[|Human|] I have just had an MRI (brain)results came back :_no brainstem or cerebelar lesion.  Normal fourth ventricle.Small left centrum simovale area of hyperintensity on T2 weighted imaging is seen.  There are numerous hyperintense foci seen bilaterally in both cerebral hemispheres involving the frontal and parietal lobes.Am now being sent to have ultrasound on carotid arteries.  Can you explain in an easy term for me to understand
[|AI|]  Hi, Thank you for posting your query. Your MRI brain findings are suggestive of decreased blood flow to some parts of brain. Further tests are required to know whether there is narrowing of carotid arteries (and hence the Doppler ultrasound of the neck vessels). Also, risk factors such as sugar, BP and cholesterol should be checked. I hope it helps. Please get back if you require any additional information. Best wishes, Chat Doctor. Ly/
