Why are MRIS bad for you?
The strong, static magnetic field of the MRI scanner will pull on magnetic materials and may cause unwanted movement of the medical device. The radiofrequency energy and magnetic fields that change with time may cause heating of the implanted medical device and the surrounding tissue, which could lead to burns.
How long does it take to get results of head MRI?
The radiographer will review and interpret the scans. They will then contact the doctor with the results. This can take several days unless it was an emergency scan. A person can request to see their scans by asking their doctor. The doctor may need a follow-up scan, and they will explain why.

What should I expect from a MRI scan?
Magnetic resonance imaging (MRI) scans provide 3-D images of specific body parts. The scan produces highly detailed images from every angle. Depending on the purpose of the scan, a doctor may recommend contrast, which is a substance that a person takes beforehand. It helps the images to be more clearly defined.
Why do you need a MRI of the head?
MRI scans use strong magnetic forces and radio waves to create images. They can scan bone, organs, and tissue, which makes them ideal for a complex body part like the head. MRI scans show a higher level of detail than other imaging techniques, especially in soft tissue. This is important when examining the brain or brain stem for damage or disease.
When do you need a second MRI scan?
Sometimes you need a second scan because the consultant radiologist wants to add some contrast to show up different pathologies. It’s very frustrating to have to go back , but best to have a full screen and proper diagnosis.
What happens if you have a normal MRI?

Why did I have a brain scan last week?
