3. • Fig GI 71-1 Acute hepatitis. (A) Longitudinal
and (B) transverse scans of the right lobe in
two different patients show an overall
decrease in the echo pattern. Note that the
portal vein radicle walls (arrows) are brighter
than usual.110

4. • Fig GI 71-2 Chronic hepatitis. (A) Longitudinal scan of the right lobe shows
marked coarsening of the liver echoes. Note the decrease in the
brightness and number of the portal vein radicle walls (arrow). (B) In
another patient, the liver pattern is even more coarsened. Note the
increased brightness of the band through the mid-portion of the liver,
corresponding to the maximum zone of sensitivity. The portal vein radicle
walls seen within this bright zone have no internal echoes (arrows).110
