Dose experts look at radiation risk, error, and uncertainty
What's the latest on risk from medical radiation? It all depends on the exam and the patient, of course, but knowledge is evolving, and some newer evidence suggests higher risks from smaller doses, according to speakers presenting last Friday at a Washington, DC, symposium.

Radiation symposium: Dose tracking calls for collaboration, technology
Experts from around the world convened in Washington, DC, today for a two-day symposium on finding better ways to track and utilize medical radiation dose. Collaboration is key, speakers said, because the problem of tracking radiation dose is so big that no single country or governmental agency can solve it alone.

Same CCTA results mean different risks in men and women
CHICAGO - Researchers have long known of differences between men and women in the rate of cardiac disease and resulting morbidity, but a new study presented at RSNA 2011 suggests that the same coronary CTA (CCTA) results require different interpretation and risk assessments depending on the patient's gender.

High-pitch coronary CTA limited to slower heart rates
Contrary to some previous studies, high-pitch, dual-source coronary CT angiography (CCTA) scans should be reserved for patients with the slowest heart rates, according to a new study published in the December issue of Radiology.

AHA: CT calcium scoring broadens heart attack risk prediction
CT-based calcium scoring is a strong predictor of heart attacks in the young and old, not just the typical middle-aged individual at intermediate risk, according to a study presented on Wednesday at the 2011 American Heart Association (AHA) meeting in Orlando, FL.

AHA: CCTA demonstrates low rate of downstream procedures
For as long as 2.5 years after undergoing coronary CT angiography (CCTA), invasive angiography and revascularization are uncommon, even in patients with significant coronary artery disease at CT, according to a report presented on Tuesday at the American Heart Association (AHA) meeting.

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.
