US researchers have found a way to predict how successful a smoker will be at quitting by using an MRI scan to look for activity in a region of the brain associated with behavior change.

The scans were performed on 28 heavy smokers who had joined an anti-smoking program, according to the study published in the journal Health Psychology.

Participants were asked to watch a series of commercials about quitting smoking while a magnetic resonance imaging machine scanned their brains for activity.

After each ad, subjects in the study "rated how it affected their intention to quit”, researchers explained.

Those who showed activity in the medial prefrontal cortex during the ads were "significantly linked to reductions in smoking behavior" in the month that followed, regardless of how the people said they were affected by the ad.

Lead researcher Emily Falk said researchers would next try to determine which kinds of messages were most effective by matching brain activity to the ads.

The study was funded by the US National Institutes of Health and the National Science Foundation.
