Anatomy🫀
What layer of the breast contains the coopers ligaments?
the subcutaneous (premammary) layer!
this is a benign tumor common in young women that is oval and homogeneous
A fibroadenoma
What is the most common reason for a breast ultrasound
a palpable lump
what shape suggests a benign mass
oval shaped
What is the standard patient position
supine with the arm raised
name the three main layers that you can see on ultrasound
1. Skin/premammary layer
2. Mammary layer
3. Retromammary layer
This is a cyst with internal echoes and debris level
a complicated cyst
what is a mammography finding that requires ultrasound
asymmetry
taller than wide
what is the typical transducer frequency
7-12MHZ
What is the termination point of the TDLU
The acinus
This is the most common malignant breast cancer, it appears irregular, taller-than-wide, hypoechoic, spiculated, and shows posterior shadowing.
invasive ductal carcinoma
Age where ultrasound is proffered over mammography
30
What is the typical echogenicity of breast cancer
hypoechoic
What is the scan plane that uses the nipple as the center point
radial/antiradial
What is the area where most breast cancers originate?
The TDLU
Mastitis
What is the pattern seen when ligaments are pulled by a mass
architectural distortion
What can you do to differentiate cystic vs solid masses
use compression
What is the muscle posterior to the retromammary layer?
This is a cancer that grows between lobules and doesn’t form a mass
Invasive lobular carcinoma
What is a key assessment for breast implants
checking for rupture
what is the BI-RADS category for highly suspicious masses
BI-RADS 5
This technique reduces speckle and improves margin clarity when assessing a mass
spatial compounding
