Information About MRI Scans In Details – Magnetic Resonance Imaging (MRI)
Information About MRI Scans In Details Magnetic Resonance Imaging (MRI).MRI is referred to as magnetic resonance imaging. Radio waves, magnetism or computer are used to produce images of body structures. Not involving radiation it proves to be a painless procedure. Any patient with a metal chip around their eye or body is not liable for an MRI scan because of the impact of the magnet. You can term an MRI scanner as a tube replicating a massive circular magnet. A patient is being placed on a movable bed where they are inserted on to the magnet. They are exposed to beams of radio waves that develop images. These sets of images are then interpreted on a computer screen. MRI is an in-depth procedure that means tiny structures inside the body are found. In some type of procedure contrasting materials are used to enhance the quality of images.
Any risks or side effects associated with an MRI scan?
As discussed earlier MRI is a painless radiology procedure that has an impact of avoiding ionizing radiation. To date, no major side effects of MRI scans have been reported. The major benefit of such a scan relates to detecting structural problems with your body. If a patient has a metallic structure on their body, they need to notify a surgeon before a procedure is performed. Foreign materials or metallic structures are a still no during this procedure. As a patient, if you have had a pacemaker or metal chips then the eyeballs cannot be scanned and MRI has to be avoided. A risk is that magnet is known to move metal in these areas. Patients suffering from chemotherapy or insulin need to be avoided from an MRI scan.
During the process of scan, inside a magnetic area within a closed area, a patient lies down. For some patients, a Claus trophic feeling suffices. Any individual who has a history of such disorders needs to inform a doctor before this procedure. This applies to someone who is requesting the test along with the radiology staff. Before the MRI scan, a mild addictive is provided to cut down this feeling. During MRI scan it is fundamental that MRI staff has to be near vicinity. There are other means of communication with a patient like a buzzer on their hand. The patient can give signals if they are not able to tolerate such a scan.
The uses of an MRI scan?
MRI scan presents one of the most reliable methods of disease detection throughout the body. It is often relied on when other methods of testing fail to provide an accurate diagnosis. For example in your brain trauma can cease leading to bleeding or internal injury. Some other type of abnormalities includes tumors of the spine or the brain.
Neurosurgery not only relies on an MRI scan to detect anatomy of the brain. After the trauma integrity of a spinal cord is analyzed. This scan is also undertaken when issues of vertebrae emerge. Even the structure of your heart can be figured out with an MRI scan. For sure these scans are not going to be used for the first time in cases of trauma. The best part of an MRI scan is that it becomes easy to determine surgery is needed.
How is a MRI performed?
Before an MRI scan Chennai, all-metal objects are to be removed. In most cases, patients are given sedative medicine in order to relax and reduce anxiety during an MRI scan. For best accuracy, it is suggested that a patient goes on to lie in a still manner. In a closed environment, patients are asked to lie down in a magnetic machine. During the procedure, relaxation is important as patients are asked to breathe in a slow manner. At the same time interaction with a radiologist is maintained during the procedure. Once scanning procedures a series of sounds also emerge. At an occasional level, a patient might require injections to enhance the quality of images. The time of an MRI scan is dependent on the exact area of the body where it is done, though it should not exceed 30 minutes from half an hour.
How results of MRI are interpreted?
Once scanning ceases to be over, visual images of the area scanned are interpreted by a computer. On to a hard copy, the images can be transferred. A trained professional in the form of a radiologist interprets these images. You interpret is being transformed on to a report to a practitioner who has asked for an MRI scan. The results obtained would be then discussed with your family.
Of later new MRI scanners have emerged in the market with portable and smaller devices. With the help of such new scanners possibility of infections and tumors are detected of soft tissues in relation to the hands, feet. In the field of medical practice, the application of such scanners is considered.
The major difference between a CT scan and an MRI scan?
Before you opt for the best MRI scan center in Chennai you need to figure out the difference between MRI and CT scan. In the case of the CT scan, you rely on X rays so as to obtain images of the human body. It also goes on to use radiation which an MRI does not. Though via MRI in-depth information of the inner body organs are provided. This includes the soft tissues and other forms of reproductive systems.
CT scan is a painless and invasive procedure. On the other hand, MRI does not seem to be invasive but takes a lot of time and causes considerable anxiety due to the enclosed area of a machine. In addition to this MRI seems to be a lot costly than CT scan. With a CT scan, a combination of images from various angles is taken. Then the computer obtains images from such x rays.
With MRI you rely on magnetic fields or even radio waves of obtaining the image of the body‘s bones and tissues. With MRI scan of your organ system, a three-dimensional image is obtained.
