Significant Radiation Dose Reduction in the Hybrid Operating Room Using a Novel X-ray Imaging Technology

Area of Science:

• Medical Imaging
• Radiology
• Cardiovascular Surgery

Background:

• Hybrid operating rooms (OR) integrate advanced imaging with surgical facilities.
• Minimizing radiation exposure for patients and staff is crucial in interventional radiology.
• Aortoiliac endovascular procedures require precise imaging guidance.

Purpose of the Study:

• To quantify radiation dose changes in aortoiliac endovascular procedures using novel X-ray imaging technology.
• To assess the impact of this new technology on patient and staff radiation dose.
• To evaluate any effects on procedure time, fluoroscopy duration, and contrast medium administration.

Main Methods:

• Prospective study of 138 patients undergoing EVAR or AIOD procedures.
• Comparison of radiation dose (Air Kerma, Dose Area Product) before and after implementing new X-ray imaging technology (ClarityIQ).
• Real-time personal dosimetry for staff radiation measurements; recording of procedural data.

Main Results:

• Significant patient radiation dose reduction: 56% in EVAR and 76% in AIOD (median AK).
• Significant staff radiation dose reduction: 16% in EVAR and 69% in AIOD.
• No statistically significant differences observed in procedure time, fluoroscopy time, or contrast medium use.

Conclusions:

• The novel X-ray imaging technology substantially reduces patient and staff radiation doses in hybrid OR settings.
• This technology allows for significant dose reduction without compromising procedural efficiency or contrast agent administration.
• The ClarityIQ technology represents a valuable advancement for radiation safety in endovascular interventions.
