Dual-bolus
first pass MR myocardial perfusion imaging has been shown to compensate for
signal saturation in arterial input function, and resulted into more
realistic perfusion values. We investigated whether this dual bolus approach
also improved diagnostic value for the detection of significant coronary
artery disease (CAD). In 49 patients with suspected CAD adenosine stress and
rest MR perfusion imaging was performed with single and dual bolus imaging.
Invasive coronary angiography was used as standard of reference. Dual bolus
imaging showed lower perfusion values, but ROC analysis showed no incremental
diagnostic value over single bolus technique for detection of significant
CAD.
