Socioeconomic Factors in Brain Research: Increasing Sample Representativeness with Portable MRI.

Abstract

People of low socioeconomic status (SES) are often underrepresented in biomedical research. The importance of demographically diverse research samples is widely recognized, especially given socioeconomic disparities in health, but have been challenging to achieve. One barrier to research participation by low SES individuals is their distance from research centers and the difficulty of traveling. This article examines the promise of portable magnetic resonance imaging (pMRI) for enrolling participants of diverse SES in structural neuroimaging studies, and anticipates some of the challenges, practical and ethical, that may arise in the course of such research.
