1
Q

Omentum

A

Is a layer of fat that acts as insulation for your organs

2
Q

Do you normally see omentum on an ultrasound? Why or why not?

A
  1. No

2. Because if it is normal it is thin

3
Q

What are 2 posterior muscles close to the spine?

A
  1. Psoas

2. Quadratus lumborum

4
Q

What are 3 lateral muscles of the anterior border?

A
  1. External oblique
  2. Internal oblique
  3. Transverse abdomenous
5
Q

What is the medial muscle of the anterior border?

A

Rectus abdominus

6
Q

Where does the rectus abdominus run down?

A

Down the midline from the thorax to the pubis

7
Q

What is the most outer anterior muscle?

A

External oblique

8
Q

What is the middle anterior muscle?

A

Internal oblique

9
Q

What is the inner most anterior muscle?

A

Transverse abdominus

10
Q

Aponeuroses

A

Is a broad flat sheet of connective tissue

11
Q

What forms the rectus sheath?

A

The aponeuroses of the external/internal oblique and the transverse abdominus

12
Q

What does the rectus sheath cover?

A

Rectus abdominus fuse in the midline

13
Q

Linea albe

A

Tough band of connective tissue in the midline

- white line

14
Q

What is the echogenicity of the linea alba compared to muscles?

A

Hyperechogenic

- brighter

15
Q

What type of tissue is cura?

A

Connective

16
Q

What is the sonographic appearance of muscles?

A

Medium level of echogenicity

- may seem high echogenicity fibrous strands within

17
Q

What is the sonographic appearance of pure fat?

A

Anechoic

18
Q

What is the sonographic appearance of fat mixed with water?

A

Can be echogenic

19
Q

What is the sonographic shape of the diaphragm?

A

Curvilinear

- dome shaped

20
Q

What is the sonographic contour of the diaphragm?

A

Smooth

21
Q

What is the sonographic echogenicity of the diaphragm? (3)

A
  1. Muscles are a hypoechoic band
  2. Interface between liver (or spleen) is echogenic
    - thin
  3. Interface between diaphragm and lung is echogenic
    - thicker
22
Q

What anchors the diaphragm to the spine and joins the midline?

A

Crura

23
Q

How does the right crura show up on an ultrasound?

A

This hypoechoic band

- the left is not normally seen
