OBJECTIVE. Fractional flow reserve derived from coronary CT angiography (FFRCT) is an emerging tool for noninvasive evaluation of coronary artery disease that provides a combined anatomic and physiologic evaluation. The goal of this article is to serve as a review of the current status of FFRCT through discussion of existing trials on the modality and to introduce readers to examples of its utility and potential pitfalls. CONCLUSION. This article reviews the current body of evidence on FFRCT and provides case examples illustrating its current uses, limitations, and potential future applications.
