Will an MRI show an aneurysm in the brain?

They both work and give different information and both have their risks. X-rays are not one of the risks. This is the only time I will answer on this thread.

That contrast dye is hard on your kidneys. Careful there if you already have issues.

Yes, an MRI of the brain can show aneurysms. MRI scans use strong magnetic fields to create detailed images of the brain, allowing doctors to determine the size, shape, and location of aneurysms. These scans can be valuable in detecting blood vessel abnormalities and the anatomy of aneurysms and other vascular lesions.

A CT can also.

If they want to do a dye scan, ask them to check your BUN and creatinine first to make sure your kidneys aren’t already compromised. They should automatically check but a reminder never hurts.

That’s why she doesn’t want the dye, her kidneys.

She can minimize any effects by drinking lot of water, plus they’ve tweaked the dye formula to minimize effects. If her labs are screwy they won’t do the dye; if they’re ok, it means the kidneys can handle the dye safely. It’s usually eliminated within 24 hours if I remember right.

Unless she has a reaction to the dye.
