Ultrasound elastography characterizes fibrosis severity
By Erik L. Ridley
A Spanish research team has found that ultrasound elastography can reliably differentiate between rapid or slow fibrosis in liver transplant patients, paving the way for earlier identification of patients at risk of hepatitis C recurrence.

Esophagrams not ideal for pediatric eosinophilic esophagitis
By Cynthia E. Keen
The number of cases of eosinophilic esophagitis, a chronic inflammatory disorder of the esophagus, is rising in pediatric populations. However, endoscopy and pathological testing should remain the primary means of diagnosing the disease, not esophagrams, according to radiologists at Cincinnati Children's Hospital Medical Center.

DAAS scale predicts necrotizing enterocolitis severity in infants
By Cynthia E. Keen
Duke University researchers have developed a 10-point Duke abdominal assessment scale (DAAS) that can simplify the review of multiple abdominal x-ray reports of infants with clinical symptoms of necrotizing enterocolitis, helping to predict the severity of the disease.

VC CAD aids experts in detecting intermediate polyps
By Eric Barnes
Computer-aided detection (CAD) can improve the performance of experienced radiologists in detecting intermediate-sized (6- to 9-mm) polyps, but it doesn't help find larger lesions, said researchers from Italy in results presented at the RSNA meeting earlier this month.

Lesion size and morphology at VC good predictors of histology
By Eric Barnes
Size and morphology are good predictors of whether a colorectal lesion harbors advanced histology and needs to be removed, according to a new multicenter study from Italy. The results suggest that polyps of the same size detected at virtual colonoscopy could be classified and managed differently based on their morphology.

CAD catches most flat polyps on virtual colonoscopy
By Eric Barnes
Computer-aided detection (CAD) is sensitive for all but the flattest of flat colorectal lesions, even in minimally prepped patients, according to a new study from Italy. Using CAD, radiologists significantly improved their ability to detect the elusive polyps, which can harbor precancerous lesions.

ASIR cuts dose in Crohn's disease patients
By Eric Barnes
CHICAGO - Low-dose abdominal CT images reconstructed with an adaptive statistical iterative reconstruction (ASIR) technique are equivalent -- and, in fact, slightly better in quality -- than standard-dose images reconstructed with filtered back projection.

By Edward Susman
CHICAGO - The child has lower right abdominal pain. A resident suspects appendicitis, but she wants to make sure ... Yep, there's an app for that. Researchers found that CT images sent via iPhone technology with $19.99 software are precise enough for correct diagnoses in 124 of 125 trials of the procedure.
