Sonographic Terminology

6. Remnant of the left umbilical vein, seen in the transverse plane as a triangular echogenic foci dividing the medial and lateral segments of the left lobe of the liver.
8. Accumulation of serous fluid in the peritoneal cavity.
10. Blood flow toward the liver.
11. Fibrous tissue network that is richly supplied by blood vessels and nerves located between the skin and the underlying structures.
14. Caused by treatment; either intentional or unintentional.
15. Describes a region or portion on the sonogram that appears echo-free.
16. Remnant of ductus venosus seen as echogenic line separating caudate lobe from the left lobe.
20. Describes structures of equal echo density.
22. Describes tissues or organ structures on the sonogram having several different echo characteristics.
26. Describes an organ or tissue capable of producing echoes by reflecting the acoustic beam.
27. Describes image echoes brighter than surrounding tissues or those brighter than what is normal for that tissue or organ.
29. Connection between two vessels.
30. Rhythmic contraction of the GI tract that propels food through it
31. Fold in the parietal peritoneum that extends from the umbilicus to the diaphragm and contains the ligamentum teres.

1. Blood flow away from the liver.
2. Fibroelastic connective tissue layer that surrounds the liver.
3. Describes structures of equal echo density.
4. Organs posterior to the parietal peritoneum, which are typically covered on their anterior surface or fatty capsule by parietal peritoneum.
5. Focal dilatation of an artery caused by a structural weakness in the wall.
7. Fluid accumulation in the pleural cavity.
9. Divides the right and left lobes of the liver; seen in sagittal plane as an echogenic line between the neck of the gallbladder and the main portal vein.
12. Area of an organ where blood vessels, lymph, and nerves enter and exit.
13. Enlarged liver.
17. Solid organs within the peritoneal cavity that are covered by visceral peritoneum.
18. Peritoneum lining the walls of the peritoneal cavity.
19. Describes regions or portions on the sonogram where the echoes are not as bright as surrounding tissues or are less bright than normal.
21. Fissure where the portal vein and hepatic artery enter the liver and the common hepatic duct exits.
23. Yellowish pigmentation of the skin and whites of the eyes caused by increased levels of bilirubin in the blood.
24. Dilatation, expansion, or distention.
25. Peritoneum encasing peritoneal organs.
28. Two layers of fused peritoneum that conduct nerves, lymph, and blood vessels between the small bowel/colon and the posterior peritoneal cavity wall.
