Screening Breast Ultrasound

In a screening breast ultrasound, a handheld device is used to send ultra-frequency sound waves into the breast.  These sound waves are reflected back differently from different types of normal tissue and cancers.  There are certain limitations of ultrasound in a screening application.

Characteristics of screening breast ultrasound:

  • Moderate sensitivity for breast cancer detection
  • Low specificity for breast cancer detection (As a screening modality, it has a 91% false positive rate.)
  • Unaffected by dense breast
  • No radiation dose
  • Recommended only for women who cannot undergo MRI

Breast MRI (Magnetic Resonance Imaging)

MRI uses a magnetic field and radio waves to create detailed images of the body. When performed using intravenous contrast, MRI can show the difference between enhancement of normal and abnormal breast tissue. This difference is not affected by the density of the breast tissue. MRI is therefore helpful in finding a subset of cancers that can be obscured by tissue on mammogram. Research studies have shown MRI to be very effective in finding breast cancers in dense breasts.

Characteristics of MRI

  • High sensitivity for breast cancer detection
  • Moderate specificity for breast cancer detection
  • Unaffected by dense breast
  • No radiation dose
  • Recommended for women with a high risk of developing breast cancer
