Emerging techniques: Whole‐body screening and staging with MRI

Abstract

Strategies for screening or tumor staging include various modalities such as plain radiography, computed tomography (CT), MRI, and ultrasound. Technical innovations have created the feasibility to use MRI to image the entire body in a relatively short time‐period. Whole‐body MRI may play a potentially important role in evaluating for cancer or vascular disease. This article describes the rationale for using MRI to display the entire body, the techniques employed in whole‐body MRI, possibilities and limitations, and summarizes first clinical results for screening and staging purposes.
