Hello doctor,

I would like a radiologist to interpret my brain MRI. I am currently using tablet Metformin 500 mg twice daily.

Kindly interpret the scan and advise.

Thank you.



Welcome to

I have seen the MRI (magnetic resonance imaging) scan (attachments removed to protect patient's identity). It would have been more helpful if you mentioned what kind of health problems required you to get an MRI. However, the good news is that the MRI shows no abnormal findings except the DWI (Diffusion-weighted imaging) and ADC (Apparent diffusion coefficient) images show a wedge-shaped black area, but that is a technical artifact (T2 blackout) rather than an abnormality. So you can be rest assured about the MRI.

I hope this helps.

Do revert in case of further queries.

Thank you.

Best wishes.

Hello doctor,

Thank you for your response.

My previous CT scan showed Chiari malformation, and I was also tested for MS (Multiple Sclerosis).



Welcome back to

Thank you for updating us with your previous medical information. Yes, on the recent MRI, the point of Chiari is indeed noted as herniation of the cerebellar tonsils. However, there is no hydrocephalus in the brain or syrinx in the visualized part of the spinal cord. Your concerned doctor may suggest a whole spine MRI to check the rest of the spinal cord. Also, regarding suspicion of MS (Multiple Sclerosis), there is no lesion to support the diagnosis.

I hope you found this information helpful.

Do revert in case of further questions.

Best wishes.

Regarding follow up:

Follow up, if required.
