Zusammenfassung
Purpose:The aims of this study were 1) to evaluate the feasibility and accuracy of standard GRE and myocardial tagging for detection of obstructive CAD in a high dose dobutamine stress protocol and 2) to investigate the additive value of myocardial tagging in a combined standard cine GRE & tagging stress protocol at 3 Tesla. Materials and Methods: Patients with known or suspected CAD were included. The study protocol was approved by the local ethics committee. A standard high dose dobutamine protocol was employed with incremental doses of dobutamine (10µg/kg up to 40µg/kg) and eventually fractionated atropine (u…
