole running through the middle. The user requests the child to lie down on a table that is cushioned with aids such as soft traps and foam cushions employed to ensure the child remains still during the process. A unique frame which slightly resembles a helmet is placed on the part of the body of the child that has been earmarked for observation. When the child has been set in a comfortable and appropriate position, the table begins to move by default into the tunnel of the MRI. At this point...

Lumber Spine Disc Prolapsed in MRI

The painful and incapacitating prolapse of a lumbar spine disc or discs is one of the commonest problems which can affect the spinal column in humans. The main cause is poor posture and many people with this condition are older people. There are of course many other spinal conditions such as spinal injuries, tumors and innate abnormalities. Any or all of these will result in pain and possible incapacity.
Many of these abnormalities are related to the particular area of the lumbar spine. Such people become hospital patients and need the best possible treatment that modern medical knowledge and technology can provide in order that they recover as quickly as possible, and can return to their normal activities as soon as possible w...

Current and Emerging MRI Techniques

Diffusion tensor imaging (DTI) is an imaging technique that helps to understand fibrous structures of the body in details such as muscles and white matter.
DTI is based on the physiology of the cell membranes and protein molecules of the muscular tissue that often limit and rate the diffusion of water molecules in a single particular direction. However, water diffusion rate is faster along the longitudinal axis than its transverse axis. DTI defines the infrastructure of the cells by calculating diffusion rate of the water molecules. Tensors measure this independent diffusion of water molecules corresponding with the principal eigenvalue of the long axis of muscle fiber. As per Villanova et al, “It was the first imaging mo...
