female reproduction imaging techniques Flashcards
1
Q
advantages of Ultrasound
A
- no radiation
- non-invasive
- cheap
- localisation of lumps
- well-tolerated
- easily available
- can take measurements
2
Q
disadvantages of ultrasound
A
- this modality is operator dependent- because it is so specialised
- does not give functional information
- cannot image gas or air-filled structures
- bones also get in the way
- patient habitus - bigger patients may affect resolution/quality of image
- requires prep
3
Q
ultrasound female pelvis
A
- first choice modality
- followed up by other imaging modalities (depending on findings)
4
Q
reasons to ultrasound
A
- unusual pain or bleeding
- infertility
- menstrual problems
- confirmation of a pelvis mass
5
Q
why is it important to know where the patient is in their cycle
A
- normal appearances may be reported as abnormal
- Abnormal appearances may be reported as normal
6
Q
endometrium changes through cycle (day 1-4)
A
- menstruation
- may see fluid in the cavity when imaging
7
Q
endometrium changes through cycle (days 5-8)
A
- early proliferative phase
- very thin echogenic line
8
Q
endometrium changes through cycle (days 9-15)
A
- follicular phase
- becomes thicker
- 3 line sign
- ovulation occurs
9
Q
endometrium changes through cycle (days 16-28)
A
- luteal phase
- when endometrium is the thickest
10
Q
Transabdominal approach
A
- normal eating and drinking
- patient is not required to change
- must have a full bladder
11
Q
why is a full bladder needed
A
- moves bowel out of the way
- useful as an anatomical landmark
- manipulates the position of the uterus for it to be visualised
12
Q
transabdominal scan - technique
A
- patient ID
- consent
- patient is supine
- paper towels to protect clothes
- questioning the patient about their cycle
- longitudinal and transverse sections
13
Q
TA aftercare
A
- patient is given tissue to clean off gel
- they can go to the toilet
- discuss results
14
Q
TA advantages
A
- large FOV
- visualise relationship with other organs
- can image large masses
- can image other areas
- can take measurements
15
Q
TA disadvantages
A
- limited resolution
- cant pick up small lesions
- uncomfortable full bladder
- some bladders take longer to fill
- retroverted uterus - difficult to scan
