Digital Mammography Has Persistently Increased High-Grade and Overall DCIS Detection Without Altering Upgrade Rate.

The purpose of this article is to evaluate whether digital mammography (DM) is associated with persistent increased detection of ductal carcinoma in situ (DCIS) or has altered the upgrade rate of DCIS to invasive cancer. An institutional review board-approved retrospective search identified DCIS diagnosed in women with mammographic calcifications between 2001 and 2014. Ipsilateral cancer within 2 years, masses, papillary DCIS, and patients with outside imaging were excluded, yielding 484 cases.

Digital Breast Tomosynthesis Slab Thickness: Impact on Reader Performance and Interpretation Time.

Background Digital breast tomosynthesis (DBT) helps reduce recall rates and improve cancer detection compared with two-dimensional (2D) mammography but has a longer interpretation time. Purpose To evaluate the effect of DBT slab thickness and overlap on reader performance and interpretation time in the absence of 1-mm slices. Materials and Methods In this retrospective HIPAA-compliant multireader study of DBT examinations performed between August 2013 and July 2017, four fellowship-trained breast imaging radiologists blinded to final histologic findings interpreted DBT examinations by using a standard protocol (10-mm slabs with 5-mm overlap, 1-mm slices, synthetic 2D mammogram) and an experimental protocol (6-mm slabs with 3-mm overlap, synthetic 2D mammogram) with a crossover design.

The Breast Radiologist as a Public Educator: Designing an Effective Presentation for a Lay Audience.

Educating the public about breast cancer screening and diagnosis is important. Medical and regulatory agencies encourage shared decision making about undergoing breast cancer screening, and there are many places women can get information and misinformation. The Internet and other media sources present information that may not be correct or understandable.

Use of Screening Mammography to Detect Occult Malignancy in Autologous Breast Reconstructions: A 15-year Experience.

Purpose To examine how often screening mammography depicts clinically occult malignancy in breast reconstruction with autologous myocutaneous flaps (AMFs). Materials and Methods Between January 1, 2000, and July 15, 2015, the authors retrospectively identified 515 women who had undergone mammography of 618 AMFs and who had at least 1 year of clinical follow-up. Of the 618 AMFs, 485 (78.

Availability of prior mammograms affects incomplete report rates in mobile screening mammography.

Purpose: Mobile mammography can improve access to screening mammography in rural areas and underserved populations. We evaluated the frequency of incomplete reports in mobile mammography screening and the relationships between prior mammograms and recall rates.

Methods: The frequency of incomplete mammogram reports, the subgroups of those needing prior comparison mammograms, recalls for additional imaging, and availability of prior mammograms of a mobile screening mammography unit were compared with fixed site mammography from January 1, 2007 through December 31, 2009.

Harms of Restrictive Risk-Based Mammographic Breast Cancer Screening.

Objective: The objective of this study was to determine if restrictive risk-based mammographic screening could miss breast cancers that population-based screening could detect.

Materials And Methods: Through a retrospective search of records at a single institution, we identified 552 screen-detected breast cancers in 533 patients. All in situ and invasive breast cancers detected at screening between January 1, 2011, and December 31, 2014, were included.

Surgical biopsy is still necessary for BI-RADS 4 calcifications found on digital mammography that are technically too faint for stereotactic core biopsy.

The purpose of this study was to evaluate the outcome of faint BI-RADS 4 calcifications detected with digital mammography that were not amenable to stereotactic core biopsy due to suboptimal visualization. Following Institutional Review Board approval, a HIPAA compliant retrospective search identified 665 wire-localized surgical excisions of calcifications in 606 patients between 2007 and 2010. We included all patients that had surgical excision for initial diagnostic biopsy due to poor calcification visualization, whose current imaging was entirely digital and performed at our institution and who did not have a diagnosis of breast cancer within the prior 2 years.

Outcomes of solid palpable masses assessed as BI-RADS 3 or 4A: a retrospective review.

The purpose of this study was to evaluate the outcomes and cancer rate in solid palpable masses with benign features assessed as BI-RADS 3 or 4A. This study was Institutional Review Board approved. Mammography and breast ultrasound reports in our Radiology Information System were searched for solid, palpable masses with benign features described from 1/1/2000 to 12/31/2009, and retrospectively reviewed.

Does digital mammography increase detection of high-risk breast lesions presenting as calcifications?

Objective: The objective of our study was to evaluate whether the transition from film-screen mammography (FSM) to digital mammography (DM) was associated with increased detection of high-risk breast lesions.

Materials And Methods: A retrospective search identified 142 cases of atypia or lobular neoplasia (LN) diagnosed in women with mammographic calcifications between January 2004 and August 2010. We excluded lesions upgraded to cancer at excisional biopsy, lesions in women with ipsilateral cancer within 2 years of mammography, and lesions that presented as a mass only.

Adherence to screening mammography among American Indian women of the Northern Plains.

Breast cancer is a burden for American Indian (AI) women who have younger age at diagnosis and higher stage of disease. Rural areas also have had less access to screening mammography. An Indian Health Service Mobile Women's Health Unit (MWHU) was implemented to improve mammogram screening of AI women in the Northern Plains.

Breast mass characterization using 3-dimensional automated ultrasound as an adjunct to digital breast tomosynthesis: a pilot study.

Objectives: The purpose of this study was to retrospectively evaluate the effect of 3-dimensional automated ultrasound (3D-AUS) as an adjunct to digital breast tomosynthesis (DBT) on radiologists' performance and confidence in discriminating malignant and benign breast masses.

Methods: Two-view DBT (craniocaudal and mediolateral oblique or lateral) and single-view 3D-AUS images were acquired from 51 patients with subsequently biopsy-proven masses (13 malignant and 38 benign). Six experienced radiologists rated, on a 13-point scale, the likelihood of malignancy of an identified mass, first by reading the DBT images alone, followed immediately by reading the DBT images with automatically coregistered 3D-AUS images.

Ensuring excision of intraductal lesions: marker placement at time of ductography.

Rationale And Objectives: To propose grid coordinate marker placement for patients with suspicious ductogram findings occult on routine workup. To compare the success of marker placement and wire localization (WL) with ductogram-guided WL.

Materials And Methods: A retrospective search of radiology records identified all patients referred for ductography between January 2001 and May 2008.

Breast fibroadenomas in the pediatric population: common and uncommon sonographic findings.

Background: Sonography is usually requested to evaluate palpable pediatric breast lumps, and solid masses are almost always fibroadenomas. Lack of familiarity with the findings of fibroadenomas can lead to diagnostic uncertainty and sometimes unnecessary biopsy and excision. We sought to review the spectrum of sonographic findings in our cases of pathology proven pediatric fibroadenomas.

Sonographically-guided metallic marker placement at time of wire localization for intraductal or cystic lesions: a method to verify lesion retrieval.

Rationale And Objectives: To propose deploying a metallic marker using sonographic guidance immediately before wire localization for excisional biopsy to identify intraductal or complex cystic lesions at specimen radiography.

Materials And Methods: Institutional review board approval was obtained for this study and is Health Insurance Portability and Accountability Act compliant. The clinical, radiographic, and pathologic records of 21 patients, ages 21-78 years, with 22 intraductal or complex cystic masses who underwent excisional biopsy with wire localization immediately after sonographically-guided marker placement were reviewed.

Costs of achieving high patient compliance after recall from screening mammography.

Objective: The purpose of our study was to document the hidden costs in achieving high recall patient compliance from an off-site screening mammography program.

Materials And Methods: This study was approved by our institutional review board. At our institution, no patient was placed in final BI-RADS assessment category 3, 4, or 5 without a diagnostic study.
