Saliency maps using Grad-CAM++ (E and H) show the model’s point of interest in chest radiographs (C and F) of patients with achalasia. The model’s point of interest is highlighted with red, yellow, and green. In both the upper and lower panels (E and H), the point of interest is located in a region around the upper esophagus that corresponds to an air esophagogram and/or air-fluid level in the esophagus in the barium esophagogram (D and G).

Diagnostic transverse ultrasound image of the left breast in a 64-year-old woman shows irregular hypoechoic nonparallel mass with indistinct margins corresponding to palpable finding, assessed as BI-RADS category 4. Both readers assessed mass as having associated echogenic rind with complete circumferential extent (arrowheads). Ultrasound-guided biopsy of mass yielded diagnosis of invasive ductal carcinoma (intermediate grade, luminal A molecular subtype, no lymphovascular invasion).

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.
