Dynamic Contrast Enhancement Computed Tomography Based Technic to Assess Gastro Intestinal Wall Perfusion : Feasibility Study

This feasibility study has therefore several aims:

1. construct a dedicated CT perfusion protocol for GIT wall perfusion;
2. used a two-compartment pharmacokinetic model which is more adapted that a unique compartment model;
3. from the image acquired, evaluate current parameters of perfusion including the permeability ones

Inclusion Criteria:

• all patients over fifty years old with clinico-biological suspicion for acute GITischemia admitted at our institution

Exclusion Criteria:

• contra-indication to contrast agent injection as so defined by the European Society of UroRadiology in 2014
• inability to provide informed consent
