320-row CT minimizes dose in pediatric abdominal studies
By Eric Barnes
It's no secret that CT radiation dose levels in children -- especially in the emergency department, where patients are fidgety and physicians need fast answers -- are too high. One solution, investigated by researchers from Toronto and Berlin, is wide-area-detector scans with 320-detector-row CT.

MRI enterography shows shortcomings for Crohn's disease
By Wayne Forrest
Although MRI enterography can diagnose important incidental findings in a minority of patients with suspected or known Crohn's disease, Dutch researchers have concluded that a substantial number of patients experience unnecessary morbidity because of additional examinations of benign or normal conditions.

MSK applications could give CAD a shot in the arm
By Erik L. Ridley
Computer-aided detection (CAD) technology in radiology has largely focused on cancer applications in the breast, chest, and colon. But with the pace of innovation slowing in those fields, the development of new musculoskeletal CAD applications could help revitalize the technology.

320-row perfusion CT shows promise for pancreatic tumors
By Eric Barnes
Perfusion CT with a 320-detector-row scanner offers improved resolution of pancreatic tumors due to its ability to image the entire organ without slice overlap, according to researchers from Berlin and Toronto.

New VC CAD algorithm reveals submucosal colon cancers
By Eric Barnes
A new computer-aided detection (CAD) algorithm goes beyond flat-polyp detection to find submucosally invading colorectal cancers with virtual colonoscopy. Researchers say the software offers an important alternative to traditional CAD feature classification that could improve the sensitivity of all VC studies.

Preoperative CT may reduce negative appendectomies in women
By Eric Barnes
A 10-year review of more than 1,000 patients at a North Carolina hospital found that preoperative CT scans may reduce unnecessary surgeries in women of reproductive age with suspected acute appendicitis, according to an article published in the February issue of Radiology.

Colon stenting no barrier to virtual colonoscopy
By Eric Barnes
Flexible metallic stenting of the colon is common in patients treated for occlusive colorectal cancers. But conventional colonoscopy isn't a good way to follow up on these patients postoperatively, say Korean researchers.

Experience counts when reading contrast ultrasound liver images
By Erik L. Ridley
Radiologists with experience reading contrast-enhanced ultrasound images have the upper hand over neophytes in characterizing malignant liver tumors, according to research published in the January issue of the Journal of Ultrasound in Medicine.

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.

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.

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.

Liver metastases more conspicuous at low-energy DSCT
By Eric Barnes
CHICAGO - Hypovascular liver lesions are better visualized at lower photon energies in dual-source CT (DSCT), say researchers from New York City.
