Generally, MRI scans are considered a safe procedure, but there are a few things to consider.
Understanding MRI Safety
MRI, or Magnetic Resonance Imaging, uses powerful magnetic fields and radio waves to create detailed images of the inside of your body. Because it doesn’t use ionizing radiation like X-rays or CT scans, it’s generally considered safer. However, some potential risks exist.
Potential Risks:
- Metal Objects: The powerful magnetic field of an MRI scanner can cause metal objects to move, potentially causing injury. This is why you need to remove jewellery and other metallic items before a scan.
- Example: A metal necklace or belt buckle could be pulled towards the magnet.
- Internal Metal Devices: Individuals with internal metal devices, such as pacemakers, can be at risk. The magnetic field can disrupt the proper functioning of these devices.
- Example: The magnetic field might interfere with the operation of a heart pacemaker.
The Reference States:
The MRI scan is a very safe procedure. Occasional complications may include: Metal objects (such as jewellery) worn during the scan can cause injury. The powerful magnetic field of the MRI scanner may damage internal metal devices, such as a heart pacemaker.
Summary:
MRI scans are considered safe procedures overall. However, it's crucial to follow instructions from healthcare professionals regarding metal objects to avoid potential injury or complications.
