1

Primary modality in imaging pelvic organs

Ultrasound

2

Used to diagnose congenital abnormalities and mechanical causes of infertility

HSG

3

Transducer type with greater spatial resolution but limited penetration

High frequency

4

High frequency transducers are used for

endoluminal applications

5

Endocavitary transducers are used for:

transabdominal and transvaginal ultrasound

6

Transducer used for small parts and children

linear transducer

7

Transducer type with greater spatial penetration but poor resolution

Low frequency

8

Transducer used for abdominal, pelvic, obstetric ultrasound

convex transducer

9

Swinging the transducer left to right produces:

sagittal image

10

Swinging the transducer up and down produces

transverse image

11

shape of prepubertal infantile uterus

cigar-shaped

12

shape of postpubertal uterus

pear-shaped

13

difference of anteverted/retroverted from anteflexed/retroflexed

-verted - pointing in anterior (ante) or posterior (retro) directions

-flexed - folded anteriorly (ante) or posteriorly (retro)

14

for imaging the uterus, how is the ultrasound done so that it is clearer

transvaginal approach

15

an ovarian physiologic cyst resolves in

10 weeks

16

how to differentiate an endometrioma from a hemorrhagic cyst in the ovary

endometrioma - does not resolve in 2 weeks
hemorrhagic cyst - resolves in 2 weeks

17

adnexa are composed of:

Ovaries
Fallopian tube
Broad ligament
Ovarian and uterine vessels

18

dense fibrous tissue covering the testis

tunica albuginea

19

invagination of tunica albuginea produces

mediastinal testes

20

Transverse view of both testes

Dolly Parton view

21

When the uterus is in the secretory stage, it is uniformly _________

Echogenic (light gray to white)

22

Trilaminar endometrium seen in pelvic imaging is indicative of what phase of the menstrual cycle?

Proliferative phase

23

These kinds of follicles are seen in postmenoposal ovary

No follicles are seen in postmenoposal ovaries

24

Focal lesions in the ovary; cysts with thick walls and variable internal echoes due to hemorrhage

Endometrioma

25

Condition resulting from minimal fluid in sac, manifesting as anechoic fluid surrounding the testicle

Hydrocoele

26

Condition resulting in increased vascularity of epididymis and testes, producing hyperechoic ultrasound images

Acute epididymo-orchitis

27

Acute epididymo-orchitis is (hypoechoic/hyperechoic) while hydrocoele is (hypoechoic/hyperechoic)

Acute epididymo-orchitis – hyperechoic

Hydrocoele – hypoechoic

28

View best used to compare testes and detect focal abnormalities

Dolly Parton View (transverse view of both testes)

29

A patient with benign prostatic hypertrophy will manifest the following findings on a transabdominal ultrasound of prostate and bladder, EXCEPT

a. enlarged central portion of prostate
b. enlarged peripheral portion of prostate
c. increased heterogeneity of prostatic image

B

30

A convoluted, hypoechoic structure at the base of the prostate and urinary bladder

Seminal vesicle
