Reduced Patient Radiation Exposure during Neurodiagnostic and Interventional X-Ray Angiography with a New Imaging...

Area of Science:

• Medical Imaging
• Neurosurgery
• Radiology

Background:

• Endovascular treatments for cerebrovascular diseases are increasing.
• Concerns exist regarding radiation exposure for patients and operators.
• Advanced imaging technology aims to mitigate these risks.

Purpose of the Study:

• To evaluate patient radiation doses using an advanced x-ray imaging platform with dose-reduction technology.
• To compare radiation doses from the new platform against a reference platform.
• To assess the impact of dose-reduction technology on workflow and contrast volume.

Main Methods:

• A retrospective study compared 1238 neurointerventional cases on a dose-reduction platform versus a reference platform.
• Cumulative dose-area product, fluoroscopy duration, and contrast volume were analyzed.
• Statistical analyses accounted for patient characteristics and the neurointerventional radiologist.

Main Results:

• The dose-reduction platform achieved a 53.2% reduction in cumulative dose-area product (160.3 Gy × cm²).
• Fluoroscopy duration increased slightly (5.2 minutes), and contrast volume increased non-significantly (15.3 mL).
• These changes were statistically significant for dose reduction and marginally significant for fluoroscopy duration.

Conclusions:

• Dose-reduction technology significantly reduces patient radiation dose in neurovascular procedures.
• This technology offers substantial radiation safety benefits.
• The observed impact on workflow and contrast use is minimal.
