MRI’s are a diagnostic test that uses powerful magnetics to view the body inside, as with the tissues and bone without having to operate. These types of tests are usually performed by a highly trained x-ray technician, who has studied to be able to successfully operate this type of diagnostic equipment. The magnets in an MRI are created by electricity, and when activated, they create radio waves that then create signals to computers to interpret the images. What is fascinating is that in this type of innovative imaging a physician can obtain results that are three dimensional. These types of tests have improved healthcare in phenomenal ways by allowing a view inside the body, which before was a mystery.
Many people who have to undergo such a scan are usually a bit apprehensive due to the nature of the test. One is told to be very still, as they lie in a large mechanical tube like device. It can seem that one may become claustrophobic because of the small space, and at times some patients panic. As explained at Xraytechnicianeducation.com, good technician will be trained on how to handle such situations so that the patient will be at ease.
When one is to undergo an MRI, it is important that the doctor and technician go over all the pertinent medical history with the patient, including previous operations and if there could be any metal parts in their body. If these measures are not detected, it can make for an unpleasant experience for the patient, due to the magnetic energy and its attraction to metals. Usually a hospital gown is provided as to alleviate any metal on clothing. It is up to the technician to position the patient on the imaging table and if any additional views are ordered, as in a contrasting image, an injection of contrasting substance is injected at this point.
At the time the patient has been successfully prepared, the x-ray technician will step out of the room to begin the scanning. This type of imaging, for some, can really test their anxiety levels to a point, but it is important that they remain calm throughout the scan. It is possible that sedation may be required or a mild relaxant. The noises can be quite loud that emanate from the imaging machine, but there is no cause for alarm, they are just processing what needs to be imaged.
When the testing has been completed, if the patient has not been sedated, one can usually return home. If the patient has undergone sedation, they must go to recover in a quiet room until they are fully awake, which could be a few hours. One can usually return to normal activities the next day.
