Module 11- Digital Breast Tomosynthesis
(DBT) UPDATED ACTUAL Questions and
CORRECT Answers
Which type of breast tissue makes the detection of small breast cancers difficult? - CORRECT
ANSWER - Dense fibroglandular
What percentage of women experience 5-year survival rates when cancer is detected early? -
CORRECT ANSWER - 99%
How are cancer and glandular tissue visualized on a mammogram? - CORRECT
ANSWER - c and d
How does DBT effect patient recall rates in women with dense breast tissue? - CORRECT
ANSWER - Decreases recall rates
How do women with fatty breasts compare to women with dense breasts regarding breast cancer
risk? - CORRECT ANSWER - Fatty breasts decrease risks
How is breast density measured? - CORRECT ANSWER - Visual assessment by
radiologist
How is breast tissue displayed in traditional 2D mammography? - CORRECT ANSWER -
Single, flat image, tissue overlap
What are the mammography screening guidelines of the American College of Radiology and
Society of Breast Imaging for women with average risk for developing breast cancer? -
CORRECT ANSWER - Annual mammo starting at 40
For which type of clinical use was DBT approved by the FDA? - CORRECT ANSWER -
Screening
, How does DBT influence the radiologist's interpretation skills? - CORRECT ANSWER -
Provides confidence
What is the movement of the x-ray during 3D imaging? - CORRECT ANSWER - Arc-like
What findings must be the optimal tomosynthesis system visualize? - CORRECT
ANSWER - Calcs, masses, arhcitectural distortion, and areas of asymmetries
What are the benefits of 3D mammography? (4) - CORRECT ANSWER - Improved
accuracy, better lesion characterization, lower screening recall rates, increased detection of early
cancer
Which clinical trial will compare 2D with 3D mamography? - CORRECT ANSWER -
TMIST
What is the meaning of the term "scan angle"? - CORRECT ANSWER - Total angular
range covered by xray tube
What are some advantages of a wider sweep angle? - CORRECT ANSWER - Better
separate objects that are close together
What is the name for the individual images that are obtained through the breast at different
angles? - CORRECT ANSWER - Projections
How are the tomosynthesis slices constructed? - CORRECT ANSWER - Computer
algorithms
How is slice thickness affected by the angular range? - CORRECT ANSWER - Wider
range= thinner slices
