Mammography is more/less effective in women with denser breasts
Less
Give some advantages of mammography
Images whole of breast
High sensitivity for detecting DCIS
Reduces population mortality
Give some disadvantages of mammography

Uncomfortable
What is involved in tomosynthesis?
Multiple mammographic images are taken from different angles
What is involved in contrast enhanced spectral mammography?
An image of the breast is taken with/without IV contrast and a subtraction image is produced

MRI
Why is MRI rarely used to detect breast cancer?

Does not decrease positive margins/local recurrence
When is MRI used for imaging of the breast?
Lobular breast cancer (difficult to pick up on routine imaging)
