Yes / This study aimed to determine whether a reduction in radiation dose was found for percutaneous
coronary interventional (PCI) patients using a cardiac interventional x-ray system with state-of-the-art image
enhancement and x-ray optimization, compared to the current generation x-ray system, and to determine
the corresponding impact on clinical image quality. Patient procedure dose area product (DAP) and fluoroscopy
duration of 131 PCI patient cases from each x-ray system were compared using a Wilcoxon test on median
values. Significant reductions in patient dose (p ≪ 0.001) were found for the new system with no significant
change in fluoroscopy duration (p ¼ 0.2); procedure DAP reduced by 64%, fluoroscopy DAP by 51%, and
“cine” acquisition DAP by 76%. The image quality of 15 patient angiograms from each x-ray system (30 total)
was scored by 75 clinical professionals on a continuous scale for the ability to determine the presence and
severity of stenotic lesions; image quality scores were analyzed using a two-sample t -test. Image quality
was reduced by 9% (p ≪ 0.01) for the new x-ray system. This demonstrates a substantial reduction in patient
dose, from acquisition more than fluoroscopy imaging, with slightly reduced image quality, for the new x-ray
system compared to the current generation system. / Philips Healthcare (the Netherlands)
