Magnetic resonance imaging (MRI) is an absolutely safe and painless test. It uses a magnetic field and radio waves to generate detailed pictures of the organs and structures in the body. It might interest you to know that MRI varies from a CAT scan (also known as a CT scan or a computed axial tomography scan) because it does not use radiation.
An MRI scanner is formed of a huge -shaped magnet that most of the times has a tunnel in the middle. Patients are laid on a table that slips into the tunnel. There are centers that have open MRI scanners that have big openings and are assistive for patients with claustrophobia. You can find MRI machines in the hospitals and radiology labs. You can find good MRI scan in Bangalore too.
What happens during the procedure?
During the procedure, radio waves manipulate the magnetic angles of the atoms of the body. These are picked up by a robust antenna and sent to a computer. The computer carries out millions of calculations, ending up in clear, cross-sectional black and white pictures of the body. These are the images that then get converted into three-dimensional (3-D) pictures of the scanned zone. With the help of these images, the doctors are able to pinpoint the problem or issues in the body. Wherein in the past the doctors and surgeons used to do a lot of guesswork about whether there is a problem or not inside the body or specific organ or issue; these days with the help of MRI, things have become easier and much more effective.
What is the purpose of MRI?
MRI is performed to detect a diversity of conditions like problems related to the brain, skeleton, spinal cord, chest, abdomen, lungs, pelvis, hands, wrists, ankles, and feet. In some instances, it can cater clear images of body parts that cannot be seen as well with a CAT scan, X-ray, or ultrasound. MRI is specifically valuable for diagnosing issues with the ears, eyes, heart, and circulatory system. The ability of an MRI to highlight contrasts in soft tissue underlines it as an absolutely useful tool in deciphering issues with cartilage, joints, ligaments, and tendons. MRI can also get used to discover infections and inflammatory situations or to exclude problems such as tumours.
What preparation is needed for this scanning?
In many instances, undergoing an MRI demands no type of special preparation. However, any kind of metallic objects often generate a blank spot or bright spot on the diagnostic film. The technician is going to have you remove any type of objects that contains metal, like eyeglasses, belts, jewelry, or credit cards. Electronic devices are never allowed in the MRI room. However, remember that braces and dental fillings are not going to interfere with the scan. Similarly you would also be asked questions to make sure that you have not have any internal metal clips from surgery in the past or anything else that could trigger a problem near a powerful magnetic field. In simple words, the patient is even told to change into the hospital gown to ensure that they are not wearing anything that might have even an inch of metallic items.
To receive the highest quality MRI results, the patient would need to stay completely still during the scan. It is the reason that sedation may be needed during the procedure of MRI. This is common in infants and that of young kids. In case sedation is required then any type of food and liquids are going to be stopped at a certain point before the procedure of MRI to permit your stomach to empty. It is important to notify the MRI technician or experts of any allergy, illness, previous drug reactions, or even that of pregnancy. If you have any type of health condition you should talk about it with the technicians so as to rule out any type of problems.
For young kids who are probable to have challenge staying still for the test, sedation medications are generally given through an intravenous (IV) line. In simple words it is a tube to help them stay asleep during the whole procedure of this test. Sedation is also effective if a child is claustrophobic. To relieve fearfulness before and during the test, some patients also consume an oral sedative on the way to the hospital or in the radiology center. So, it is not specific to kids but any patient who is not comfortable with scanning procedure is given this sedation.
In the case of kids, being a parent or guardian, you can stay in the MRI room with the child until the exam begins, and in some centers you might be allowed to stay throughout the test. In case you are not allowed to stay in the room, you can join the technician in an adjacent room or be asked to stay in the waiting room. In case you are nearby, you will be in a position to watch through a window and talk to the child via an intercom during breaks between scans. It can soothe your child if he or she is up in the MRI machine.
Procedure of MRI
An MRI examination generally takes twenty to ninety minutes to get performed. It depends on the type of study getting performed. Your child will lie on the movable scanning table while the technicians place him or her into position. The table is going to slide into the tunnel and the technician will take pictures. Every single scan would take up a few minutes.
To discover specific problems, the patient might be given a contrast solution via an IV. The solution, that is painless as it goes into the vein, enhances certain areas of body. These are the areas like vessels, so doctors can see them in an effective a detailed manner. The technician ass if the patient is allergic to any medications or food before they give the contrast solution.
So, if you are going to take your child or you are going for MRI, just pick the best MRI centre in Bangalore and stay confident. There is nothing painful in the entire procedure!
