The development of the MRI scan represents a huge milestone for the medical field. Physicians and radiographers can examine the inside of the body in high detail, using a non-invasive and non-radiation tool.
It differs from x-rays and a CT-scan, as it does not ionizing radiation, but rather magnetic fields and radio waves. It is a painless procedure, however, can take up to 45 minutes. If you are claustrophobic, a sedative can be administered and you will not be allowed to drive or operate dangerous apparatus. Sometimes intravenous contrast must be administered. Please inform the radiographer of any allergies or medical conditions, pacemakers or other implants or instrumentation.
Take note:
Depending on the area that will be examined, you may want to wear loose, comfortable clothing. You may be asked to change into a gown for the examination and to remove any jewellery or other metallic items from your body before the examination.
Magnetic resonance imaging (MRI) is a technique that uses a magnetic field and radio waves to create images of the organs and tissues within your body. An MRI scanner is a cylinder that’s open at both ends. The scanner will make loud tapping noises at certain times during the examination – you will be given headphones to wear.
During the examination, it is vital to stay still as any movement will disrupt the image.
The radiographer will sit in a separate room and will be able to hear and see you, and you will be able to communicate via an intercom.
