Obligatory medical device diagnostics.
- Abdominal ultrasonography (ultrasonography of abdominal organs) [is not appropriate as a method of investigation in intestinal ischemia].
- X-ray abdominal survey [rapid detection (finding) of free air, thus a valuable differential diagnostic clue → hollow organ perforation]
- Computed tomography (CT) of the abdomen (abdominal CT) or CT angiography – showing blood vessels.
- Biphasic contrast CT with multiplane reconstruction (MPR) in three planes or multislice CT (multislice CT) [first-line diagnostics] – when acute occlusive mesenteric ischemia is suspected (performing an arterial and venous phase; the latter is necessary to diagnose mesenteric vein thrombosis)
- Catheter angiography (digital subtraction angiography (DSA) with i.a. infusion of vasodilators) – if non-occlusive mesenteric ischemia is suspected.
