*7.3.1. Color Doppler Ultrasound*

It is the initial imaging technique for control and monitoring of pancreas transplantation. The study with electronic data capture (EDC) allows to assess the size and the structure of the graft, the presence of liquid collections (study in B mode), and the perfusion of the parenchyma (resistance index), as well as the permeability of the vascular anastomoses (Doppler study). An extension of the study can also be done with the ultrasound signal enhancer, if it is considered appropriate by the sonographer who performs the study. It is advisable to make a basal study, between 24 and 48 h post-transplant, and a follow-up study, every 3–4 days until the patient's discharge.
