Screening Mammograms


Regular mammograms are critical screening tools for early stage breast cancer. Sibley's dedicated breast imaging center and Sullivan Breast Center are part of Johns Hopkins Medicine, bringing exceptional care to the D.C. Region. 

State-of-the-Art Equipment 

Low dose 3-D tomosynthesis

3-D  mammography, provides the most accurate images to work from, which minimizes both the stress of false positives and reduces exposure to imaging radiation. It allows our dedicated breast radiologists to examine tissue one millimeter layer at a time. Fine details are more visible and image quality is more detailed.

Thin Slices


 Ultrasound can be used for evaluating palpable lesions, as well as supplemental screening. With breast ultrasound, the breast tissue is viewed using sonography instead of X-ray. This allows the radiologist to differentiate between a solid mass which could be benign or malignant and a liquid mass (such as a benign cyst).


 MRI uses a magnetic field, radio waves and computer software to produce detailed pictures of breast tissue.  It is used as a problem-solving tool following a questionable mammogram or ultrasound finding. Additionally, published American Cancer Society guidelines and a New England Journal of Medicine study support MRI screening as a supplement to mammography for women at high risk for developing breast cancer.


 The Sullivan Breast Center participates in research studies and clinical trials aimed at perfecting detection and improving outcomes.
