The basics of magnetic resonance imaging
During an MRI, you may be asked to remain still for as long as 30 minutes. Wearing comfortable clothing without metal such as a tee-shirt or cotton dress is a good choice. Your phone, credit cards, and jewelry should all be removed. Remove all magnetic objects, including rings and necklaces, from your body. You may need to be still for the images to be taken. An MRI machine will emit a radio frequency signal that directs the radio waves towards the part of the body that is being imaged. The radio waves and magnet will not affect your sensations.
Patients lie on a movable examination table, which is located outside the MRI machine. Patients should lie on their backs with their arms crossed and their heads resting on a support. A few small coils will be placed over the body of the MRI technologist. This will allow for clearer images. Before the scan, technologists will need to leave the exam room to go to a nearby control room. The technologist will be equipped with a video monitor and you can communicate with him via an intercom system.
MRIs can be expensive so it is important that you find out if you will receive reimbursement. Ask your hospital to give you a list containing all the procedures they have done. Before they consent to the scan, patients must sign a consent form acknowledging that they have read and understood the risks. To ensure they are fully informed about the scan and its benefits, patients can also ask questions of their healthcare team. They can ask questions and have the health team explain the test.
Remove any jewelry made of metal prior to the MRI. You should also remove any belts, earrings, or necklaces that may be affecting the scan. Also, you should leave behind your underwear and jewelry. Instead, you could wear a hospital dress. Keep in mind that vibrations and noises can cause interference with the MRI images. During the MRI procedure, you must also remain still.
MRI scans are radio waves that take images of your body. Some images will show fat tissue while others will show it. To assess the cerebral cortex, T1-weighted photos are used. T2-weighted photographs are used to diagnose focal liver lesions. These images may not be suitable for all kinds of problems. Talk to your doctor before you undergo an MRI.
While MRI does not emit ionizing radio, it does produce a magnetic field. This magnetic field exerts strong forces on metal objects and can cause a wheelchair or other mobility device to be tossed around in the room. Your doctor should know if there are any implants in your body. If you have a pacemaker or other metal devices, your MRI should not contain any. Pregnant women should avoid any form of iodine.
Make sure that you don’t have any metal implants prior to having an MRI. An implanted pacemaker could interfere with the results. Pregnant women should inform the technologist or radiologist. To avoid any complications, it is important that you remain still throughout the entire procedure. An MRI can detect abnormal heart conditions, pregnancy, or childbirth if you’re a woman. It is easy to do at home, and safe for women with any type of medical condition.
MRIs can be used in extremely safe settings. MRIs don’t use ionizing radio, unlike CT scans. They are therefore safe for children and pregnant women. An MRI may make you feel tired, but it is possible to remain awake during the procedure. After the test, you can take the rad.
