Evaluation of different contrast medium injection techniques in the Angio-CT study of the lower limbs in patients with obliterating arteriopathy

The need to write this article was born with the aim of optimizing the Angio-CT study protocol of the lower limbs, comparing two Mdc injection techniques: standard and split bolus, performing a parameter check vital collected before and during injection of the Mdc in order to establish the plateau between reaching the peak of enhancement during the smartprep and the start of the scan. Then well defined parameters are assigned for the evaluation of the images obtained with the different techniques.In the study the inclusion or exclusion parameters of the patient are defined, recruiting 133 cases.The Split Bolus injection technique is optimal together with an accurate evaluation of the patient's vital parameters. Although appreciating the excellent results, the limits of this study are also described.
