Summary based on

the abstract

What it found

• Simulated scatter doses at the cardiologist's eyes varied widely across paediatric procedures.

  Key figures: 0.20 to 116 µSv per procedure

• Cumulative patient entrance surface air kerma varied widely across simulated procedures.

  Key figures: 2 to 1100 mGy

• Kerma-area product values ranged widely.

  Key figures: 0.30 to 150 Gy cm(2)

• Large differences between X-ray systems were found, and the authors call for standardized system settings and protocols in Chile.

Limits to keep in mind

Doses were derived from PMMA phantom measurements combined with average fluoroscopy time and cine frame counts rather than measured on staff during real procedures. The abstract does not state the number of X-ray systems or hospitals.
