To compare pediatric procedural doses when using a reference technology (Allura Xper, Philips Healthcare) and a novel advanced image processing and dose reduction technology (AlluraClarity, Philips Healthcare) interventional radiology systems.

Radiation dose structured reports were retrospectively collected from 408 clinical pediatric cases; half performed with the reference and half with the novel X-ray technology. Dose-area product and fluoroscopy time were collected to compare procedural radiation dose. Procedural dose is defined as the total dose excluding any volumetric acquisitions (i.e. 3D rotational or cone beam CT).

180 and 175 patients underwent procedures with the reference and the novel technology, respectively. The 21 different procedure types covered a wide spectrum of pediatric interventional procedures yielding a total number of 204 procedures with each technology. The observed median ages of 12.6 and 11.6 years for the reference and the novel technology, respectively were not statistically different. No statistical difference in age distribution for both groups was observed. Weight and body mass index for both groups were not statistically different in median and distribution with medians being 36 vs 39 kg and 18.3 vs 18.2 kg/m2 for reference vs novel technology. Fluoroscopy time per procedure (median of 1.6 and 1.5 min for reference and novel technology respectively) and total recorded images (median of 2 frames per procedure) had statistically similar median, variance, and distribution for both groups. Procedural dose was significantly decreased from reference to novel X-ray imaging technology yielding a radiation dose 35% of its original value (1090 vs 385 mGy.cm2, p<0.0001). The fluoroscopy and fluorography acquisitions with the novel X-ray technology delivered 37% and 30% of the dose, respectively, of the reference technology.

With the novel advanced image processing and dose reduction technology, radiation dose of pediatric interventional procedures was reduced to 35% of its original value.

Pediatric Interventional Radiology procedural dose is significantly decreased with AlluraClarity, a novel advanced image processing and dose reduction technology.
