The Use of Perfusion CT Derived Parameters as Early Acute Pancreatitis Severity Biomarker Compared to Clinico Biological Score

The Use of Perfusion CT Derived Parameters as Early Acute Pancreatitis Severity Biomarker Compared to Clinico Biological Score

The investigators to establish whether early microvascular permeability parameter evaluated by perfusion-CT could be good biomarkers for severity in acute pancreatitis.

Therefore the investigators want to compare 48 hours-clinico-biological systemic inflammatory response syndrome score to initial microvascular permeability parameters ( ktrans - capillary membrane permeability factor- and pancreatic blood flow ) calculated by OLEA software using inclusion perfusion CT.

Inclusion Criteria:

• Patient with acute pancreatitis (based on the Atlanta definition).

Exclusion Criteria:

• Patient under 18 yearras old
