Rotational angiography: the effect of different contrast doses on visibility of anatomical structures

Satisfactory imaging facilities are mandatory to make relevant measurements to support endovascular aortic repair (EVAR). Rotational angiography with flat panel technology is a relatively new imaging modality with an additional functionality that enables creation of Computer Tomography (CT)-like slice images. We have tested the impact of two different contrast injection protocols on image quality in EVAR procedures. Our experience indicates that a sufficient dose of contrast medium has a significant impact on the evaluation that is needed to plan and carry out EVAR. A larger volume of diluted contrast medium significantly increases the visualisation of the distal arteries.
