| PURPOSE : To evaluate the contrast between hepatic vein and hepatic parenchyma with controlled velocities of ultrasound
in normal and fatty liver
MATERIALS and METHODS : 31 patients with normal liver and 39 patients with moderate degree of fatty liver were studies
with sonography with controlled velocities of ultrasound (1,580 m/sec, 1,540 m/sec, 1,500 m/sec,
1,460 m/sec). Sonographic images were captured with picture grabbing(Sono-PACS) and were recalled with visual
C++(Microsoft Redmond. WA, USA). The contrast between hepatic vein and parenchyma was measured
and analyzed on each sonographic image.
RESULTS : The number of patients with the highest contrast between hepatic vein and hepatic parenchyma among
the 31 patients with normal liver were 5(16.1%) with 1,580m/sec, 12(38.8%) with 1,540m/sec, 9(29.0%) with
1,500m/sec, and 5(16.1%) with 1,460m/sec. The number of patients with the highest contrast between hepatic
vein and hepatic parenchyma among the 39 patients with fatty liver were 3(7.7%) with 1,580m/sec, 7(17.9%)
with 1,540m/sec, 12(30.8%) with 1,500m/sec and 17(43.6%) with 1,460m/sec.
CONCLUSION : The velocity of ultrasound for the highest contrast between hepatic vein and hepatic parenchyma in
normal liver was 1,540 m/sec, and 1,460 m/sec in fatty liver. |
