Mammographic Positioning

Question 1

ML Mediolateral

Answer 1

Cr 90 deg medial -> lateral. Used to visualize milk of calcium. Reduce superimposition of tissue. The detector will be at 3rd posterior area of axilla. Best demonstrates lateral lesions. Most common diagnostic vw

Question 2

LM lateromedial

Answer 2

Cr 90 deg lateral-> medial. Used to visualize milk of calcium. Detector at sternal notch. Best at visualizing medial lesions. Most common diagnostic vw

Question 3

XCCL exagg. Cc lat

Answer 3

Cr: sup->inf, 0 -
5 deg mod.
Demonstrates: anatomy that extends to outer aspect of breast. For pts with prominent tail of spence or a lot of glandular extensions. 10% of pts need this.
Criteria: shoulders stay level. Can angle laterally 0-5 deg. Nipple points medially.

Question 4

XCCM exagg. Cc Medial

Answer 4

CR: sup->inf, 0 deg.
Demonstrates: extreme posterior/medial anatomy.
Criteria: Nipple points laterally.

Question 5

Cleavage vw CV

Answer 5

CR: sup->inf 0 deg.
Demonstrtaes: anatomy in deep posterior & medial breast.
Criteria: No overlapping of breast.

Question 6

Axillary tail AT

Answer 6

CR: med->lat.
Demonstrates: entire axillary tail, most of lat breast. Shows clip in deep axilla. Used for axillary lumps/asymmetry.
Angle used should place AT parallel to IR

Question 7

CC rolled medial/lat
Ex: CCRM CCRL

Answer 7

CR: sup->inf. Breast will be rolled medially/laterally.
Demonstrates: determine location of lesion in CC. Used to see if lesion if in superior or inferior tissue.

Question 8

MLO rolled superior/inferior Ex: RT MLORS/MLORI

Answer 8

CR: med->lat breast will be rolled superiorly/inferorly
Demonstrates: confirms lesion found in MLO. Used to see if lesion is found on med/lat tissue.

Question 9

Anterior Compression AC

Answer 9

Used: unable to get anterior portion of breast taut. Will get anterior portion of breast completely compressed, nipple in profile, IMF open.

Question 10

Nipple in profile NP

Answer 10

ACR states: At least one vw on each side must get nipple in profile.

Question 11

Spot compression
Ex:RT spot cc

Answer 11

Reduces thickness & OID. Increases definition to better see asymmetry, architectural ual distortion & density. Use smaller paddles to increase effectiveness of compression.

Question 12

Tangential TAN

Answer 12

1. Palpable lump
2. Skin calc
   Palpable lump:
   Place BB over skin. Rotate IR so its parallel to line from BB to nipple. Rotate breast until BB is tangent to beam. Use a small/med paddle, center anteriorly. Places lump over fat.
   Skin calc:
   Verify if calcs are in skin. Uses spot mag. Rotate ISRD parallel to line from BB to nipple. Rotate until breast is tangent to beam.

Question 13

Displacement Views
Ex: Eklund views

Answer 13

Requires displacement of implant to chest wall. Implant displaced posteriorly & superiorly. Breast tissue gently pulled forward & compressed. detector raised to help hold implant back
