Q

Which is more superior, the hepatic arteries or the hepatic veins?

A

Hepatic veins

- hepatic arteries are more inferior

17
Q

What is the only fissure we see anatomically?

A

The main lobar fissure

18
Q

What happens to the hepatic veins are it moves toward the IVC?

A

They get larger

19
Q

Where do the hepatic veins course to?

20
Q

Where does the liver start and as you go to the left what happens to it?

A

The liver starts posterior and gets more anterior as you move left

21
Q

Intersegmental

A

There is a clear division between borders

22
Q

What is an example of intersegmental?

A

Hepatic veins

23
Q

Intrasegmental

A

Courses within

24
Q

25
Where do you measure when you measure the liver?
Posterior superior to anterior inferior tip
26
What is the range of measurement for the midclavicular line for the right lobe?
13cm-17cm
27
What is the range measurement for the left lobe?
Variable | - different on every person
28
How do we establish if the liver is too big in an ultrasound?
The surround relative organs
29
What is the echogenicity of the liver?
Moderately echogenic throughout - hypoechoic compared to the spleen - hyperechoic compared to the kidney
30
What is the echotexture of the liver?
Homogenous
31
What is the contour of the liver?

Triangular shape
33
What is the shape of the right lobe?
Variable
34
What are 2 scanning approaches for the liver?
1. Subcostal - under the ribs 2. Intercostal - between the ribs
35
What are 2 different positions the patient can be in to scan the liver?
