Quality improvement effort slashes CT radiation dose
A simple and cost-effective intervention led to reductions in CT radiation dose as high as 58% -- without a notable drop in image quality -- for a cohort of nearly 1 million individuals from 100 facilities across the globe in a new study. The findings were published online March 30 in JAMA Internal Medicine.

AR, 3D printing set to improve cranial surgery outcomes
Researchers from Brazil have developed a way to visualize and interact with patient-specific anatomy using augmented reality (AR) and 3D printing. They describe how the technique could improve preoperative planning for cranial surgery and patient outcomes in an article in the March issue of Neurosurgical Focus.

RSNA proposes standardized CT reporting for COVID-19
CT is currently not recommended as a first-line diagnostic or screening tool for COVID-19, but its use to understand and manage the disease continues to grow. In response, the RSNA proposed standardized CT reporting language for COVID-19 in a special report posted on March 25 in Radiology: Cardiothoracic Imaging.

Imaging confirms coronavirus transmits from mother to fetus
The combination of CT, x-ray, and DNA testing confirmed that the novel coronavirus was transmitted from pregnant women to nearly 10% of newborns in a new study, published online March 26 in JAMA Pediatrics. The findings underscore the need for strict infection control measures for this vulnerable population.

CT shows parallels between vaping lung injury, COVID-19
COVID-19 and vaping-related lung injury share many features on CT, but the imaging modality's role in diagnosing the diseases has taken diverging paths, according to a March webinar hosted by the American Roentgen Ray Society.

CT depicts how COVID-19 abnormalities change over time
CT scans revealed rapid progression of abnormalities in COVID-19 patients, typically peaking on the 10th day from symptom onset, in a new study published March 19 in Radiology. The persistence of CT abnormalities through the final stages of disease underscores the need to monitor patients well after discharge.

CT details effect of COVID-19 on pregnant women
Does COVID-19 have a more devastating effect on pregnant women? Is the disease passed down to newborns after birth? What's the best management strategy for this vulnerable population? Researchers from China addressed these and similar questions in a March 18 study published in the American Journal of Roentgenology.

Women have more chest pain despite less stenosis on CCTA
Women with coronary artery disease are much more likely to have frequent chest pain than men, despite having less extensive disease on coronary CT angiography (CCTA) and less severe ischemia on stress imaging, according to a study.

ACR recommends sparing use of CT for COVID-19
CT should not be used as a first-line diagnostic or screening tool for the novel coronavirus disease (COVID-19), according to a March 11 statement by the American College of Radiology (ACR). The statement covers the appropriate use of chest x-ray and CT for the screening, diagnosis, and management of COVID-19.

3D MRI technique helps plan treatment for pediatric heart conditions
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.

Could AI scoring help with managing 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

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.
