Abstract
Dual-energy CT (DECT) has been available for clinical use in the United States for close to 15 years. Although multiple applications in all areas of the body have been described that are only possible with DECT, the adoption into clinical practice has been slow. This paper will attempt to address many of the impediments the author has encountered from his discussions with radiologists across the country. A hopeful outcome would result in more practices adopting more DECT into their CT practices.
