What is the minimum frequency used in breast ultrasound? - ANS10 MHz
Define axial resolution: - ANSThe ability to visualize 2 targets as separate that lie parallel to the
sound beam
Define lateral resolution: - ANSThe ability to visualize 2 targets as separate that lie
perpendicular to the sound beam
Define elevational resolution: - ANSThe ability to image structures in the Z axis
What are the 2 main mammography views? - ANSCraniocaudal and mediolateral
What "color" is radiolucent? - ANSGray
What "color" is radiopaque? - ANSWhite
Is fat radioloucent or radiopaque? - ANSRadiolucent
List 3 structures seen as radiopaque on mammo: - ANSWater, calcium, and fibrous tissue
The 2 major arterial supplies to the breast are: - ANSLateral thoracic artery and internal
mammary artery
The lateral thoracic artery arises from the: - ANSAxillary artery
The internal mammary artery arises from the: - ANSSubclavian artery
What are the 4 main veins that drain the breast? - ANSInternal mammary, axillary, subclavian
and intercostal veins
What is the functional unit of the breast? - ANSAcini
Which ducts transport milk from the acini to the nipple? - ANSLactfierous ducts
Acini give rise to: - ANSTDLU's
How many lobes are there per breast? - ANS15-20
What is the normal AP measurement of a lactiferous duct? - ANSLess than 3mm
