Video 12-01: Normal kidney longitudinal image
This longitudinal view of the kidney demonstrates the white perinephric fat surrounding the darker cortex of the kidney. In the center is the hyperechoic renal pelvis, which is brighter due to the fat. The operator is fanning through the kidney to give a full view. Also visible are rib shadows, spleen, and some bowel gas. The operator is carefully adjusting the angle of the transducer to maximize the window between the ribs.
