Figure 2b. Typical CT angiographic appearance of AA: phase 1—diagnosis. The patient was a 49-year-old man who was experiencing characteristic cramping abdominal pain after meals. (a) Multi-detector row CT angiogram shows a mildly stenotic celiac trunk and a high-grade atherosclerotic obstruction of the SMA. The IMA is not seen. (b) Digital subtraction angiogram (DSA) helps confirm the findings at multi-detector row CT. (c-f) Curved multiplanar reformatted (MPR) images obtained along the celiac trunk (c, d) and SMA (e, f) clearly demonstrate the extent of stenotic disease.
