1

What is the most common imaging used in gynaecology?

USS

2

What presenting complaints in women would indicate pelvic imaging?

Pelvic pain

Pelvic mass

Dodgy bleeding (intermenstrual, post-menopause)

Infertility

3

Which gland is commonly involved in male/female infertility?

How is it imaged?

Pituitary gland

MRI pituitary

4

What are two ultrasound views used for pelvic imaging?

Transabdominal

Transvaginal

5

Transabdominal ultrasound is (invasive / non-invasive).

non-invasive

6

Transvaginal ultrasound is (invasive / non-invasive).

invasive

It's inserted

7

Gas appears as which colour on ultrasound?

Black

8

Gas appears black on ultrasound. This presents a problem in transabdominal ultrasound scanning.

How is this solved?

Full bladder

Shifts gas-filled bowel out of the way and acts as a reference point

9

In transvaginal ultrasound, where a probe is inserted into the vagina, the patient's bladder needs to be (empty/full).

empty

10

Can transvaginal ultrasound be used in patients who haven't been sexually active?

No

11

What colour does the endometrium appear on ultrasound?

White

12

What colour is free fluid on ultrasound?

Black

13

What imaging is used second-line in more complicated cases or to stage malignancies?

CT scan

14

What are the advantages of CT scanning over X-ray?

Multiple views, can scroll to select different slices

Higher resolution image

Can pick out more structures

15

CT scanning delivers a high dose of ___.

radiation

especially to testes/ovaries

16

Does MRI give the patient a dose of radiation?

No

But there are different risks (metal)

17

What are the two different MRI scans which patients can have?

T1

T2

relearn the difference

18

Which scan is used to stage cervical cancer?

Why?

MRI scan

CT not detailed enough

19

What colour does the endometrium appear on MRI?

White

20

What scan offers the most detailed image of the pelvis?

MRI scan

21

What scan is used to diagnose endometriosis?

MRI scan

As with normal endometrium, abnormal (& bleeding) tissue appears white

22

Which serial X-ray technique can be used to assess a woman's tubal patency?

Hysterosalpingography (HSG)

Like an angiogram for the uterine tubes

23

Which is injected into the cervix before HSG is carried out?

Contrast

24

What is seen lateral to the uterus and uterine tubes once contrast has been injected in HSG?

Peritoneal spill

If uterine tubes are patent, contrast will pass through them and pass into peritoneal cavity at the distal end

25

Where does ovarian cancer tend to spread?

Why?

Peritoneal cavity

Space between ovaries and start of uterine tubes - continuous with " "

26

Where in the body does ovarian cancer tend to spread?

Peritoneal cavity

Liver SURFACE (not intrahepatic)

27

What can be used to differentiate bowel from solid deposits on a CT or MRI scan?

Contrast

28

Which specific type of scan is used to identify cervical cancer?

MRI scan

T2-weighted
