Kastrati M, Langenbrink L, Piatkowski M, et al. Reducing Radiation Dose in Coronary Angiography and Angioplasty Using Image Noise Reduction Technology. Am J Cardiol. 2016 Aug 1;118(3):353-356.

This study sought to quantitatively evaluate the reduction of radiation dose in coronary angiography and angioplasty with the use of image noise reduction technology in a routine clinical setting. The dose area product was reduced from 3195 ± 2359 to 983 ± 972 cGycm2 (65%, p <0.001) in coronary angiograms and from 7123 ± 4551 to 2431 ± 1788 cGycm2 (69%, p <0.001) in coronary interventions using the new noise reduction technology. Image quality was graded as similar between the evaluated systems (4.0 ± 0.7 vs 4.2 ± 0.6, not significant).
