Resumo
Objective: We proposed and tested a novel acquisition protocol for optimizing a fast computed tomography angiography using a 160-row detector scanner using a longer contrast injection time coupled with multiphasic rate of injection. Methods: A prospective randomized study was performed to compare image quality, contrast enhancement, and radiation dose in 2 groups ( a fast acquisition and a widely accepted slow acquisition). Results: There was no difference between groups regarding image quality, noise, and diagnostic performance, but we evidenced a trend to higher radiation dose for the fast acquisition protocol. Conclusions: An optimized protocol for performing a fast acquisition computed tomography angiography of lower limbs is feasible, has sufficient diagnostic quality, and can be used in selected patients who would benefit from a short-time scan.
