Slice thickness, reading method don't change VC results

By Eric Barnes

Neither the primary reading method (2D versus 3D) nor reconstruction slice thickness affected VC results in significant ways in a recent study by researchers from the Mayo Clinic in Rochester, MN. The group also found that the novel "virtual dissection" viewing method saved reading time.

Advanced liver imaging shapes surgical strategies

By Eric Barnes

The days of planning liver interventions on the strength of a few CT or MR reconstructions may be numbered. Researchers from Germany and beyond are honing a set of advanced planning tools that not only provide high-resolution color-coded 3D visualization of the liver parenchyma and vasculature, but offer quantitative views of the intrahepatic vessel branching system and the risks of cutting at a given point in the organ.

Study: Primary 3D VC equivalent to colonoscopy

By Eric Barnes

A British study of symptomatic patients undergoing same-day virtual and conventional colonoscopy found the two methods equivalent for the detection of clinically significant polyps. In fact, the segmentally unblinded results showed that virtual colonoscopy did slightly better than optical colonoscopy for the detection of clinically significant polyps 6 mm and larger.

'Filet view' VC software pares reading time

By Eric Barnes

The latest version of a novel 3D virtual colonoscopy viewing method significantly shortened reading times compared to 2D in a new study, though sensitivity was unchanged from conventional methods, researchers from South Korea reported.

Atlas of Gastrointestinal Imaging, Chapter 5 -- The Colon and Rectum

By Dr. Perry Pickhardt

Imaging evaluation of the large intestine has undergone remarkable advances over the past decade, particularly with the advent of CT colonography (CTC, also referred to as virtual colonoscopy). Optical colonoscopy (also referred to as conventional or invasive colonoscopy) and CTC allow for complementary diagnostic evaluation of the colonic mucosa.

Whites prefer virtual colonoscopy; minorities like conventional

By Eric Barnes

Blacks and other racial and ethnic minorities, who are already screened for colorectal cancer (CRC) in lower numbers and suffer its consequences more acutely than the U.S. population as a whole, don't seem too impressed with virtual colonoscopy, according to a new study by researchers from New York City.

MDCT's 'virtual Whipple' offers practice run before complex surgery

By Eric Barnes

Among the nearly 30,000 cases of pancreatic cancer diagnosed each year in the U.S., an estimated 5% to 30% have tumors that are contained entirely within the head of the pancreas. This relatively fortunate subgroup has a better chance of surviving long term via the Whipple procedure. Radiologists at Beth Israel Deaconess Medical Center in Boston are hoping to boost the odds of surgical success with the virtual Whipple, a CT-based planning tool they've developed to give surgeons an idea of what they're going to find step-by-step during the Whipple procedure.
