The imaging findings in intestinal ischemia depend on the stage of the condition and the timing of imaging. Figures 11 and 12
Fig 11: Imaging findings according to evolution of ischemia.
Fig 12: Schematic representation of findings according to evolution of ischemia.
An important differential diagnosis of mesenteric ischemia is the adynamic ileus, which is illustrate in figure 13
Fig 13: The adynamic ileus, an important differential for mesenteric ischemia.
The thickness and pattern of enhancement of the bowel wall can be a clue to the origin of the ischemia. "Paper-thin" wall suggests arterial etiology, while thickenned bowel favors venous origin, see figures 14 and 15
Fig 14: The bowel wall as an indicator of the origin of the ischemia.
Fig 15: Patterns of enhancement of bowel wall in mesenteric ischemia and respective meaning.
Indirect signs of the mesentric ischemia can be seen in the peritoneal cavity and mesenteric fat, as seen in figure 16
Fig 16: Extra-intestinal signs of mesenteric ischemia on CT images.
The response to the ischemia by the other abdominal organs may help to establish the diagnosis of bowel ischemia. These findings are summarized in figure 18
