Summary based on

the abstract

What it found

• Patient dose (DAP and air kerma) was substantially lower with the novel image processing technology than with the reference system.

  Key figures: 43% (DAP) and 40% (AK) lower; P < .0001

• Operator dose was halved with the novel imaging technology.

  Key figures: 50% reduction; P < .001

• Fluoroscopy time, exposure frames and procedure duration were equivalent, suggesting image quality was similarly adequate.

• Procedural success was the same in both groups.

  Key figures: 91% in both groups

Limits to keep in mind

Single-center, unblinded trial with modest sample; operator dose was a secondary end-point, and the groups differed in age. Image quality was inferred indirectly from fluoroscopy time and frames rather than formally rated.
