Breast MRI

An MRI uses a magnetic field and radio waves to build very detailed images. It is a powerful tool reserved for specific situations — not a routine test.

MRI is extremely sensitive and is used when extra detail truly matters: in women at high genetic risk, to assess the extent of a known cancer, to check implants, or when the results of other tests disagree.

What to expect

  • You lie face down on a padded table inside the scanner
  • A contrast agent is injected into a vein for sharper images
  • The exam takes about 30–60 minutes
  • The machine is loud — headphones or music are provided

Because MRI is so sensitive, it sometimes shows areas that need checking but turn out harmless. Your team will interpret the MRI alongside mammography and ultrasound for the full picture.

In brief

Magnetic imaging, no radiation
Used for high-risk screening and detailed assessment
Sensitive — findings often need confirmation

What you can do

Follow your team’s advice

MRI is only prescribed when it genuinely adds information.

Mention implants or claustrophobia

Both can be anticipated.
