Breast Screening with DWI

Details and patient eligibility

About

A prospective observational multicenter study to compare the outcome of breast cancer surveillance using mammography, breast US, contrast-enhanced MRI, and diffusion-weighted MR imaging (DWI) as a screening tool, in the high-risk women for breast cancer.

• Primary objective: To compare the sensitivity of mammography, breast US, contrast-enhanced MRI, and DWI for the detection of breast cancer

• Secondary objective:

  1. To compare the specificity of mammography, breast US, contrast-enhanced MRI, and DWI for the detection of breast cancer
  2. To compare the cancer detection rate of mammography, breast US, contrast-enhanced MRI, and DWI
  3. To compare the characteristics of detected cancers

Full description

• Mammography, breast US, contrast-enhanced MRI, and DWI will be performed on the same day or within 1 month at baseline and then after 1 year, and images will be interpreted independently according to the Breast Imaging Reporting and Data System (BI-RADS) by experienced radiologists.
• Each eligible woman, who provides informed consent for this study, will undergo mammography, breast US, contrast-enhanced MRI, and DWI at a 3T MR scanner.
• Contrast-enhanced breast MRI will be performed before and after a gadolinium-based contrast agent injection.
• Before contrast injection, DWI with b-value of 0, 800 and 1200 s/mm2 will be performed and will transfer into the server.
• A total of 890 high-risk women for breast cancer will be enrolled in this study.
• The BI-RADS 3 or higher is defined as test-positive. The reference standard will be a biopsy or at least 1 year of follow-up.

Enrollment: 890 estimated patients

Sex: Female

Ages: 30 to 75 years old

Volunteers: Accepts Healthy Volunteers
