Young adults face higher CT radiation risk than seniors
By Cynthia E. Keen
Age has a lot to do with the estimated radiation risk of developing cancer as a result of having an abdominal or pelvic CT scan. Senior citizens have half the risk of young adults, a research team told attendees at the American Roentgen Ray Society annual meeting being held in San Diego this week.

VC helps screen U.S. minorities
By AuntMinnie.com staff writers
Virtual colonoscopy is a useful colon screening exam in minority communities, particularly among individuals who might shy away from conventional colonoscopy, according to a poster study unveiled at the Digestive Disease Week meeting in New Orleans.

HDCT with ASIR recon sharpens low-dose abdominal images
By Eric Barnes
High-definition CT (HDCT) combined with adaptive statistical iterative reconstruction (ASIR) is a good way to diagnose abdominal conditions at very low radiation doses, according to researchers from Hong Kong.

CT perfusion distinguishes HCC from other liver lesions
By Eric Barnes
Radiologists in China are getting more traction out of their CT liver protocols with the use of perfusion dual-source CT (DSCT) exams, taking a bite out of MRI's traditional superiority in the process. DSCT is showing that it can often do a better job in differentially diagnosing hepatocellular carcinoma (HCC), liver metastases, and cavernous hemangioma in the clinical setting.

3T MRA protocol has value but falls short in abdominal vasculature
By Wayne Forrest
A time-resolved 3-tesla MR angiography (MRA) technique that uses less contrast dose than conventional high-resolution MRI has some advantages in the abdominal aorta, but its lower signal-to-noise ratio means it probably won't supplant conventional MRA, according to a study in the May Academic Radiology.

Small colon polyps on VC suggest presence of larger lesions
By Eric Barnes
Individuals with several diminutive colon polyps on virtual colonoscopy studies are far more likely than other screening subjects to also have a larger colorectal lesion, say researchers from the University of Munich in Germany.

Computer analysis bolsters liver elastography performance
By Erik L. Ridley
Computer-enhanced dynamic analysis of ultrasound elastography movies is a useful and reliable method for depicting liver hardness, yielding a high level of interreader agreement, according to research published April 14 in the World Journal of Gastroenterology.

Providers don't adequately discuss colon cancer screening
By Brian Casey
Healthcare providers aren't communicating adequately with patients regarding colorectal cancer screening, even though such discussions would improve screening rates, according to a new meta-analysis published in the April 13 issue of the Annals of Internal Medicine.

Hispanics have less access to colon screening
By Brian Casey
A study published online April 12 in Cancer indicates that Hispanics have less access to colon screening services, which may explain why Hispanics are less likely to undergo colon cancer screening than non-Hispanic whites.

Open-source software increases colon polyp conspicuity
By Eric Barnes
Visibility of colon polyps is increased and sensitivity improved with the use of threshold-based color-coding software in virtual colonoscopy, according to a new study from Italy. Even flat lesions were more often visible with use of the open-source 2D-based interpretation software.

Massive VC study yields trove of extracolonic cancers
By Eric Barnes
A study of more than 10,000 asymptomatic screening subjects found that more than one in 200 had unsuspected and typically large but mostly early-stage cancers detected outside the colon at virtual colonoscopy.
