This technique provides very clear and detailed images of internal organs and tissues. MRI is a relatively safe, non-invasive and painless form of imaging.  \nWhat to Expect During the Procedure  \nYou will be asked to lie down on a padded table which will be moved into the scanner. Once you are comfortably positioned, it is important to relax and keep completely still during the scan as movement will result in unclear images.  \nIt is common to hear knocking, humming and thumping sounds during the scan. Ear plugs will be provided to muffle the sound. An intravenous cannula will be inserted into your arm or back of hand if contrast is required for your scan.  \nYou can expect to spend approximately two to three hours at the imaging centre. While the procedure itself will take between 30 to 60 minutes (depending on the type of investigation you require), you will be required to go through the pre and post procedure preparations. It is therefore advisable that you do not schedule other appointments within this period.  \nOn the Day of Procedure  \n􀁸 You will need to fill in a safety screening form prior to the start of the procedure.  \n􀁸 The radiographer will explain the procedure and answer any questions you may have.  \n􀁸 You will be required to remove items such as wallet, watch, keys, magnetic strip cards (e.g. ATM, credit card) as the force of the magnetic field can attract such magnetic objects and/or erase and alter the information in them. Lockers are provided for storage of your belongings.  \n􀁸 You will need to change into our examination gown in preparation for the scan.  \n􀁸 Relax, keep completely still and breathe normally throughout the scan unless instructed o","cbCaioiaQon7PNLd","https://ap.wps.com/l/cbCaioiaQon7PNLd","pdf",443745,"English","# Preparation Instructions for Patient\n## IMPORTANT REMINDERS\n## Fasting and Sedation Preparation\n# What to Expect During the Procedure\n# On the Day of Procedure\n# After the Procedure\n# What Are the Risks\n## Allergic reactions and contrast risks\n## Undetected metal implant risks\n# Contact Information","[{\"question\":\"What should patients report during the MRI safety screening?\",\"answer\":\"Patients must highlight any relevant conditions that may compromise safety or interfere with the MRI scan, including metal implants, pacemakers/defibrillators, shrapnel/metallic foreign bodies, stents, hearing devices, prosthetic parts, and other implanted devices.\"},{\"question\":\"Is fasting required before an MRI?\",\"answer\":\"No fasting or preparation is required for most scans, except for MRI fetal scans and patients requiring sedation.
