Researchers question FFR-CT’s value compared to other cardiac imaging options

An example of HeartFlow's FFR-CT technology, which takes the cardiac CT dataset and uses computational fluid dynamics to create virtual fraction flow reserve values. The FFR measurement can help determine if a coronary lesion is significant enough to require revascularization, or if the patient should be treated with medication. FFR-CT was included as a recommendation in select patients in the 2021 Chest Pain Guidelines.

FFR-CT has grown in popularity due its ability to provide noninvasive evaluations of patients being considered for revascularization procedures. According to a new study in JACC: Cardiovascular Imaging, however, stress imaging strategies may still provide more value in certain scenarios.
