Patients show slight preference for MR colonography over colonoscopy

Most patients who underwent MR colonography (MRC) and optical colonoscopy preferred MRI, according to a new study by researchers from Essen, Germany, and Atlanta, GA. When the patients were questioned about which colorectal screening test they'd rather have in the future, however, MR's advantage dwindled.

VC measurements more accurate than optical colonoscopy

Virtual colonoscopy did a better job of measuring polyps than optical colonoscopy, and optimized 2D measurements were slightly more accurate than 3D, according to a just-published study from South Korea. The measurements affect not only thresholds for removal, but also polyp-matching algorithms in both modalities, explained the researchers from the Asan Medical Center and Seoul National University Hospital in Seoul.

CT enterography answers range of small-bowel questions

Some radiologists do their best to avoid CT enterography, but they're missing out on a wide range of diagnoses that alternative exams can't provide. Dr. Patrick Rogalla of Charité Hospital in Berlin offers advice for maximizing the value of CT enterography exams for indications ranging from tumor search to inflammatory bowel disease.

Translucency rendering aids prepless 3D VC

The use of primary 3D interpretation isn't generally recommended for reading reduced-prep virtual colonoscopy (VC) data. Reading is time-consuming, and 3D endoluminal views can make it difficult to distinguish from residual stool difficult. But a new study says that reading reduced-prep data in 3D is not only possible but accurate and time-efficient if a software translucency rendering tool is applied.

Study: VC is cost-effective in efficient exam settings

Even among patients at high risk of colorectal polyps and cancer, virtual colonoscopy can be a cost-effective way of finding lesions, according to a study from Denmark. The total costs of VC and conventional colonoscopy were comparable even when the conventional exam and polypectomy were performed on polyps 5-6 mm or larger, according to the researchers.

ED physicians can screen for AAA, study finds

By Erik L. Ridley

Emergency physicians are capable of handling ultrasound screening for abdominal aortic aneurysm (AAA), according to researchers from Yale University in New Haven, CT. The group studied the feasibility and cost-effectiveness of screening performed by emergency physicians on at-risk patients.

Contrast media add valuable information in US applications

By Erik L. Ridley

ATLANTIC CITY - Ultrasound contrast media is useful in many radiological applications and helps clinical practice, according to Dr. Yuko Kono of the University of California, San Diego (UCSD). She spoke Thursday during a session at this week's 2007 Leading Edge in Diagnostic Ultrasound conference.

Water enema may improve MDCT colon cancer staging

Although MRI is still the gold standard when it comes to colorectal cancer staging, a new study from Italy shows that preoperative multidetector-row CT (MDCT) staging using a water enema may offer some advantages over air insufflation. Water appears to improve the ability to assess local disease extent by slightly increasing the density difference between the colon wall and lumen.

Bill would boost funds for colorectal screening

After years of congressional cost-cutting, colorectal cancer screening could be in line for a booster shot. A bill introduced in the U.S. Senate (S. 1164) would restore full Medicare reimbursement for approved colorectal cancer screening exams such as colonoscopy and flexible sigmoidoscopy.

Screening model calls VC most cost-effective colon exam

Virtual colonoscopy is the cheapest and safest way to reduce colon cancer mortality among individuals 50 years and older, according to a new study. Using a minimum 6-mm polyp size threshold, VC was more than twice as cost-effective as optical colonoscopy per life year gained.
