Fluoroscopy time is not accurate as a surrogate for radiation exposure

In plain language

In 145 lower extremity endovascular procedures, fluoroscopy time correlated poorly with air kerma and dose area product, suggesting it is a weak stand-in for radiation delivered; staff dose was not measured.

Summary based on
the abstract

What it found

  • Fluoroscopy time correlated poorly with total air kerma and dose area product.

    Key figures: r = 0.27 and 0.32

  • Total dose-area product (DAP) was strongly correlated with cine DAP and fluoroscopy DAP.

    Key figures: r = 0.92 vs. 0.84

  • Mean magnification level was significantly correlated with total air kerma.

    Key figures: r = 0.53

  • Number of digital subtraction angiography (DSA) runs and average frame rate did not affect air kerma (AK) or DAP.

  • Mean procedural air kerma and DAP for lower extremity endovascular interventions.

    Key figures: 380.27 mGy and 4919.2 µGym2

Limits to keep in mind

Single-center retrospective analysis of 145 lower extremity procedures on one C-arm system; measures patient-related dose indices only, not staff dose.

How this summary was made

ORSIF prepared this summary with AI assistance from the abstract of the paper. A program then checked that the passage supporting each finding appears word for word in that source. A person has not yet reviewed each summary, so read the original before relying on a number. ORSIF summarizes research and does not endorse any product or company.
