Automated breast ultrasound matched handheld cancer detection with fewer callbacks in dense breasts

The edition in brief

In 25,328 supplemental ultrasound examinations in women with dense breasts at 27 US facilities, automated breast ultrasound was associated with fewer abnormal interpretations (14.9% vs 19.2%) and far fewer short-interval follow-up recommendations (3.0% vs 14.6%) than handheld ultrasound, with no apparent difference in cancer detection. Across 23 urgent care centres, 0.82% of radiographs for low-acuity low back pain were followed by emergency CT or MRI within 30 days, and one was judged a true miss; guidelines still advise against routine imaging without red flags. In 48 patients with myositis-associated interstitial lung disease, a low-dose photon-counting CT protocol (CTDIvol 0.77 vs 5.40 mGy) gave deep-learning quantification within 1% of standard dose. And in 92 intra-arterial liver procedures, dual-phase angio-CT had a lower 3D dose than cone-beam CT, but the total-dose difference did not survive correction for conversion uncertainty.
