A 48-year-old woman with superior mesenteric artery syndrome. a Axial CT image on the arterial phase shows dilatation of the second portion of the duodenum (arrow), due to the compression of the third portion (arrowhead) between the abdominal aorta and the SMA. b Sagittal CT image of the abdomen shows gastric dilatation (arrowhead) caused by compression of the third portion of the duodenum between the abdominal aorta and the SMA (arrow). This sagittal reconstruction also allows measurement of aortomesenteric angle (17°) and aortomesenteric distance (6 mm), values diagnostic for mesenteric artery syndrome
