Magnetic resonance imaging (MRI) of the brain is a safe and painless test that uses a magnetic field and radio waves to produce detailed images of the brain and the brain stem. An MRI differs from a CAT scan (also called a CT scan or a computed axial tomography scan) because it does not use radiation.

Why did my MRI hurt?

MRI is a very safe procedure. The strong magnetic field itself does not hurt people, unless they have certain types of metal implanted in their body. The magnetic field can cause certain types of metal to move, which could potentially cause an injury.

Why do I feel weird after an MRI?

According to researchers at John’s Hopkins University, the magnet in MRI machines can stimulate the inner ear’s balance center, causing some patients to feel vertigo while they are inside the machine and in the minute or two after they’ve left it.

Can you wear a bra during an MRI?

For women, if possible, do not wear an underwire bra (the metal can throw off the magnetic field). Sports bras are usually good and we have hospital gowns to change into if necessary. The clasps on the back of a regular bra are not a problem, but avoid wearing bras that have metal parts on the straps.

She began her presentation by stating that “one of the most important problems in magnetic resonance imaging is motion.” When patients move during an MRI, they create motion artifacts in magnetic resonance images that often appear as ghosting artifacts, obscuring clinical information.

How long does gadolinium stay in the body?

With normal kidney function, most of the gadolinium is removed from your body in the urine within 24 hours. If you have acute renal failure or severe chronic kidney disease and receive a gadolinium-based contrast agent, there may be a very small risk of developing a rare condition.
