Air pollution tied to worse coronary disease on CT, especially in women
By Kate Madden Yee
The strongest effects of pollution exposure is seen in women, even at moderate levels typical of high-income countries.
June 9, 2026
Axial images from unenhanced calcium score cardiac CT (left) and curved planar reformation images from CT angiography (right) show that higher long-term exposure to air pollution is associated with greater coronary artery calcium and more obstructive coronary artery disease (CAD). Top row: Images in a 68-year-old male patient with higher 10-year mean ambient air pollution exposure (7.9 μg/m3 for particulate matter measuring ≤2.5 μm in diameter [PM2.5] and 17.4 parts per billion [ppb] for NO2) with extensive CAD (coronary artery calcium score [CACS] >1,000 and obstructive CAD [≥70% diameter stenosis]). Bottom row: Images in a 57-year-old female patient with lower 10-year mean ambient air pollution exposure (6.3 μg/m3 for PM2.5 and 4.6 ppb for NO2) with no CAD (CACS = 0 and no obstructive stenosis).

AI detects lung cancer nodules well but shows low specificity

CT collateral status may predict outcomes in stroke patients
By Will Morton
The findings have implications for future research to determine which stroke patients with medium-vessel occlusion benefit from EVT.
May 26, 2026
Exemplary cases from the ESCAPE-MeVO trial illustrating good, moderate, and poor collateral status at baseline multiphase CT angiography (CTA). (A) Sagittal image shows a left anterior middle cerebral artery medium-vessel occlusion (MeVO) with a calcified thrombus (arrow). (B–D) Axial images show the (B) arterial, (C) peak venous, and (D) delayed venous phases of the baseline multiphase CTA examination. The affected brain parenchyma is highlighted by the dashed outline. The collateral status is good, with early filling of more than 50% of the leptomeningeal collaterals compared with the contralateral side in the arterial phase (B), and there is no delayed washout in the peak venous (C) or delayed venous phase (D). (E) Sagittal image shows a left anterior middle cerebral artery MeVO (arrow). (F–H) Axial images show the (F) arterial, (G) peak venous, and (H) delayed venous phases of the baseline multiphase CTA examination. The affected brain parenchyma is highlighted by the dashed outline. The collateral status is moderate (more than 25% but less than 50% filling of the leptomeningeal collaterals in the affected territory compared with the contralateral side) on the arterial (F) and peak venous (G) phase, and there is delayed washout in the late venous phase (H). (I) Sagittal image shows a posterior dominant middle cerebral artery MeVO (arrow). (J–L) Axial images show the (J) arterial, (K) peak venous, and (L) delayed venous phases of the baseline multiphase CTA examination. The affected brain parenchyma is highlighted by the dashed outline. The collateral status is poor, with almost no collateral filling.
