Diagnostic Mammography with Spot Compression Views or Digital Breast Tomosynthesis

Standard Diagnostic Workup Algorithm

The American College of Radiology recommends diagnostic mammography with additional views, including spot compression views, as the standard initial step in evaluating an abnormal screening mammogram 1
Spot compression views use a small compression paddle to apply focal compression to the specific area, helping to characterize whether an asymmetry or mass is real or artifactual 1
Magnification views are particularly helpful when evaluating associated microcalcifications, as recommended by the American College of Radiology 2, 1

The American College of Radiology recommends Digital Breast Tomosynthesis (DBT) as a modern alternative to traditional spot compression views, with equivalent or superior diagnostic accuracy 1

Targeted ultrasound of the area of concern should be performed concurrently with diagnostic mammography to identify potentially benign causes and provide a target for biopsy if indicated, as recommended by the American College of Radiology 1
Ultrasound helps distinguish between fluid and solid tissue, which mammography alone cannot reliably differentiate, according to the Journal of the American College of Radiology 3

The American College of Radiology advises against ordering "screening mammography" for an abnormal finding, as this requires diagnostic evaluation with additional views 1
The American College of Radiology recommends not relying on ultrasound alone without mammographic evaluation, as mammography detects microcalcifications and architectural distortion that ultrasound may miss 4

The American College of Radiology recommends clinical re-examination in 3-6 months with follow-up imaging every 6-12 months for 1-2 years to assess stability for BI-RADS 1-3 findings 1
The American College of Radiology advises proceeding directly to image-guided core needle biopsy for BI-RADS 4-5 findings 1
