AI plus CCTA cuts plaque analysis time, predicts cardiac event risk
By Kate Madden Yee
A deep-learning model quantifies coronary plaque volume from coronary CT angiography (CCTA) images.
April 21, 2026
Two representative cases demonstrate the performance of PlaqueSegNet for coronary plaque segmentation. (A–D) Coronary CT angiography (CCTA) and intravascular US (IVUS) images in a 65-year-old male patient with chest pain for two months show plaque. (A) Cross-sectional IVUS image shows a lipid-rich plaque (hypoechoic, arrows). (B) Axial and (C) cross-sectional CCTA images show the same plaque (low-attenuation area, yellow line and arrows) in the proximal left anterior descending artery. (D) PlaqueSegNet segmentation of the noncalcified plaque (yellow shading) and coronary lumen (green shading) in the cross-sectional image. (E–G) CCTA images in a 57-year old female patient with chest pain for three months show multiple plaques. (E) Volume-rendered CCTA image of the coronary tree shows PlaqueSegNet plaque segmentation (yellow) in the right and left coronary arteries. (F, G) PlaqueSegNet segmentation delineates a mixed plaque (yellow shading) and coronary lumen (green shading) in the left main artery and proximal-to-mid left anterior descending artery.

How best to characterize CT lung findings after radiation therapy
By Kate Madden Yee
Serial chest CT is cornerstone of post-RT surveillance, but "accurate interpretation is critical to avoid misdiagnosis."
April 17, 2026
Acute radiation-induced pneumonitis after SBRT (65 Gy, four fractions) in a 53-year-old woman with leiomyosarcoma of the uterus with a left lower lobe metastasis manifesting as a small nodule (not shown). (A) Axial dosimetric reconstruction of a CT image obtained for SBRT planning shows the metastasis receiving the maximal isodose (6500 cGy). (B) Axial CT image obtained 12 months after completion of RT shows focal ground-glass and consolidative opacities confined to the treatment plan (arrow). Note that acute lung injury with SBRT typically manifests later than with conventional RT (i.e., >12 weeks after completion of therapy), and in 25% of patients, the first CT manifestations occur more than one year after completion of RT.
