This study evaluates visual scores of image quality (conspicuity, artifact, noise; Likert scale 1[worst]-5[best], 3 acceptable) produced by a wideband cardiac perfusion sequence in patients with CIED and a standard sequence in matching non-device patients in the setting of vasodilated stress perfusion imaging. The median conspicuity scores were not significantly different between wideband (4) and standard (4). While the median artifact score was significantly worse for wideband (4) than standard (5), it was above the acceptable cutoff. The median noise score was significantly better for wideband than standard. Our wideband perfusion sequence produces diagnostically acceptable image quality in CIED patients.
