unit 7 Flashcards
when doing a female pelvis, where does the horizontal alignment light go?
on the ASIS
sagittal images of the pelvis demonstrate
organs that lie in the midline (bladder, rectum, prostate, uterus)
axial images of the pelvis demonstrate
organs that lie laterally (ovaries, lymph nodes)
on a female pelvis angle the axial slices
perpendicular to the uterus
on the coronal images angle the slices
parallel to the uterus
*if pt has had a hysterectomy there should be no angle on slices
vendor options to help reduce metal artifact
MARS
Mavric
SEMAC
a malignant bone tumor that affects children and young adults usually develops during puberty
ewing’s sarcoma
to reduce metal artifact use a _____ instead of fat suppression techniques
STIR
to reduce metal artifact use _____ instead of gradient echo
TSE/FSE
to reduce metal artifact some things you can adjust are
- add NEX/NSA
- increase echo train length
- wider/more bandwidth
- use thin slices
coverage on sagittals for a female pelvis includes
the left femoral head to right femoral head & ASIS to obturator foramen
what could be a male pelvis indication
elevated PSA levels in blood work
where does the horizontal alignment light pass through on a male pelvis?
midway between the pubis symphysis & the iliac crests
artifact considerations for pelvis exams
bowel motion & respiratory motion
how are the sagittal slices set up for a male pelvis
parallel with the prostate & superior to the seminal vesicles
