HA filler can remain detectable on MRI years after injection. But a scan showing residual material does not, by itself, tell us whether it is still producing a visible volumising effect or whether it is causing harm.
The evidence needs careful interpretation. A small MRI study can show persistence in the people studied; it cannot tell us how common that is across all patients. Delayed local complications are recognised, but that is different from claiming that asymptomatic residual HA causes chronic systemic illness.
Patients deserve balanced information, proper assessment and decisions based on their individual circumstances, not panic based on an image alone.
What do you think: should MRI-visible filler automatically be treated as a problem?
