DSCT compares full- to half-dose VC by patient October 8, 2012 -- Mayo Clinic researchers used iterative reconstruction to acquire half-dose virtual colonoscopy exams with dual-source CT (DSCT) and compare them to full-dose exams without scanning patients twice. The technique offers a more accurate way to compare dose levels between different CT protocols, according to a new study in the Journal of Computer Assisted Tomography.

2 technologists read VC studies as well as 1 radiologist September 5, 2012 -- When it comes to reading virtual colonoscopy studies, a radiologic technologist is no match for a trained radiologist. But two technologists are another matter entirely: They were equivalent to, and maybe slightly better than, a single radiologist, according to a new study in Radiology.
Modular training software teaches techs the art of VC August 7, 2012 -- A new software-based training tool from the University of Chicago promises to train CT technologists in the complex procedure of virtual colonoscopy -- minus the image interpretation. The tool could help meet training needs should virtual colonoscopy come into widespread use for colorectal cancer screening.
Japanese team finds more flat polyps with virtual colonoscopy August 1, 2012 -- Flat colorectal lesions aren't easy to detect at virtual colonoscopy. But a group from Japan did quite well finding them after patients underwent bowel cleansing and automated insufflation before CT scanning, according to a new study in Acta Radiologica.
ACR, CCA urge Congress to approve VC payment bill July 18, 2012 -- Encouraged by a new study confirming virtual colonoscopy's utility in seniors, the American College of Radiology (ACR) has joined with screening advocacy group Colon Cancer Alliance (CCA) to urge the U.S. Congress to pass a bill that would require Medicare payment for screening.
VC again found effective in Medicare population June 29, 2012 -- A study of more than 1,400 individuals screened with virtual colonoscopy found that the technique is effective in patients 65 years and older, researchers report in the July issue of the American Journal of Roentgenology.
Uninsured women less likely to get cancer screening June 18, 2012 -- NEW YORK (Reuters Health) - People without health insurance in rural areas are less likely to be up-to-date for routine health checkups and cancer screening than those with coverage, according to a new study.
Repeat VC after 5 years shows few advanced lesions June 13, 2012 -- Individuals who were negative in their first round of virtual colonoscopy screening tend to stay that way at repeat screening five years later. The results are a positive sign that VC is a good way to detect significant lesions before they can advance to malignancies.
DDW: Patients prefer conventional colonoscopy versus VC May 22, 2012 -- Gastroenterologists from British Columbia were surprised to find that patients undergoing same-day virtual colonoscopy followed by conventional colonoscopy preferred the latter, according to a presentation on Sunday at the Digestive Disease Week (DDW) meeting in San Diego.
Sigmoidoscopy an option for colon cancer screening May 21, 2012 -- NEW YORK (Reuters Health) - Screening for colon cancer using a flexible tube -- which is less invasive and more convenient than colonoscopy -- may also help prevent new cases and deaths from the disease, a new study suggests.
