What is MRI?
MRI stands for Magnetic Resonance Imaging. It is a medical imaging technique that uses a strong magnetic field and radio waves to create detailed images of the inside of the body.
What are the benefits of MRI?
MRI can provide detailed images of soft tissue, such as the brain, spinal cord, and organs, which may not be visible on other imaging techniques like X-rays or CT scans. It is a non-invasive, painless procedure that does not use ionizing radiation.
How is an MRI performed?
The patient lies on a table that slides into the MRI machine, which looks like a large tube. The machine generates a strong magnetic field and radio waves, which create signals that are detected by a computer and turned into images.
Is MRI safe?
MRI is generally considered safe for most people, but there are some risks and precautions. People with certain medical devices, like pacemakers, may not be able to have an MRI. The strong magnetic field can also cause metal objects in the body to move or heat up, so patients need to remove all metal objects before the procedure.
What can I expect during an MRI?
During the MRI, the patient will need to lie still and may hear loud banging or knocking noises from the machine. Some patients may feel claustrophobic or anxious during the procedure, but the technologist can provide a panic button or sedative if needed.
How long does an MRI take?
The length of an MRI varies depending on the area being imaged, but most MRI scans take between 20 and 60 minutes.
Will I need to do anything to prepare for an MRI?
Depending on the area being imaged, patients may need to avoid eating or drinking before the procedure. They will also need to remove all metal objects, such as jewellery or hairpins, before entering the MRI machine.
How will I get my MRI results?
The images from the MRI will be reviewed by a radiologist, who will send a report to the patient's who will then discuss the results with the doctor.
