Contrast CT distinguishes benign from malignant adrenal masses
Sunday, November 25 | 10:45 a.m.-10:55 a.m. | SSA09-01 | Room E351Adrenal masses are commonly seen at contrast-enhanced CT and most are benign, but when confirmation is critical, additional exams such as unenhanced CT, MR, washout CT, and PET are often ordered to make the call. But can contrast-enhanced CT do the job reliably without more tests?

Road to RSNA 2012: CT Preview
RSNA 2012 caps an extraordinary year for CT fans who like their technology high and their radiation doses low. The CT-focused scientific sessions at this year's show explore a broad array of CT topics that are driven, more than anything, by the need to get more image information with less radiation.

Mortality down in Japan after CT lung cancer screening begins
Results from a lung cancer screening program in Japan suggest that implementation of low-dose chest CT screening in the community may decrease lung cancer mortality within a few years after it's introduced -- at levels comparable to those found in the National Lung Screening Trial in the U.S., according to a study published this month in Lung Cancer.

Sharper image: 3D phase-contrast tomo shows smaller breast tumors
Researchers from the University of California, Los Angeles (UCLA), Germany, and France have collaborated to produce ultrasharp 3D breast images with a technique that delivers less radiation than a mammogram, according to an article published online in the Proceedings of the National Academy of Sciences.

CONFIRM study confirms gateway role for cardiac CTA
In a study of more than 15,000 patients who underwent coronary CT angiography (CCTA), few individuals with mild or moderate disease needed invasive procedures, confirming CT's role as a cost-efficient gateway exam for patients with suspected coronary artery disease, researchers wrote in the Journal of the American College of Cardiology.

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.
