Administering oxygen before hepatic digital subtraction angiography (DSA) significantly reduces motion artifacts. This simple intervention improves image quality in delayed-phase imaging.

Area of Science:

  • Medical Imaging
  • Radiology
  • Cardiovascular Imaging

Background:

  • Diaphragmatic motion artifacts can degrade image quality in hepatic digital subtraction angiography (DSA).
  • These artifacts pose a challenge for accurate interpretation of delayed-phase imaging.
  • Minimizing motion-related artifacts is crucial for diagnostic clarity.

Purpose of the Study:

  • To investigate the efficacy of oxygen administration in mitigating diaphragmatic motion artifacts during hepatic DSA.
  • To determine if supplemental oxygen can improve image quality in the delayed phase of hepatic angiography.

Main Methods:

  • The study involved patients undergoing delayed-phase hepatic digital subtraction angiography (DSA).
  • Oxygen was administered to a group of patients prior to the examination.

  • Image quality, specifically the presence of motion artifacts, was assessed.

    • Main Results:

    • Administration of oxygen prior to hepatic DSA substantially reduced motion artifacts.
    • Improved image clarity was observed in the delayed phase of angiography for patients receiving oxygen.
    • Oxygen appears to stabilize diaphragmatic movement during the scan.

    Conclusions:

    • Supplemental oxygen is an effective method for reducing diaphragmatic motion artifacts in hepatic DSA.
    • This technique offers a simple and practical approach to enhance image quality in angiography.
    • The findings suggest routine use of oxygen in relevant DSA procedures to improve diagnostic accuracy.
