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.

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.
