Hello dr, i had a mri of my brain. it came back as slight chronic microvascular ischemic changes. what does that mean? also what does a air cell mean?

Aging changes: As we get older, arteries harden and we see small vessel changes in the brain due to aging. They simply mean the brain doesn't work as well as it did when we are young and mostly attest to our slowly diminishing function. These are microvascular ischemic changes. You probably don't notice these changes. Air cells are bony areas of the skull with air spaces in them- normal.

Nonspecific: The radiologist mentioned "microvascular" ischemic changes as correlation to appearance of white matter lesions, but these are truly nonspecific, and can be seen with many situations: smoking, hypertension, prior head injury, migraine, etc., besides expected arteriosclerosis. These should not be construed as indicative of ongoing disease in absence of clinical correlation.
