Mammo Flashcards
Mammographic Position?
Anatomical Position
Goals for Mammography Positioning
true anatomical position(with nipple perpendicular to the chest wall) to maximize visualization of the breast tissue and to avoid overlapping of structures
When positioning for mammography we need to bring back breast to?

Grade 1
Mild Sagging
Grade 2
Moderate Sagging
Grade 3
Significant sagging
Pseudoptosis
Lower Breast Sagging
Parenchymal maldistribution
Unusual Shape

INFRAMMARY FOLD another name?
inframammary crease or inframammary line
the natural lower boundary of the breast, the place where the breast and the chest meet.
Inframammary Fold
Folds in IMF?
Horizontal Fold
Vertical Fold
Horizontal Fold found in area of breast?

Importance of Mammo Positioning
Nipple is in profile
Why nipple in profile is important?
avoid mistaking the nipple for a mass.

MEDIOLATERAL OBLIQUE(MLO) angled cassette?
angled 45 ° (depends on the body habitus)
Steeper angle
