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.
