Purpose

Acute pancreatitis and its complications can be a potentially life threatening condition. Accurate staging of the disease severity can significantly improve treatment and reduce patient mortality due to possible multiple organ failure (MOF)[1-3].

Dual energy CT (DECT) acquires data from two different X-ray beam levels, usually low energy at 80 kVp and high energy at 140 kVp and due to corresponding differences of absorption characteristics allows material decomposition analysis [4]. Iodine extraction enables generation of virtual non-contrast (VNC) images and iodine selective images which can be displayed using specific post-processing software and allowing both subjective and quantitative assessment of enhancement (Figure 1-3).

Contrast CT is a gold standard in staging of acute pancreatitis and detection of complications, but the aim of our study was to assess whether it can be upgraded by using DECT, especially in early or mild pancreatitis.
