(Top) Transverse subxiphoid grayscale ultrasound shows the left renal artery coursing posterior to the superior mesenteric artery and
splenic vein as it descends to enter the left renal hilum. (Middle) Transverse subxiphoid color Doppler ultrasound is shown. This image
was taken with a small amount of cranial tilt so that blue indicates flow toward the transducer and red away from the transducer. Note
therefore that aortic flow is blue and IVC flow is red. The splenic vein is red in its proximal portion but exhibits blue color distally, owing
to its course. The left renal artery is almost at right angles to the transducer and therefore flow is not well seen. (Bottom) Transverse
subxiphoid power Doppler ultrasound demonstrates the vessels posterior to the pancreas. Power Doppler is more sensitive for detecting
vascular flow but fails to provide information on flow direction.
