CCTA can cut complications and hospital stays

Coronary CT angiography (CCTA) is a safe gatekeeper for cardiac catheterization, reducing the need for intervention, boosting the diagnostic yield of interventions, and trimming minor procedural complications, reported German investigators writing in BMJ.

Lung nodule assessment model sorts benign from malignant

Friday, December 2 | 10:40 a.m.-10:50 a.m. | SST03-02 | Room E451BIs there a better tool than the radiologist's eye to determine whether a CT-detected lung nodule is benign or malignant? There might be. In this study, researchers put a promising nodule discrimination model in a controlled observer study.

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.
