Abstract
- PURPOSE
To evaluate the contrast between hepatic vein and hepatic parenchyma with controlled velocities of ultra-sound in normal and fatty liver.
MATERIALS AND METHODS
31 patients with normal liver and 39 patients with moderate degree of fatty liver were s-tudies 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 vi-sual 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.
