A technique for determining pump injector settings for an on-table CT or 3D DSA in interventional radiology

Hoddes, R; England, A

Abstract

Introduction
On-Table computed tomography (CT) or 3D digital subtraction angiography (DSA) in interventional radiology (IR) has become a valuable diagnostic tool.

Methods
A review of the literature found a poor evidential base supporting the technical parameters for iodinated contrast delivery during these acquisition sequences.

Results and conclusion
This technical note presents an easy method of estimating the parameters needed to reliably obtain diagnostic on-table CT or 3D DSA images, whilst attempting minimising contrast dose.

Implications for practice
A systematic approach to estimating contrast delivery regimes during on-table CT and 3D DSA can help ensure diagnostic quality images are obtained. Further clinical studies are now required to rigorously evaluate this protocol.
