Insurance coverage and doctor visits boost colon screening rates
By Eric Barnes
A new study of more than 20,000 screening-age individuals in Texas found that health insurance coverage and regular doctor visits were the main drivers of colorectal cancer screening, which remained dismally low overall in a community-based healthcare system.

ACR to create LI-RADS lexicon
By AuntMinnie.com staff writers
The American College of Radiology (ACR) has convened a LI-RADS (Liver Imaging Reporting and Data System) committee to develop a system for standardized reporting and data collection for CT and MRI surveillance for hepatocellular carcinoma.

Ultrasound tops scintigraphy in gallbladder function evaluation
By Erik L. Ridley
Sonography is cheaper, more reproducible, and faster than scintigraphy for evaluating gallbladder function using sincalide cholecystokinin, according to research published in the September issue of the Journal of Ultrasound in Medicine.

Advanced image processing stitches together CE images
By Eric Barnes
An image processing technique forged in Japan could make wireless capsule endoscopy (CE) more useful by analyzing and cobbling together the somewhat unpredictable sequence of small intestine images generated by the tiny capsule endoscopy cameras.

Most choose VC over colonoscopy, study shows
By Eric Barnes
A new study from the Netherlands has found that most patients preferred reduced-prep virtual colonoscopy over conventional optical colonoscopy. Patients judged reduced-prep VC, both prep and procedure, as less burdensome, a fact the researchers hope could lead to greater compliance in colorectal cancer screening.

Contrast US beats MRI, CT for liver lesions
By AuntMinnie.com staff writers
Contrast-enhanced ultrasound is more accurate than MRI and CT for characterizing focal liver lesions, according to a new study.

Wider field-of-view speeds 3D virtual colonoscopy
By Eric Barnes
Virtual colonoscopy is not only faster, it's just as accurate when readers increase the field-of-view and perform a single fly through rather than two for each view (prone and supine), say researchers from the University of Wisconsin in Madison.

Childhood cancer survivors susceptible to diabetes
By AuntMinnie.com staff writers
Individuals who received total body or abdominal radiation therapy as treatment for childhood cancer have an increased risk of becoming diabetic when they reach adulthood, according to a new study.

Sophisticated electronic bowel cleansing boosts polyp detection
By Eric Barnes
A new suite of investigational image-processing tools known as structure-analysis cleansing is improving the results of virtual colonoscopy scans performed after limited bowel preparation. The goal is to make virtual colonoscopy easier on patients and persuade them to get screened for colorectal cancer.

Topographical height mapping moves mountains in polyp detection
By Eric Barnes
A little geography goes a long way in computer-aided detection of virtual colonoscopy. Researchers from the National Institutes of Health and Old Dominion University have found a novel way to use topographical height mapping for polyp detection and measurement.

Measuring lean body weight can optimize CT contrast dose
By Eric Barnes
Researchers at Duke University report that radiologists can minimize contrast dose and optimize enhancement of focal lesions by basing their contrast administration protocols on patients' lean body weight, rather than on total weight.

Virtual gastroscopy distinguishes benign from malignant ulcers
By Eric Barnes
Three-dimensional CT imaging of the stomach has improved to the point where it's just as useful as endoscopy for differentiating benign from malignant gastric ulcers, albeit with important differences, say researchers from Taiwan.
