We used functional magnetic resonance imaging(MMT) to
investigate the neural basis of the length effects of
long-term methadone maintenance treatment on brain
response to heroin-related cues in former
heroin-dependent individuals. Fifteen patients (duration
of MMT 1 year, group A) , fifteen matched patients
(duration of MMT 2-3 years, group B) and 17 healthy
controls were included. The self-reported heroin craving
score demonstrated no significant difference between
Group A and B. Compared with Group B, Group A
demonstrated greater activation in caudate when exposed
to drug-related cue. Long-term MMT may improve the brain
craving response by regulating the impaired function of
caudate.
