(Top) Longitudinal grayscale ultrasound of the right lobe of the liver shows the liver ends just above the inferior margin of the right
kidney. Normal hepatic length should be < 15-15.5 cm. Notice that the normal hepatic parenchyma is slightly hyperechoic compared to
the normal kidney. (Middle) Transverse high-resolution ultrasound of the liver capsule, as seen here, is typically obtained with higher
frequencies (7-9 MHz). Subtle nodularity of the capsule and small subcapsular liver lesions that may not be as well visualized with
standard (3-5 MHz) frequencies are best visualized with this view. Note the hepatic veins have no discernible wall, whereas the portal
veins have slightly echogenic walls. (Bottom) Longitudinal oblique ultrasound shows a normal gallbladder with anechoic fluid within
the lumen and normal appearance of the gallbladder wall. Normal gallbladder wall thickness should be measured at the interface with
the liver and should be less than 3 mm in thickness. A fold in the gallbladder neck is incidentally seen in this patient.
