Magnetic Resonance Imaging (MRI) is a revolutionary medical imaging technique that uses a strong magnetic field and radio waves to generate detailed images of the body's internal structures. It provides valuable information for diagnosing and monitoring a wide range of medical conditions without using ionising radiation.
During an MRI scan, the patient lies on a bed that slides into an open cylindrical bore called an MRI scanner. The scanner has a magnetic field and uses radio waves, causing the atoms in the body's tissues to emit signals. Specialised detectors in the scanner capture these signals, which are then processed by a computer to create detailed cross-sectional images of the body.
MRI scans do not involve the use of ionising radiation, such as X-rays or radioactive materials. Instead, it relies on the natural magnetic properties of the body's tissues and the radio waves to generate the images. This makes MRI a safe imaging modality.
It is essential to follow any specific instructions provided by your healthcare provider or the Reform Radiology team regarding preparation for the MRI scan. If you have any concerns or questions about the procedure, do not hesitate to discuss them with our friendly team or your healthcare provider.
Preparing for an MRI scan:
The MRI technologist will complete the safety check with you. We will then take you into the scanner room. You will be positioned on the examination bed, and we will try to make you as comfortable as possible.
The MRI technologist may place imaging devices on the region that will be examined. These can send and receive radio waves from your body to create the images.
The doughnut shaped MRI scanner is open at both ends. The body part being examined is placed into the center of the MRI scanner. During your examination you will be given a squeeze ball (patient safety bell) in case you need assistance during your scan. Our staff can see and hear you the whole time so please know that you are safe.
The MRI scanner makes a variety of loud noises during the scan and the MRI technologist will provide hearing protection in the form of earplugs and headphones.
Sometimes we will ask you to hold your breath during the examination. This will be important especially when we examine your chest or abdomen.
If contrast is required for the scan, an MRI technologist or Radiologist will insert an intravenous catheter (IV line) into a small vein in your hand or arm. The contrast provides additional detailed information that helps the Radiologist interpret your images.
After completion of the exam, the MRI technologist may check with the Radiologist to find out if more images are required and will then let you know.
The IV line will be removed, and a small dressing placed over the insertion site.
Your images are extensively interpreted by a specialised doctor (Radiologist). The Radiologist will issue a formal exam report which is then sent to your clinician in a timely manner.
