ASTRO: SABR is effective for oligometastatic cancers
Stereotactic ablative radiotherapy (SABR) can greatly increase how long oligometastatic patients survive and doubles how long they live without cancer, according to new research presented at this week's American Society for Radiation Oncology (ASTRO) meeting.

DBT spots 34% more breast cancers than mammography
One-view digital breast tomosynthesis (DBT) detects 34% more breast cancers than traditional mammography -- with a majority of the detected tumors proving to be invasive cancers, according to a large clinical study in Sweden.

Cancer death disparities linked to poverty, lifestyle
Yale researchers have found that disparities in cancer death rates are linked to poverty and lifestyle factors across the U.S. The factors may provide public health experts with specific targets for potentially reducing such disparities, the researchers said.

Drop ultrasound contrast agent warning, society says
The International Contrast Ultrasound Society (ICUS) has filed a petition with the U.S. Food and Drug Administration urging the agency to remove boxed warnings from ultrasound contrast agents. ICUS believes the warnings are obsolete in light of clinical experience and recently released data on the safety of the agents.

Study claims breast screening does not reduce mortality
The findings of a new Danish-Norwegian study are reviving the claim that the recent drop in breast cancer mortality is not due to mammography screening but rather the result of improved treatment. The authors assert it's time to consider alternatives to mammography screening -- such as breast palpation by physicians.

Images of a 39-year-old who underwent screening mammography. Right craniocaudal (left) and mediolateral oblique (middle) views from preoperative mammography show suspicious grouped fine pleomorphic calcifications (arrows). After biopsy showed ductal carcinoma of situ (DCIS), patient underwent breast-conserving surgery, yielding final diagnosis of ductal carcinoma in situ (intermediate grade, hormone receptor positive). (Right) Screenshot of an output of a commercial AI tool applied to preoperative mammography. AI detected right breast lesion with score of 95% on both views (concentric colored circles). Present study’s reviewing radiologist deemed AI marking to correspond with site of DCIS.

Axial contrast-enhanced CT scan in a 28-year-old premenopausal woman shows an incidentally detected solid-appearing left ovarian lesion (solid arrow) anterior to the uterus (U), associated with trace ascites in the right adnexa and cul de sac (dashed arrows). At pathologic analysis, this was shown to be ovarian dysgerminoma. Two readers misdiagnosed this lesion, one as a leiomyoma and one as an ovarian fibroma.

Super-resolution deep learning reconstruction improves CCTA
By Will Morton
The commercially available image reconstruction algorithm outperformed standard hybrid iterative reconstruction for assessing coronary stenosis.
February 10, 2026
Images from two representative cases. (A-C) Images in an 82-year-old man with a calcified plaque in the proximal segment of the left anterior descending artery. (A, B) Curved planar reconstruction images from CCTA with (A) hybrid iterative reconstruction (HIR) and (B) super-resolution deep learning reconstruction (SR-DLR) show that the measured PDS was 66% for the HIR image and 42% for the SR-DLR image. (C) Quantitative analysis of the invasive coronary angiography (ICA) image (reference standard) revealed a PDS of 34% (arrow). (D-F) Images in a 37-year-old woman with a noncalcified plaque in the middle segment of the left circumflex artery. (D, E) Curved planar reconstruction images from CCTA with (D) HIR and (E) SR-DLR show that the measured PDS was 47% for the HIR image and 80% for the SR-DLR image. (F) Quantitative analysis of the ICA image revealed a PDS of 72% (arrow). Blue, red, and yellow lines in A, B, D, and E represent the proximal reference point, stenosed lesion, and distal reference point, respectively, and the insets show the corresponding cross-sectional images.
