The book concludes with two chapters focused on future hopes for the field of neuroimaging in addiction. The first discusses the intersection of genetics and imaging and reviews some early studies, while also outlining potential obstacles. The final chapter of the text, titled “the Diagnostic and Therapeutic Potential of Neuroimaging in Addiction Medicine,” highlights one of the main future goals for the field. As outlined in chapter 1, while the advances in neuroimaging methodologies have been rapid, they have sprinted ahead of the clinical application in addictions treatment, and early hopes that imaging would quickly have a major effect on addiction medicine have gone, as yet, unrealized. The field, therefore, continues to rely on “descriptive, symptomatic checklist criteria” for diagnosis. In the final chapter of the text, the authors outline early research showing some utility of imaging procedures in predicting prognosis and discuss the hope that imaging techniques may one day be brought to the bedside in addiction treatment, allowing clinicians to predict risk for development of later substance dependence problems, to more accurately and objectively diagnose, to select individualized treatments, to monitor treatment progress, or perhaps even to conduct neurofeedback. Despite the promise of addiction research and progress in understanding the neurobiology of addiction, this is not a treatment text. This underscores the progress still needed in the field.
