CT lung cancer screening evolves at major academic centers
Monday, November 30 | 11:20 a.m.-11:30 a.m. | RC201-11 | Room S406BMajor changes have come to CT lung cancer screening in the past two years, and the results of a survey of major academic centers highlights both modest increases in screening volumes and a move away from self-pay screening.

How many CT lung cancer screening patients return after the 1st scan?
Monday, November 30, 2015 |10:50 a.m.-11:00 a.m. | RC201-09 | S406B In this study, researchers assessed patient compliance with follow-up recommendations in a CT lung cancer screening program.

Tin filters and lung nodule CT at x-ray exposure levels: Accurate?
Thursday, December 3 | 11:10 a.m.-11:20 a.m. | SSQ19-05 | Room S403BHow well does CT equipped with a tin filter measure lung nodule volumes at radiation dose levels similar to those of a chest x-ray? Pretty well, most of the time, Mayo Clinic researchers will report in this Thursday presentation.

Noncontrast head CT takes on small hyperdensities
Wednesday, December 2 | 3:50 p.m.-4:00 p.m. | SSM07-06 | Room S403BIn the emergency room, noncontrast head CT scans often reveal hyperdensities that could represent small parenchymal hemorrhages or calcifications. Much of the time, but not always, the two can be differentiated by morphology and location. But is the standard practice of waiting six hours to repeat the head CT scan to assess stability the best way to solve the remaining mysteries?

Monoenergetic images vs. calcium blooming in CCTA
Wednesday, December 2 | 11:50 a.m.-12:00 p.m. | SSK04-09 | Room S504ABCalcium blooming in coronary CT angiography (CCTA) images makes calcium appear larger than its actual size, exaggerating the extent of luminal stenosis and producing false-positive tests, which can lead to inappropriate clinical management, according to this study to be presented on Wednesday.

For ischemic stroke, CT perfusion boosts detection in posterior circulation
Tuesday, December 1 | 3:10 p.m.-3:20 p.m. | SSJ18-02 | Room N226There is still no consensus about the best way to image the posterior circulation in the setting of ischemic stroke, but researchers in Münster, Germany, have found significant value in CT perfusion.

Radiology's future combines tech innovation and productivity tools
Tuesday, December 1 | 1:30 p.m.-2:45 p.m. | PS30C | Arie Crown TheaterWhat does the future hold for radiology? Get ready for a cascade of sometimes conflicting trends -- all leading toward a more complex and better diagnosed future, according to a Tuesday plenary talk by radiology luminary Dr. James Thrall.

DECT technique separates benign from malignant lung nodules
Tuesday, December 1 | 11:50 a.m.-12:00 p.m. | SSG03-09 | Room S404CDWhile CT is good at detecting lung nodules, PET/CT is better at determining whether they are malignant or benign. Researchers from Kobe, Japan, wanted to see if their CT technique, known as dual-point contrast-enhanced dual-energy CT (DECT), could rival PET/CT for predicting malignancy.

Phase-contrast CT technique reveals hidden image information
Tuesday, December 1 | 11:40 a.m.-11:50 a.m. | SSG14-08 | Room S403BNew developments in phase-contrast CT imaging have some investigators intrigued about the potential of x-ray-based techniques to reveal previously unseen information. Researchers from Emory University will share their thoughts in this Tuesday session.

What's the minimum CT dose for hepatic metastasis detection?
Tuesday, December 1 | 11:20 a.m.-11:30 a.m. | SSG05-06 | Room E352How low can the CT radiation dose go for hepatic metastasis detection when using advanced iterative reconstruction? Investigators from the Mayo Clinic in Rochester, MN, wanted to see how low advanced iterative reconstruction would take them.

Images of a 39-year-old who underwent screening mammography. Right craniocaudal (left) and mediolateral oblique (middle) views from preoperative mammography show suspicious grouped fine pleomorphic calcifications (arrows). After biopsy showed ductal carcinoma of situ (DCIS), patient underwent breast-conserving surgery, yielding final diagnosis of ductal carcinoma in situ (intermediate grade, hormone receptor positive). (Right) Screenshot of an output of a commercial AI tool applied to preoperative mammography. AI detected right breast lesion with score of 95% on both views (concentric colored circles). Present study’s reviewing radiologist deemed AI marking to correspond with site of DCIS.

Axial contrast-enhanced CT scan in a 28-year-old premenopausal woman shows an incidentally detected solid-appearing left ovarian lesion (solid arrow) anterior to the uterus (U), associated with trace ascites in the right adnexa and cul de sac (dashed arrows). At pathologic analysis, this was shown to be ovarian dysgerminoma. Two readers misdiagnosed this lesion, one as a leiomyoma and one as an ovarian fibroma.
