CT best for diagnosing suspected wooden foreign objects in the eye
By Kate Madden Yee
CT imaging is best for diagnosing suspected intraorbital wooden foreign bodies, although MR imaging does offer valuable supplementary information.
February 20, 2025
A 7-year-old boy, imaged 15 hours post-injury. Axial CT images with soft tissue windows (WW/WL=350/50) (a) reveal a rod-shaped foreign body (white arrow) situated along the course of the right inferior rectus muscle. The soft tissue window demonstrates that the foreign body exhibits attenuation similar to orbital emphysema. Axial CT images (WW/WL=1000/−200) at the same level (b) show that the attenuation of the foreign body (white arrow) is markedly different from that of the air in the sinuses.

Epicardial adipose tissue on LDCT tied to cardiovascular mortality risk
By Amerigo Allegretto
Epicardial adipose tissue (EAT) on low-dose CT (LDCT) images is tied to higher cardiovascular mortality risk in lung cancer patients.

Representative examples show EAT changes (ΔEAT) between baseline and two-year follow-up CT scans in participants who survived (typical changes) and increasing and decreasing EAT in participants who died.
