3D printers help build a better cranial nerve
Researchers have created a high-resolution model of a 3D-printed brain and skull base from CT and MR images that details the cranial nerves in ways that outperform standard diagnostic images. The complex neuroanatomy of the nerves can be better understood and depicted by the use of highly customizable 3D-printed models, according to a report in the Journal of Digital Imaging.

3DHeals conference explores 3D printing and more
3D printing is revolutionizing medicine -- and radiology with it. But what's the best way to learn about this emerging discipline? The 3DHeals International Conference, being held in San Francisco on April 20, will explore 3D printing in healthcare with an eye on virtual reality, augmented reality, and artificial intelligence.

ACC: CT detects blood clots that reduce valve motion
CT detects small clots surrounding valve leaflets after transcatheter aortic valve replacement that are missed on echocardiography studies, concludes new research presented at the just-concluded American College of Cardiology (ACC) meeting in Washington, DC. Reduced valve motion after the procedure may be a sign of the condition, the researchers said.

Chest CT with iterative recon achieves x-ray doses
VIENNA - Chest CT scans acquired at radiation doses as low as an x-ray showed lesions of all kinds conspicuously, using the latest dual-source CT scanner and iterative reconstruction. Individualized approaches tailored to specific lesion types cut the dose even further, researchers said on Friday at ECR 2017.

Artifact reduction algorithm boosts utility of 4D CT
Four-dimensional CT images can improve radiation therapy planning in the upper thorax and abdomen, but motion artifacts often make the images nondiagnostic. New algorithms that provide deformable registration and respiratory motion simulation clear up the picture.

Low-dose CT ties emphysema to mortality in previous smokers
By Amerigo Allegretto
Study findings highlight the clinical relevance of CT-diagnosed emphysema.
September 9, 2025
Representative axial images of mild, moderate, and severe emphysema at baseline low-dose CT (LDCT). Participants were categorized as having no emphysema or mild, moderate, or severe emphysema. When present, emphysema was mild if no distinct regions of reduced attenuation were visible on the CT scan, but vascular splaying indicates parenchymal expansion, or if only occasional discrete low-attenuation regions were observed. Moderate emphysema was defined by the presence of identifiable low-attenuation regions affecting less than half of the lung parenchyma, whereas severe emphysema was defined by the presence of identifiable low-attenuation regions that involved more than half of the lung parenchyma. A scoring system from 0 to 3 was applied, corresponding to none, mild, moderate, and severe emphysema, respectively. Yellow circle indicates the extent of emphysema. (A) A 67-year-old man with mild emphysema at baseline LDCT in 2002. Baseline LDCT scan shows vascular splaying, suggesting parenchymal expansion due to emphysema and occasional discrete low-attenuation regions. The participant ultimately died of cardiovascular disease 15.4 years (184.2 months) later. (B) A 69-year-old man with moderate emphysema at baseline LDCT in 2007. The participant died of cardiovascular disease 1.8 years (21.9 months) later. Identifiable low-attenuation regions affected less than half of the lung parenchyma. (C) An 85-year-old woman with severe emphysema at baseline LDCT in 2006. After 5.5 years (65.5 months) of follow-up, the participant died due to chronic obstructive pulmonary disease–related causes. Identifiable low-attenuation regions involved more than half of the lung parenchyma.
