How to image obstructive coronary artery disease
Thursday, December 1 | 8:30 a.m.-10:00 a.m. | RC603 | Room E351This review course gets to the heart of coronary disease, the malady underlying most cardiac morbidity, mortality, and expense. It includes a state-of-the-evidence talk, a discussion of CT myocardial perfusion imaging, and even two talks on MRI of coronary disease.

Is SSDE best for tracking dose in low-dose CT lung cancer screening?
Thursday, December 1 | All day | PH107-ED-X | Lakeside, PH CommunityCan size-specific dose estimates (SSDEs) be considered the preferred dose index for detectability in lung cancer screening? This collaborative exhibit between Japanese and U.S. researchers explores the suitability of SSDE for dose assessment in lung cancer screening.

Volume wins again in epidural spine metastases
Wednesday, November 30 | 3:20 p.m.-3:30 p.m. | SSM18-03 | Room N229Epidural spine metastases are defined as a radiologic critical finding because any delay in reporting may result in substantially increased morbidity. But how can imaging be optimized to find more of them?

Time of detection matters in lung nodule malignancy
Wednesday, November 30 | 3:00 p.m.-3:10 p.m. | SSM05-01 | Room S404ABIn a study that analyzed the risk of malignancy of screen-detected solid lung nodules, researchers from the Netherlands found that nodule size remains by far the most important predictor of malignancy. But when a nodule is discovered also matters.

Perfusion CT predicts treatment response, survival in HCC
Wednesday, November 30 | 10:30 a.m.-10:40 a.m. | SSK06-01 | Room E353ACT perfusion imaging offers early biomarkers for hepatocellular carcinoma (HCC) patients being treated with the kinase inhibitor sorafenib, helping doctors quickly determine who will survive longer and who is not being helped by the drug, say researchers in Japan.

Myocardial fat offers protective shield
Tuesday, November 29 | 3:40 p.m.-3:50 p.m. | SSJ04-05 | Room S504ABMyocardial fat on CT images has long been thought to be a bad thing, so researchers in New York City were surprised to find just the opposite in 1,000 patients: enhanced survival and potentially a readjusted risk profile.

Technique uses CT to assess subchondral bone density
Tuesday, November 29 | 11:30 a.m.-11:40 a.m. | SSG09-07 | Room E450BResearchers from Switzerland have found a way to evaluate bone mineral density in the subchondral bone using high-resolution CT, paving the way to better understanding of osteoarthritis, leading to treatment or a cure.

Organ-based dose modulation tames a high-dose CT exam
Tuesday, November 29 | 11:30 a.m.-11:40 a.m. | SSG04-07 | Room E352An organ-based dose modulation system enables reduction of CT liver doses by one-quarter or more, with no reduction in image quality, say researchers from France.

Study measures accuracy of iodine quantification
Tuesday, November 29 | 11:20 a.m.-11:30 a.m. | SSG12-06 | Room S403BThe accuracy of iodine quantification is becoming a critical question as researchers rely increasingly on dual-energy CT to quantify the composition of scanned materials. Researchers tested three different scanners to find out how well they do the job.

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).
