Abstract:
Variations in radiation dose between various X‐ray systems have received limited study. Objective We examined the impact of X‐ray system type on patient radiation dose during cardiac catheterization. Methods An anthropomorphic phantom was used in a series of standardized experiments that involved 15 sec of continuous cineangiography in 7 projections. Three to seven experiments were performed in four commonly used X‐ray systems: Innova IGS (GE Healthcare), Integris Allura FD20 (Philips), Allura Clarity (Philips), and Artis one (Siemens). Phantom radiation dose was measured with a dedicated X‐ray dosimetry system (Gafchromic radiology film and Film QA XR software, Ashland) that was precalibrated at 0, 1, 2, 3, and 4 Gray, and with the X‐ray system built‐in functions. Results Radiation dose was lowest with the Allura Clarity system [average film dose 4.2 ± 0.1 cGray, peak film dose 18.3 ± 1.6 cGray, Air Kerma (AK) dose 0.310 ± 0.002 Gray, Dose Area Product (DAP) dose 23.72 ± 0.84 Gray*cm 2 ], intermediate with the Integris Allura FD20 (average film dose 4.4 ± 1.1 cGray, peak film dose 29.4 ± 15.5 cGray, AK 0.482 ± 0.189 Gray, DAP 45.18 ± 21.90 Gray*cm 2 ), and highest with the Artis one system (average film dose 7.4 ± 0.8 cGray, peak film dose 66.9 ± 0.09 cGray, AK 0.746 ± 0.085 Gray, DAP 75.93 ± 9.11 Gray*cm 2 ) and the Innova IGS system (average film dose 7.2 ± 1.0 cGray, peak film dose 49.3 ± 28.9 cGray, AK 0.874 ± 0.340 Gray, DAP 92.28 ± 14.73 Gray*cm 2 ; P = 0.011 for average film dose, P = 0.019 for maximum film dose, P = 0.033 for AK, and P = 0.008 for DAP). Conclusions The X‐ray system type has significant impact on patient radiation dose during cardiac catheterization. © 2015 Wiley Periodicals, Inc.
