Is it time to individualize CT lung screening intervals?
By Abraham Kim
Wednesday, December 4 | 10:50 a.m.-11:00 a.m. | SSK05-03 | Room N229Tailoring the interval between baseline and follow-up CT lung screening exams based on an individual's risk of lung cancer could safely reduce the rate of unnecessary screening exams, say researchers from Italy.

Math model optimizes CT radiation for liver cancer
By Abraham Kim
Wednesday, December 4 | 10:30 a.m.-10:40 a.m. | SSK18-01 | Room E353CResearchers from Duke University have developed a mathematical model that can calculate the ideal CT radiation dose for liver cancer detection by weighing the potential harms of CT radiation against the risk of an incorrect diagnosis.

How effective is Lung-RADS for subsolid lung nodules?
By Abraham Kim
Wednesday, December 4 | 10:30 a.m.-10:40 a.m. | SSK05-01 | Room N229Current management guidelines from the Lung Imaging Reporting and Data System (Lung-RADS) slightly underestimate the malignancy of subsolid nodules found on CT lung cancer screening exams and may need to be revised, according to this study to be presented on Wednesday.

AI algorithm makes CAC viable on ultralow-dose CT
By Abraham Kim
Wednesday, December 4 | 10:30 a.m.-10:40 a.m. | SSK03-01 | Room E351Researchers from Israel have developed a denoising artificial intelligence (AI) algorithm that can make coronary artery calcium (CAC) scoring viable on ultralow-dose CT scans.

Photon-counting CT cuts radiation dose by roughly 80%
By Abraham Kim
Tuesday, December 3 | 3:00 p.m.-3:10 p.m. | SSJ22-01 | Room N226Photon-counting CT can match the image quality of conventional sinus and temporal bone CT at approximately one-sixth the radiation dose, according to researchers from the Mayo Clinic in Rochester, MN.

CCTA adds value to ischemic stroke evaluation
By Abraham Kim
Monday, December 2 | 3:40 p.m.-3:50 p.m. | SSE06-05 | Room E353AAcquiring coronary CT angiography (CCTA) in addition to head CT for patients suspected of having an acute ischemic stroke can help identify potential sources of cardioembolic stroke while also providing insight into the patients' risk of coronary artery disease, according to this study to be presented on Monday.

FFR-CT values vary by coronary artery segment measured
By Abraham Kim
Monday, December 2 | 11:40 a.m.-11:50 a.m. | SSC01-08 | Room S402ABFractional flow reserve CT (FFR-CT) values measured in the distal segment of the coronary arteries were markedly lower than those measured in the proximal and mid segments of the same arteries in a study by researchers from South Carolina.

FFR-CT, CCTA bolster emergency chest pain evaluation
By Abraham Kim
Monday, December 2 | 11:20 a.m.-11:30 a.m. | SSC04-06 | Room S102CDThe combination of fractional flow reserve CT (FFR-CT) and conventional coronary CT angiography (CCTA) proved to be effective at ruling out major adverse cardiac events for emergency patients with acute chest pain in this study to be discussed on Monday.

New CT guidance method improves lung nodule localization
By Abraham Kim
Sunday, December 1 | 11:45 a.m.-11:55 a.m. | SSA24-07 | Room S404CDResearchers from Michigan have developed a minimally invasive CT-guided technique for preoperatively marking lung nodules as accurately as standard techniques, which they will detail in their upcoming Sunday presentation.
