ABSTRACT
Background The use of digital breast tomosynthesis (DBT) is increasing over digital mammography (DM) following studies demonstrating lower recall rates (RRs) and higher cancer detection rates (CDRs). However, inconsistent interpretation of evidence on the risks and benefits of mammography has resulted in varying screening mammography recommendations. Purpose To evaluate screening outcomes among women in the United States who underwent routine DM or DBT mammographic screening. Materials and Methods This retrospective cohort study included women aged 40-79 years who underwent DM or DBT screening mammograms between January 2014 and December 2020. Outcomes of RR, CDR, positive predictive value of recall (PPV1), biopsy rate, and positive predictive value of biopsy (PPV3) were compared between DM and DBT with use of adjusted multivariable logistic regression models. Results A total of 2 528 063 screening mammograms from 1 100 447 women (mean age, 57 years ± 10 [SD]) were included. In crude analyses, DBT (1 693 727 screening mammograms vs 834 336 DM screening mammograms) demonstrated lower RR (10.3% [95% CI: 10.3, 10.4] for DM vs 8.9% [95% CI: 8.9, 9.0] for DBT; P < .001) and higher CDR (4.5 of 1000 screening mammograms [95% CI: 4.3, 4.6] vs 5.3 of 1000 [95% CI: 5.2, 5.5]; P < .001), PPV1 (4.3% [95% CI: 4.2, 4.5] vs 5.9% [95% CI: 5.7, 6.0]; P < .001), and biopsy rates (14.5 of 1000 screening mammograms [95% CI: 14.2, 14.7] vs 17.6 of 1000 [95% CI: 17.4, 17.8]; P < .001). PPV3 was similar between cohorts (30.0% [95% CI: 29.2, 30.9] for DM vs 29.3% [95% CI: 28.7, 29.9] for DBT; P = .16). After adjustment for age, breast density, site, and index year, associations remained stable with respect to statistical significance. Conclusion Women undergoing digital breast tomosynthesis had improved screening mammography outcomes compared with women who underwent digital mammography. © RSNA, 2023 Supplemental material is available for this article.

OBJECTIVE: The purpose of this pictorial essay is to review the imaging findings of normally and abnormally positioned Essure permanent birth control devices across the different imaging techniques and to show common sites of device migration. CONCLUSION: The Essure device is easily visualized on all imaging techniques, and radiologists should be familiar with its appearance and be able to identify cases of device migration on ultrasound and hysterosalpingography that would suggest malfunction.

OBJECTIVE: To determine the frequency, type, and results of pediatric ophthalmology service consultations at a tertiary care children's hospital and to offer advice as to the timing of the initial consultation based on the patient's diagnosis and likelihood of ocular disease, METHOD: A retrospective evaluation of inpatient ophthalmology consultations from September 1, 2003, to August 31, 2004, at Texas Children's Hospital was conducted. Patients were identified using the Current Procedural Terminology listing of billing codes for various levels of service for new initial inpatient consultations. RESULTS: During the 1-year period, 445 new inpatient consultations were requested from the pediatric ophthalmology service, primarily to rule out ophthalmic problems or manifestations (55.9%) and to evaluate ocular complaints or ocular abnormalities as noted by the primary team (44.1%). Of the 445 patients, 215 (48.3%) were found to have ocular abnormalities and 230 (51.7%) had no ocular abnormalities at the time of initial consultation. CONCLUSION: Patients with ocular signs or symptoms of disease should receive urgent ophthalmic consultation. Consideration should be given to the usefulness of urgent consultations in patients suspected of having fungemia, sepsis, and headache.
