New CT guidance method improves lung nodule localization
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.

DECT more cost-effective than CT, MRI for kidney lesions
Sunday, December 1 | 11:35 a.m.-11:45 a.m. | SSA11-06 | Room N230BDual-energy CT (DECT) may be more cost-effective than conventional CT or MRI for evaluating incidentally detected renal lesions, based on simulations from an analytical model that serve as the subject of this study to be presented on Sunday.

CT whole-heart volume predicts adverse cardiac events
Sunday, December 1 | 11:05 a.m.-11:15 a.m. | SSA03-03 | Room S105ABIndividuals with a small 3D whole-heart volume, as calculated on CT scans, have an increased risk of major adverse cardiac events, compared with those with a normal or large heart volume, according to researchers from Harvard Medical School.

Road to RSNA 2019: CT Preview
The vast number of CT presentations at RSNA 2019 is a testament to the modality's resilience, its value, and its adaptability. This year's presentations will reaffirm the utility of tried-and-true imaging techniques and also feature relatively new technologies that have already begun reshaping the approach radiologists take to common clinical applications.

CT lung screening proves cost-effective even at older ages
A cost analysis of well-established CT lung cancer screening guidelines confirmed that screening remains cost-effective even at the oldest upper age limits, with screening of older people incurring more costs but offering greater reductions in mortality risk. The findings were published online November 4 in Annals of Internal Medicine.

Reversed halo sign on chest CT linked to septic PE
The presence of a reversed halo sign on chest CT scans is indicative of septic pulmonary embolism (PE) in patients with intravenous substance use disorder, according to a study published online October 31 in the American Journal of Roentgenology.

Could cold, hard cash reduce unnecessary head CT scans?
Offering financial incentives like cash to emergency patients with minor traumatic brain injury to convince them to skip scans that might not be medically indicated may help reduce the rate of unnecessary head CT exams, according to an article published in the October issue of Academic Emergency Medicine.

Life expectancy model refines CT lung screening criteria
Researchers from the U.S. National Institutes of Health have developed a prediction model that determines an individual's eligibility for CT lung cancer screening based on life years gained. The model may be a more effective alternative to traditional screening criteria, according to an October 22 article in the Annals of Internal Medicine.

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.

Could AI scoring help with managing 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.
