Image-based 3D Fusion CT Decreases Rad. Exposure. Southerland et.al

Objective

Although endovascular aneurysm repair (EVAR) has minimal perioperative morbidity and mortality, it is still associated with increased radiation exposure and contrast material use. Three-dimensional (3D) fusion computed tomography (CT) technology has the potential to revolutionize endovascular management of aneurysms by mitigating radiation exposure. Currently available 3D fusion devices use hardware-based (ie, operating table) tracking to position the overlay on the fluoroscopic image. This can be labor-intensive and lead to inaccurate overlay. Recently, our institution implemented a novel cloud-based 3D fusion system, which has been shown in prior studies to be highly accurate. This system uses the patient’s vertebral anatomy rather than the operating table to register and produce the overlay, and it can be used with any imaging system, including C arm. The purpose of this study was to investigate the impact of this new 3D fusion system on EVAR.
