I am a 71 year old woman and i had an mri of my brain and the final report said "minor non-masslike t2 flair hyperintensities are seen within the deep cerebral white matter, compatible with mild chronic microanangiopathic changes." please explain?

Those findings are common in patients with history of hypertension or atherosclerotic vascular disease at your age. You only need to have systolic blood pressure less than 140 (for your age this systolic pressure is probably low enough, although there is still controversy between 130 vs 140) and LDL cholesterol less than 100, you will be fine.

Dr Kuitems agreed

Your outcome is rather typical for 71 yo folks, and rather nonspecific, as maybe consistent with arteriolosclerosis, but can be seen with hypertension, smoking, prior migraine, head trauma, and a number of other causes. Since you appear concerned, see your doctor and discuss potential clinical correlations and significance.
