(Top) Transverse oblique ultrasound through the right iliac fossa (RIF) with graded compression shows a compressed, normal terminal
ileum (between the abdominal wall musculature anteriorly and psoas muscle posteriorly) leading to the cecum. (Middle) Transverse
high-resolution ultrasound through the RIF in the same patient shows the ileocecal junction and the ileocecal valve. (Bottom)
Transverse ultrasound through the left iliac fossa (LIF) shows a short-axis view of the descending colon with gut signature. Medial to
the descending colon, normal jejunal loops can be seen with valvulae conniventes.
