Imaging in gynae* Flashcards
what are the two types of USS that are done
trans abdominal
transvaginal
which type of USS needs to have a full bladder and why
which needs an empty bladder and why
transabdominal - full - bladder acts as an acoustic window - displaces the gas filled bowel loops out of the pelvis
transvaginal - require empty bladder as a full bladder can
make the examination
uncomfortable
which of the two types of USS is more invasive
transvaginal
which of the two USS is not suitable for individuals who have not been sexually active
transvaginal
when is CT used
as a second line ix after USS for people presenting with acute abdominal pain
to asses post surgical cx
staging of gynae malignancy
assessing response to treatments in patients after chemo/radio
who is MRI great for
children and women of reproductive age as there is no ionising radiation
when is MRI used in gynae patients
cancer staging - esp cervical cancer
further evaluation and characterisation of adnexal and uterine masses where USS/CT hasnt given a dx
MRI of pit gland in suspected prolactinoma
what can be used to diagnose endometriosis
laparoscopy
sometimes MRI
what is used to dx dermoid cysts
MR or CT
what is a HSG used for
how long does it take
how is it done
assessment of tubal potency in patients with infertility
can also assess outline of uterine activity
in 3-5 minutes
cervix is cannulated and radiopaque contrast instilled to fill the uterine cavity
ovarian cancer ix
US
then CT for staging
how does ovarian cancer disseminate
peritoneal spread
ix of cervical cancer
MR is better at CT for local disease
but CT is used to determine whether there are distant metastases
endometrial cancer ix
transvaginal US best for establishing abnormally thickened endometrium in post menopausal women with PMB
MR for degree of myometrial invasion
CT to look for distal nodal metastases and pulmonary mets
