In plain language

A pooled analysis of 11 studies found rotational coronary angiography used less contrast and lower patient radiation dose metrics than conventional angiography, with similar procedure time. Staff dose was not measured, though lower patient dose generally lowers scatter to the fluoroscopy team.

Summary based on
the abstract

What it found

  • Rotational angiography was associated with significantly lower contrast volume, dose area product and air kerma than conventional coronary angiography.

  • Fluoroscopy time was statistically but not clinically significantly longer with rotational angiography; procedure time did not differ.

  • Pooled analysis included 11 studies with 940 rotational and 976 conventional angiography patients.

    Key figures: 11 studies; 940 RA and 976 CA patients

Limits to keep in mind

Abstract only, with no pooled effect sizes reported. Dose metrics are patient-side measures, and staff dose was not measured.

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.
