Hypointense
Hypointense is an MRI term describing tissue that appears darker than expected on a particular MRI sequence.
When to get help quickly: Urgency depends entirely on the underlying finding, not the dark signal itself.
Common symptoms
It is an imaging finding, not a symptom. The patient's symptoms come from the underlying condition.
When imaging helps
The meaning of hypointensity depends on the sequence — dark on T2 may suggest fibrosis, calcification, or chronic blood products; dark on T1 may suggest fluid or oedema.
What radiology does
Reading hypointensity requires the sequence, the pattern, and the clinical context together.
What usually happens next
Management is driven by what the dark signal represents — calcification, scar, old bleed, fibrosis, or something else.
