VC CAD plus 3D improves sensitivity for novice readers
By Eric Barnes
Computer-aided detection (CAD) with 3D viewing improves sensitivity for polyp detection among less experienced readers, and may also speed up reading times and reduce false-positive detections. On the other hand, the performance of experienced readers did not improve significantly with CAD use, researchers from the University of Rome concluded.

VC CAD plus electronic cleaning boosts sensitivity, false positives
By Eric Barnes
Computer-aided detection (CAD) of colorectal polyps combined with electronic cleansing of tagged data is a promising but technically daunting approach to finding more polyps in virtual colonoscopy. In a new Korean study, electronic cleansing slightly increased the sensitivity of CAD but more than doubled the number of false-positive detections.

HIV case probed in tainted colonoscope investigation
By AuntMinnie.com staff writers
The U.S. Department of Veterans Affairs is investigating whether there's a link between a patient's positive HIV test and unsterilized colonoscopy equipment that may have exposed thousands of veterans to infectious diseases.

Adding chest CT to VC not cost-effective, study finds
By Eric Barnes
Adding a chest CT scan to screening virtual colonoscopy isn't cost-effective in a cohort of average-risk patients, a new model-based analysis concluded. Although the additional anatomic coverage increased the clinical efficiency of CT-based screening, the combined test would not detect enough serious pathology to cover the costs of detection and follow-up of disease.

Virtual colonoscopy CAD finds most cancers
By Eric Barnes
A computer-aided detection (CAD) algorithm designed to find polypoid lesions of the colon also does fairly well at finding frank cancers, researchers from the U.K. concluded. But sensitivity varies depending on the system settings and the quality of the prep.

Half of states now offer private-payor VC coverage
By AuntMinnie.com staff writers
The U.S. Centers for Medicare and Medicaid Services may be on the verge of denying coverage for virtual colonoscopy, but private payors are rushing to cover the virtual exam in unprecedented numbers.

Pressure builds on CMS to pay for VC
By AuntMinnie.com staff writers
Members of Congress and lobbyists are putting pressure on the U.S Centers for Medicare and Medicaid Services (CMS) to reverse its opposition to federal reimbursement for virtual colonoscopy.

Digital tomo works well for some kidney, ureteral stones
By Brian Casey
A new study by Belgian researchers indicates that digital tomosynthesis could be useful for assessing ureteral and kidney stones, particularly for screening patients prior to CT. But the digital radiography technique has different levels of accuracy depending on the location and size of stones.

Automated CT volumetry of lymph nodes gauges treatment response
By Eric Barnes
Cancer patients who respond to neoadjuvant therapy have a better prognosis than nonresponders, of course, but with the exception of FDG-PET, reductions in the size of tumors treated with chemotherapy or radiation have been difficult to gauge using imaging modalities that are capable of delineating the anatomy.

VC/AAA screening combo cost-effective in older adults
By Eric Barnes
A new analytic model has found that virtual colonoscopy is a highly cost-effective colon cancer screening method for older adults in the Medicare population, especially when combined with screening for abdominal aortic aneurysm (AAA), a test performed using the same CT dataset at little additional cost.

Dirty colonoscopes spark inquiry at VA hospitals
By AuntMinnie.com staff writers
Colonoscopes that were rinsed but not disinfected before being reused have exposed thousands of patients treated at Veterans Affairs (VA) hospitals to hepatitis, HIV, and other diseases, leading to calls for an inspector general's inquiry into the matter.
