Magnetic Resonance Imaging Essay

Magnetic resonance imaging is a easy checkup test that is occasiond by physicians to diagnose and treat their patients. magnetic resonance imaging does non depend on radiation in articulate to make water an immanent check of a body unlike x-ray examination and CT scan. It uses a powerful magnetic field and as easy as radio waves with the help of a computer in order to be equal to(p) to produced detailed views of a persons organs, tissues and new(prenominal) details most the patients internal body structure. Using magnetic resonance imaging, hydrogen atoms in the body are aligned through the used of a electronic scanner that produces a powerful magnetic field.In order to change the coalition of this magnetization, radio waves are used which overly causes the hydrogen atoms to be able to create a weak radio signal that are instanter measurable. Additional magnetic field enables the manipulation of these signals to be able to put on enough information. A computer then g enerates a series of image through the use of the gathered information. These images are then compiled to produce a three-dimensional image of the persons body. The formed images can at present be seen on a computer monitor for examination and stock-still printing.The images are analyzed by a radiologist and will fall in the report on the attending physician. In this case Physics and another(prenominal) sciences are really helpful and is really the key for the production of such(prenominal) method. Without our knowledge regarding magnetic fields and radio waves as well as the machineries, magnetic resonance imaging will not be possible. Some of the uses or magnetic resonance imaging includes the evaluation of chest organs, the abdomen and pelvis. The MRI is also used by physicians in order to diagnosed different tumors of the body and for several other medical examinations.The traditional design of Magnetic Resonance Imaging unit is a large tube that is cylindric in shape. Circ ular magnets surround the cylindrical tube. The patients are then placed in a movable control panel and slides into the center of the magnets for the examination. Other MRI units had been designed so that the magnet does not completely surround the patient and still, there are those that are undefendable in every side. These modifications are made for patients who does not like being in a close space. However, the traditional design still gives the dress hat image quality.Advantages and Disadvantages of MRI One of the main benefits of utilise MRI for diagnosing is that it does not use radiation. Also, the images formed using this procedure is has a high sensitivity that enables easily identification of abnormalities that are present in the body. It had also been proven that MRI plays a great role for diagnosing passageway range conditions such as heart disease, muscular and bone abnormalities and as well as cancer.Another advantage is that MRI does not that allow the attendi ng physician to have a view of the internal body structure of the patient but as well as how that particular organ works. MRI also makes it possible to detect other abnormalities that may be hidden in the bone, abnormalities that may not be seen using other imaging methods. The materials that are used in MRI are also likely to produce less allergic reactions compared to the use of other imaging method such as x-rays and CT scan.As long appropriately guidelines for safety are followed, MRI poses almost no risk to most of the patients. The main risk or disadvantage of using the MRI is that the devices used that contain metal may malfunction during the MRI exam. Also if the examination uses sedatives, there could be risks because of the use of excessive sedatives. static this risk can be minimized by the nurse by checking the vital signs of the patient.
