Jul 18, 2025

The Society for Cardiovascular Computed Tomography (SCCT) is holding its annual meeting July 17 to 20 in Montreal, and AuntMinnie spoke to the society's incoming president, Kavitha Chinnaiyan, MD, of Oakland University William Beaumont School of Medicine in Royal Oak, MI. Chinnaiyan discussed the environmental impact of the modality and the society's efforts to support women-led cardiovascular health research.

AI boosts brain aneurysm detection on CT angiography

AI preferentially detected smaller aneurysms (< 3 mm), while radiologists more often identified larger aneurysms (3 to 5 mm and > 5 mm).

Chest CT muscle attenuation predicts future bone density loss

Muscle and bone loss commonly coexist with aging, but potential links between paraspinal muscle and thoracic vertebral bone mineral density loss remain poorly understood

September 15, 2026

Study overview. (A) Volumetric segmentation of the paraspinal musculature was performed for 1,316 participants. (B) Manual segmentation was performed, the results were compared with the volumetric segmentation results, and the Dice score and the intersection over union were calculated. (C) The three-dimensional segmentations from T1 through T10 were individually extracted and combined into a single volume for analyses. (D) Muscle volume and median muscle attenuation were derived from the segmentation volumes. (E) Analyses were performed to assess the correlation of the paraspinal muscle attenuation and volume with the bone mineral density and the ability to predict vertebral fractures. NIFTI = Neuroimaging Informatics Technology Initiative, 3D = three-dimensional.

AI cuts chest CT reporting time

Exploratory modeling suggested an approximate reduction of 0.5 full-time equivalent radiologist workload.

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?

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.
