I’ve Just Had An MRI Scan And I’ve Got A Pain In My Foot

I will try and use the AI functions of Google to make some sense of the title of this post.

These are the questions I asked.

Why Is My Left Foot Painful After An MRI Scan Of My Brain?

Google gave this AI Overview.

A foot pain after a brain MRI is likely unrelated to the scan itself. MRI scans are not known to cause pain in extremities, though some patients may experience temporary discomfort from having to lie still for an extended period. It’s more probable that the pain is coincidental, or due to another underlying issue unrelated to the MRI, such as a pre-existing condition or new injury.

Note.

1. It is a hot day.
2. I did a fair bit of walking to get to and from the MRI Scan.
3. I don’t think it was lying still for an extended period.
4. I felt a bit dehydrated after the scan.

Overall, my left foot is occasionally in pain and red. Certainly more often than my right! It doesn’t appear to be red today.

Can An MRI Scan Make You Dehydrated?

Google gave this AI Overview.

While MRI scans themselves don’t cause dehydration, staying well-hydrated is important, especially if contrast dye is used. Drinking plenty of fluids after an MRI with contrast helps flush the dye out of your system. Though dehydration can occur naturally, it’s not a direct effect of the MRI itself.

I didn’t have any dye.

But I was desperate for a drink, so I went into the first cafe, that I passed and had a coffee and cake.

Can An MRI Scan Stimulate Blood Flow?

Google gave this AI Overview.

While MRI machines don’t directly stimulate blood flow in the sense of causing it to increase, they can visualize and measure blood flow. Functional MRI (fMRI) specifically detects changes in blood flow related to brain activity as the brain uses more oxygen in active areas, leading to increased blood flow to those areas. Standard MRI can also be used to visualize blood vessels and assess blood flow, but it doesn’t directly cause the flow to change.

As I have now changed my shoes and socks to my slippers and the pain has disappeared, I suspect it was the new shoes.

I wrote this post, to show the quality of the answers of artificial intelligence to simple medical questions.

From my knowledge of data analysis, I suspect there’s much more to come with medical diagnosis using AI. Especially, if you login to a medical diagnosis computer system, that has details of your medical history.

I always remember my first B12 injection, after I had been diagnosed with coeliac disease.
