The initial localizing scout image is obtained using DBT, which can then also be used to calculate the target location coordinates. Certain mammographic abnormalities that have limited visualization on conventional FFDM, including noncalcified masses, faint microcalcifications and some architectural distortions, can make S-VAB difficult.

In addition, the prone table system is an expensive, and perhaps less cost-effective, unit that only has the ability to perform stereotactic biopsies and cannot be used for routine mammographic imaging.
One of the largest advantages of the upright over the prone table is that there is no weight limit.
This limitation is typically circumvented by placing both the ipsilateral arm and the breast of interest through the table opening (arm through the hole technique) in order to access more posterior tissue.
Patient factors such as mobility and weight also may limit use of the prone stereotactic table.
A known disadvantage to the upright VAB is an increased possibility of patient experiencing a vasovagal reaction when compared to the prone position and increased patient anxiety due to the ability to see the needle, skin entry site, and tissue sampling during the procedure.
Additionally, there is no requirement for triangulation of the mammographic abnormality via stereo pair images as the depth is calculated by the system automatically when localizing an abnormality on scout tomosynthesis images (Figures 5-6).Recent studies have demonstrated that screening mammography utilizing DBT with FFDM has resulted in decreased recall rates and increased invasive cancer detection compared to conventional digital screening mammography.As patients become more aware of these studies, more of them are requesting DBT with their screening mammograms.Some of the chairs used during the upright biopsy are reclinable, which has the added benefit to allow for easier access of more posterior and lateral tissue while putting the patient in a supine oblique position.Additionally, the upright VAB unit is an add-on device to an existing upright mammographic machine; thus, it is an overall cheaper system to implement.Huynh is a Radiologist in Breast Imaging, Department of Radiology, at Baylor St. The authors have no conflicts of interest to declare.In breast imaging practice we seek to provide care that is compas-sionate, patient-centered and evidence-based. healthcare, the economic environment for breast imaging is complex and evolving.Effective May 1, 2018, North Carolina Medicaid will cover digital breast tomosynthesis (3D tomosynthesis) for both screening and diagnostic mammography.Providers must submit claims with Healthcare Common Procedure Coding System (HCPCS) code G0279 (Diagnostic digital breast tomosynthesis, unilateral or bilateral) in addition to screening or diagnostic mammography Common Procedural Terminology (CPT) codes 77065-77067.As early studies are demonstrating the advantages of DBT over FFDM, including increased invasive cancer detection rates particularly with abnormalities identified only on DBT, DBT-VAB is being used more frequently.DBT-VAB has shown many advantages and few disadvantages when compared to S-VAB and may eventually replace S-VAB in terms of sampling mammographic abnormalities identified on both DBT and FFDM.
