Example of AI-assisted pulmonary nodule detection and longitudinal volumetric assessment in a 65-year-old woman with peripheral arterial disease, a 24-pack-year smoking history, emphysema, and a family history of lung cancer. An incidental 8.5-mm right lower lobe pulmonary nodule is identified at CT angiography of the abdomen in July 2022 but does not receive follow-up. Subsequent imaging demonstrates interval growth, and CT-guided biopsy confirms stage IA lung adenocarcinoma. Contrast-enhanced axial chest CT images obtained on February 2, 2024, before robotic-assisted thoracoscopic segmentectomy, show a 12.1-mm spiculated right lower lobe pulmonary nodule. (A) Conventional contrast-enhanced axial chest CT image without AI assistance shows a 12.1-mm spiculated right lower lobe pulmonary nodule. (B) Corresponding CT image with AI-assisted pulmonary nodule detection, automated segmentation, and quantitative nodule assessment identifies a solid pulmonary nodule (nodule #1) measuring 13 × 8 (11) mm, with a volume of 739 mm3, a 45% volumetric increase compared with the previous contrast-enhanced chest CT performed on October 9, 2023 (510 mm3), and an estimated volume doubling time (VDT) of 216 days. (C) AI-generated longitudinal nodule analysis displays automated segmentation of the current (February 2, 2024) and previous (October 9, 2023) CT examinations, 3D nodule reconstruction, and quantitative volumetric assessment for longitudinal follow-up. The AI interface is displayed in the original software language (Dutch).

PCCT on par with MRI for diagnostic breast imaging
By Amerigo Allegretto
PCCT performed similarly to MRI for characterizing breast lesions and finding additional lesions.
September 1, 2026
Detection and extent of BI-RADS suspicious calcifications (amorphous, coarse heterogeneous, fine pleomorphic, and fine linear or fine linear branching) at axial photon-counting CT (PCCT) versus full-field digital mammography (first three images, craniocaudal view; last image, mediolateral oblique view). Calcifications found on mammography showed only partial visualization at ultrahigh-resolution PCCT (0.2 mm), while amorphous calcifications could not be distinguished from image noise. Corresponding abnormal enhancement was clearly depicted on contrast-enhanced PCCT images.

Is nitroglycerin necessary prior to photon-counting CT?
By Will Morton
Sublingual nitroglycerin is routinely administered before CCTA to induce coronary vasodilation.
August 27, 2026
Representative case from the non-nitroglycerin cohort. A 92-year-old man who did not receive sublingual nitroglycerin because of severe aortic stenosis. The Agatston coronary artery calcium score was 5438. (A) Curved multiplanar reformatted CCTA image reconstructed at 0.4-mm slice thickness using a Bv60 kernel and QIR strength 3 demonstrates diffuse multifocal mild luminal stenoses related to extensive calcified atherosclerotic plaque. (B) Invasive coronary angiography confirmed multifocal mild stenoses without evidence of obstructive coronary artery disease.
Sustainability efforts should look to state power grids

Variation in grid carbon intensity by state drives per-beneficiary greenhouse gas emissions from MRI and CT use.

Choropleth map of state-level imaging-associated greenhouse gas emissions per 1,000 Medicare Part B fee-for-service beneficiaries in 2022. Darker shades indicate higher per-beneficiary greenhouse gas emissions. District of Columbia (not shown) is in 3-4 MTCO2e per 1,000 range. MT CO₂e = metric tons of carbon dioxide equivalent
CT reveals progressive growth pattern in incidental lung nodules
By Will Morton
This pattern is most associated with a family history of lung cancer.
August 25, 2026
Serial axial chest CT scans demonstrating the longitudinal evolution of small pure ground-glass nodules (pGGNs) incidentally detected during a routine wellness assessment. (A) Images in a 37-year-old woman with a family history of lung cancer show a nodule with the progressive growth pattern (box). The baseline CT scan, obtained in October 2017, demonstrates a pure ground-glass nodules in the right lower lobe. Consecutive CT scans obtained from 2017 to 2022 show the continuous enlargement of the nodule during active surveillance. The maximum diameter of the nodule increased from 5.6 mm in 2017 to 10.2 mm in 2022. (B) Images in a 45-year-old man show a nodule with the indolent growth pattern (box). The baseline CT scan, obtained in April 2018, demonstrates a pure ground-glass nodules in the left lower lobe. Consecutive CT scans obtained from 2019 to 2023 show that the nodule remained radiographically stable during CT surveillance. The maximum diameter of the nodule was 5.4 mm in 2018 and 6.1 mm at the final surveillance scan in 2023.
