In plain language
In a small retrospective study of standard endovascular aneurysm repair (EVAR), 3D image fusion roadmapping was associated with about 40% lower air kerma, shorter fluoroscopy and procedure times, and less contrast. Staff dose was not measured directly.

What it found
Air kerma was lower with VesselNavigator 3D image fusion than with conventional imaging in EVAR.
Key figures: 1067 ± 470.4 mGy vs 1768 ± 696.2 mGy; P = .004
Fluoroscopy time was shorter with image fusion.
Key figures: 18.4 ± 6.8 minutes vs 26.8 ± 10.0 minutes; P = .01
Contrast agent dose was roughly halved with image fusion.
Key figures: 37.4 ± 21.3 mL vs 77.3 ± 23.0 mL; P < .001
Procedure time was shorter with image fusion.
Key figures: 80.4 ± 21.2 minutes vs 110.0 ± 29.1 minutes; P = .005
Limits to keep in mind
Small single-institution retrospective comparison of 16 body mass index (BMI)-matched patients per group, with possible learning-curve and selection bias. Only patient air kerma was measured; reduction in provider exposure is inferred, not measured.
