Area of Science:

  • Interventional Radiology
  • Medical Imaging
  • Radiation Oncology

Background:

  • Uterine fibroid embolization (UFE) is a common procedure for treating uterine fibroids.
  • Minimizing patient radiation dose during interventional procedures is a critical aspect of patient safety.
  • Advancements in imaging technology are continuously sought to improve procedural efficiency and reduce radiation exposure.

Purpose of the Study:

  • To evaluate the effectiveness of an optimized angiographic processing and acquisition platform in reducing radiation dose during UFE.
  • To compare radiation dose metrics between a baseline imaging platform and an optimized platform in UFE procedures.

Main Methods:

  • Retrospective analysis of radiation dose data from 70 women undergoing UFE.
  • Comparison of data from 21 patients using a baseline platform versus 49 patients using an optimized platform.
  • Collection of cumulative kerma-area product (CKAP), cumulative air kerma (CAK), fluoroscopy time, and image counts; blinded qualitative image quality assessment.

Main Results:

  • The optimized platform resulted in a significant reduction in radiation dose indicators.
  • Mean CKAP decreased by 60% (438.5 to 175.2 Gy·cm²; P < .0001).
  • Mean CAK decreased by 45% (2,034.2 to 1,109.8 mGy; P = .001), with no degradation in image quality.

Conclusions:

  • An optimized image acquisition and processing platform can significantly reduce patient radiation dose during UFE.
  • The implementation of advanced imaging technology offers a viable strategy for dose reduction in interventional radiology.
  • This approach enhances patient safety without compromising diagnostic image quality.
