(Top) Longitudinal oblique grayscale ultrasound through the lower right abdomen shows the right psoas muscle, which originates from
the lumbar spine and inserts into the proximal femur. (Middle) Transverse grayscale ultrasound of right mid abdomen using the kidney
as an acoustic window is shown. The kidney is anterior and lateral to the psoas and anterior to the quadratus lumborum. The psoas runs
along the paravertebral region in its entire abdominal course. The quadratus lumborum originates from the iliolumbar ligament and
iliac crest to insert into the last rib and lumbar transverse processes. It is easily identified as the muscle on which the kidney rests.
(Bottom) Transverse grayscale ultrasound of the right upper abdomen, continuing the scan inferiorly shows the relationship of the
posterior abdominal wall muscles are maintained.
