Risk-based lung cancer screening mitigates healthcare disparities
By Kate Madden Yee
Risk-based lung cancer screening using a model called the PLCOm2012-Update appears to mitigate racial and ethnic disparities and improve screening performance compared with a protocol based on the USPSTF 2021 criteria.

AI model shows promise for interpreting follow-up chest x-rays
By Will Morton
A group in Seoul, South Korea, has developed an AI model that could help reduce radiology workflows by identifying “no changes” in follow-up chest x‑rays.

Example of triage of no change in a pair of chest radiographs in the emergency department. (A) Baseline posteroanterior chest radiograph in a 63-year-old female patient shows a small amount of left (L) pleural effusion and partial atelectasis of the right middle lobe. (B) Follow-up posteroanterior chest radiograph obtained in the same patient 1 day later shows no significant change. (C) Gradient-weighted class activation map shows the algorithm determined no change in the image pair, without relevant highlighting, as the highlighted area is located over the gastroesophageal junction.

Visualization of EigenGradCAM (A) and GradCAM results (B) illustrating association between fracture group classification and DXA image features for moderate fracture risk subjects. Given are the three highest confidence images with labels predicted for correct classifications, which ranged from 85% to 92% confidence. Image courtesy of JBMR Plus.
How does menopause affect women's cerebral blood flow?
By Kate Madden Yee
Arterial spin labeling MRI shows that alterations in women's cerebral blood flow begin during perimenopause and may be due to an increased burden of white-matter hyperintensities.
