title: Coronary fractional flow reserve.
abstract: OBJECTIVE. This article presents the basic definitions and concepts of fractional flow reserve (FFR), a focused understanding of the need for hyperemia during assessment, key clinical studies supporting its use, and an introduction to newer noninvasive methods using FFR CT. CONCLUSION. Although it is still a new procedure, FFR CT may prove to be of tremendous use as the computational processing improves to reduce calculation times and enhance accuracy.
