A

Length x width x height (AP) x 0.523

2
Q

What is the mean ovarian volume in the first year?

A

1cc

3
Q

What is the mean ovarian volume in the 2nd year?

A

0.7cc

4
Q

What does the size of the ovary depend on?

A

Age

5
Q

What years does the ovarian volume considered stable?

A

1-5 years

6
Q

What years does the ovarian volume gradually increase?

A

5-menarche

- 4cc

7

6.8cc

8

18cc

9
Q

What is the mean ovarian volume post menopause?

A

1.2-5.8cc

10
Q

What volume is considered abnormal in post menopause for volume?

A

Over 8cc

11
Q

What is the echotecture for the ovary?

A

Relatively homogenous

12
Q

What is the echogenicity for the ovary? (3)

A
  1. Central, more echogenic medulla
  2. Small, well defined anechoic or cystic follicles may be seen in periphery in the cortex
  3. Echogenic ovarian foci
13
Q

What is commonly seen in the ovaries?

A

Echogenic ovarian foci

  • non shadowing
  • usually in the periphery
14
Q

What could focal calcification be?

A

Stromal reaction previous hemorrhage or infection

- should follow up if seen in early neoplasm

15
Q

What are follicles stimulated by in early proliferative phase?

A

Follicle stimulating hormone

- FSH

16
Q

When does the ovary increase in size until during the early proliferative phase?

A

Increase in size until day 8 or 9

17
Q

What happens to the follicles during the early proliferative phase?

A

One becomes dominant

18
Q

What size does the dominant follicle reach at ovulation?

A

2-2.5cm

19
Q

What develops if fluid in one of the nondominant follicles is not resorbed?

A

Follicular cyst

20
Q

Is the follicular cyst vascular?

A

No

21
Q

What develops after ovulation?

A

Corpus Luteum

22
Q

How is the corpus luteum seen in an ultrasound?

A

Seen as a small, hypoechoic or isoechoic structure in periphery of ovary
- empty house

23
Q

What does the corpus luteum do before menstration?

A

It involutes

- curls up?

24
Q

Why are you less likely to see the ovaries after a hysterectomy?

A

Due to loss of normal anatomic landmarks

25
Q

What does an ovary look like post menopausal sonographically? (2)

A
  1. Small
  2. Lack of follicles or completely absent
    - hard to find on Ultrasound
26
Q

ADNEXA

A

Appendages or accessory structures of an organ

27
Q

What does the ADNEXA refer to in the uterus? (3)

A
  1. The uterine tubes
  2. Ligaments
  3. Ovaries
