Mammography UPDATED ACTUAL Exam
Questions and CORRECT Answers
What is Mammography - CORRECT ANSWER - X-ray imaging modality for detecting
breast pathology- example of soft tissue radiography
Location of cancer incidence within the breast - CORRECT ANSWER - 50 % in UOQ
breast cancer affects - CORRECT ANSWER - Affects one in nine women in her lifetime.
how many women are expected to die from breast CA - CORRECT ANSWER - One in 28
what is the benefit of Regular screening mammograms - CORRECT ANSWER - can find
breast cancer in the early stages, usually before it has spread.
Risk factors for Breast Cancer - CORRECT ANSWER - Risk doubles between age 45 and
65
Earlier onset ( <12) and later cessation (>52) of menstrual cycle
Prolonged use of Hormone Replacement Therapy or estrogen exposure
No children, or later age at birth of first child
what does Efficacy of screening mammography program relies on - CORRECT
ANSWER - low risk of imaging to high benefit of early cancer detection.
what is the risk of cancer caused for cancers detected due to mammography - CORRECT
ANSWER - 1 for every 1000
what kind of mammo will asymptomatic women have - CORRECT ANSWER - screening
,2 views done in screening - CORRECT ANSWER - Craniocaudad and mediolateral
oblique- CC & MLO
women with increased risk factors or symptoms (previous cancer diagnosis, breast implants )
have - CORRECT ANSWER - diagnostic mammo
why does Anatomy of the breast makes it difficult to image - CORRECT ANSWER -
Breast structures all have very similar density
what type of tissues make up a breast - CORRECT ANSWER - Fibrous, Glandular,
Adipose
where do where 80% of breast cancers form - CORRECT ANSWER - Glandular tissue
which breast tissue is MOST sensitive to radiation - CORRECT ANSWER - Glandular
on a mammogram , Adipose tissue appears - CORRECT ANSWER - dark
Glandular and fibrous tissue - CORRECT ANSWER - appears bright
Pre-menopausal women: Higher exposure needed - CORRECT ANSWER - Fibrous +
glandular tissue = more dense breasts
Post-menopausal women-Lower exposure used - CORRECT ANSWER - •More adipose
tissue = less dense breasts
why does Imaging of all other regions of the body produces images with adequate image contrast
- CORRECT ANSWER - In most regions of the body there is HIGH SUBJECT
CONTRAST
, why is Using HIGH kVp good for chest imaging - CORRECT ANSWER - decrease image
contrast (more scatter produced; less differential absorption)- Allows to see detail of bronchi,
mediastinum
Soft tissue imaging deals with body areas - CORRECT ANSWER - having LOW
SUBJECT CONTRAST
how is Mammography equipment is designed - CORRECT ANSWER - to maximize the
slight differences between fibrous, glandular and adipose soft tissues- yield an image with the
highest contrast possible= most diagnostic
why is Low kVp is used in mammography - CORRECT ANSWER - to MAXIMIZE
occurrence of photoelectric effect while MINIMIZING occurrence of Compton scatter radiation.
Photoelectric effect - CORRECT ANSWER - Inner shell electron ejected -X-ray is
absorbed
WHAT HAPPENS When x-ray is absorbed in PE absorption - CORRECT ANSWER - it
contributes to differential absorption
why do we want differential absorption - CORRECT ANSWER - gives our image contrast
differential absorption happens - CORRECT ANSWER - less often in low density
structures
more often when the beam has low energy (low kVp)
Compton Scatter - CORRECT ANSWER - Outer shell electron ejected & x-ray exits in a
different path with less
Compton Scatter is also called - CORRECT ANSWER - scatter radiation
