  2. Grading: BI-RADS (Breast Imaging Reporting and Data System) for Mammograms and Breast Ultrasound
    1. Category 0: Incomplete Imaging (additional imaging recommended)
    2. Category 1: Negative findings (no Breast lesions identified)
    3. Category 2: Benign findings
    4. Category 3: Indeterminate, probably benign findings (<2% cancer risk)
    5. Category 4: Suspicious for malignancy
    6. Category 5: Highly suggestive of malignancy
    7. Category 6: Biopsy proven malignancy
  3. Interpretation: Benign Mammogram Findings
    1. Intramammary Lymph Node
      1. Smooth walled mass within the Breast tissue
      2. Lucent center
      3. Usually Mammogram repeated in 6 months
    2. Smooth walled mass
      1. Associated with cyst or fibroadenoma
      2. Evaluate with breast Ultrasound
    3. Scattered Microcalcifications
      1. Bilateral shot-gun like appearance

Breast Imaging Reporting and Data System (C1511314)

Definition (NCI_NCI-GLOSS) A method used by radiologists to interpret and report in a standardized manner the results of mammography, ultrasound, and MRI used in breast cancer screening and diagnosis.
Definition (NCI) The Breast Imaging Reporting and Data System (BI-RADS) Atlas is a quality assurance guide to standardize breast-imaging reporting and to facilitate outcome monitoring. The atlas contains a guide to standardized mammographic reporting, including a breast-imaging lexicon of terminology, a report organization and assessment structure and coding system.
