Does MRI without contrast show chiari?

I can't remember if you need an MRI with contrast to see chiari? Or does the herniation measurement show just as well without contrast?

pretty sure they can see Chiari without contrast. I think the contrast helps when they are looking for blockage of the flow of spinal fluid.

My MRIs were both with and without contrast and my NS said the w/o MRI actually showed the Chiari more clearly.

I just saw this post but am going to respond to bump in case others have the same question. The answer is yes, I have never had a contrast MRI and each one since 2008 has shown the Chiari so clear that I can even measure it on the CD and I am not a doctor.

Recently had a spinal MRI and that too, was without contrast and measured the CM.

Hi All,

I have SM (no Chiari), but my initial diagnosis was made using an MRI without contrast.

I have had two subsequent MRIs - one with contrast, and one set both with and without contrast. The neurologist & neuro-radiologist told me that the contrast is helpful when they are trying to determine measurements and changes, since it makes what is being measured/compared more distinct.
