pregnancy imaging and foetal development Flashcards
1
Q
3 key areas for foetal development
A
3 trimesters - each about 3 months each
2
Q
placenta
A
- an organ attached to the womb during pregnancy
- provides oxygen and nutrients to start the baby growing
- removes waster from baby’s blood
3
Q
common placental problems
A
placenta previa
placental abruption
placenta accreta
4
Q
placental abruption
A
- where the placenta moves away from the wall of the uterus
- can cause a bleed
- may feel pain stomach
5
Q
placenta previa
A
the placenta partially or fully covers the opening of the cervix
- smoking increases risk
6
Q
placenta accreta
A
- is when the placenta does not attach to the lining of the uterus
7
Q
3 stages of placenta accreta
A
placenta percreta, placenta increta and placenta accreta
8
Q
imaging during pregnancy
A
- ultrasound
- MRI
- CT
- X-ray
9
Q
CT and X-ray is used for ‘pelvimetry’
A
assessing the size of the baby’s head, in relation to the mother’s pelvis
10
Q
risk factors in pelvimetry
A
- small mother
- if baby is breeched
- genetic condition
- gestational diabetes
11
Q
measurements for pelvimetry
A
pelvic diameter
- between the ischial spines
- between the obstetric conjugate to sym. pubis
- sacrial-coccygeal joint to the bottom of the sym. pubis
12
Q
mri
A
used to look into greater detail at abnormalities
13
Q
disadvantages of mri during pregnancy
A
- patient may not fit in machine
- have to avoid 1st trimester
- foetal heating
14
Q
advantages of ultrasound
A
- no radiation
- easily available
- dynamic - see movement
- measurements
15
Q
disadvantages of ultrasound
A
- requires prep
- patient habitus
- cant image gas
