Method: In a case-control study, 26 male intravenous heroin addicts were selected from among non-treatment seeker abusing addicts in Tehran, and entered the study after a semi-structured interview and based on DSM-IV criteria. A demographic questionnaire and Addiction Severity Index were administered to all subjects before imaging. Each of the subjects underwent functional imaging with visual cue-induced craving, using functional magnetic resonance imaging (fMRI). Subjective reports of craving were evaluated after the imaging, using Visual Analog Scale (VAS). Also, 15 normal individuals with no history of drug abuse underwent fMRI as the control group. Blood-oxygen-level-dependent (BOLD) signal obtained during fMRI was analyzed using FSL. Results: There was a significant difference in brain activation between responder and non-responder groups (p %> http://ijpcp.iums.ac.ir/article-1-569-en.pdf %P 269-280 %& 269 %!
