Abstract

AIMS: Quantitative stress perfusion (QP) cardiac magnetic resonance (CMR) can be performed using the dual sequence (DS) or dual bolus (DB) technique. DS does not require additional contrast and image acquisition but needs a research sequence. DB can be performed on all magnetic resonance imaging (MRI) scanners with standard perfusion sequences but requires additional contrast injection and image a…
