Kidneys Right hemidiaphragm RIGHT KIDNEY, CT CORRELATION Right lobe of liver Anatomy: Abdomen Renal cortex Pelvicalyceal system Renal medullary pyramids Gallbladder Right lobe of liver Right kidney Right main renal vein Gallbladder Perinephric fat Right psoas muscle Right hemidiaphragm Right lobe of liver Right portal vein Right kidney (Top) Correlative longitudinal CT multiplanar reconstruction image of the right kidney through planes that are commonly used when examining the patient with ultrasound. Like ultrasound, multidetector row CT now allows evaluation of kidneys in many planes; however, ionizing radiation and the use of intravenous contrast are its limiting factors, particularly in children. (Middle) Correlative longitudinal oblique CT multiplanar reconstruction image of the right kidney cutting through the right renal vein is shown. The plane of this image is angulated more medially when compared with the previous image. (Bottom) Correlative longitudinal oblique CT multiplanar reconstruction image of the right kidney cutting through the right portal vein with the plane of this image is angulated more laterally when compared with the previous 2 images. 51

Kidneys Anatomy: Abdomen RIGHT KIDNEY, ANTERIOR ABDOMEN SCAN Subcutaneous fat Gallbladder Right lobe of liver Head of pancreas Inferior vena cava Right kidney Aorta Subcutaneous fat Right lobe of liver Duodenum Pyramid Right renal artery Pancreas Aorta Inferior vena cava Vertebra Subcutaneous fat Right lobe of liver Shadowing from rib Bowel gas Right kidney (Top) Transverse grayscale ultrasound of the upper pole of the right kidney is shown. (Middle) Transverse grayscale ultrasound of the mid pole of the right kidney shows the renal hilum with the renal vein. Note that the pelvicalyceal system within the renal sinus echoes is not usually visible in the normal individual. (Bottom) Transverse grayscale ultrasound of the lower pole of the right kidney. The renal parenchymal echogenicity is less than the adjacent liver or spleen. If the renal parenchyma is brighter than normal liver, renal parenchymal disease should be suspected. 52
