NORMAL- LIVER SCAN
- The normal liver parenchyma appears homogeneous.
- Interrupted by the portal vein and its branches which are seen as linear tubular structures with reflective walls.
- The thinner hepatic veins are non- reflective.
- It should be possible to follow the hepatic veins to their confluence with the inferior vena cava. Hepatic veins can be made to dilate when the patient performs the Valsalva manoeuvre
