In Reply We thank Baumann et al for their letter regarding our review1 and welcome the inclusion of more data to define the diagnostic performance of computed tomography–derived fractional flow reserve (FFR-CT). We agree with our colleagues that this novel technique is rapidly evolving and, like any new technology, will aspire to increase processing speed2 and accuracy with successive iterations of the product.
