Is it possible to get another answer on this qs. please. what does gliosis on a brain mri mean? a few scattered punctate foci of increased flow signal consistent with areas of gliosis are identified in the bilateral cerebral hemisphere?

By Radiopaedia.org: "gliosis is a reactive process occurring after some time following most types of central nervous system injuries and is the result of focal proliferation of glial cells, particularly astrocytes". So those findings are abnormal but no specific, the significance will depend on the medical history, symptoms, neurological signs and other laboratory findings.

Basically, "gliosis" is the brain's expression of scarring, and represents prior issues. The description is nonspecific but can indicate prior smoking, head injury, migraine, microvascular angiomatosis, prior encephalitis, hypertension, as a few examples. Discuss your correlations with your doctor.
