An advanced visualization method for virtual colonoscopy could help computer-aided detection (CAD) programs slash false-positive rates, according to researchers from the State University of New York at Stony Brook and colleagues. Their study of asymptomatic screening patients reduced CAD false positives by nearly half, and could potentially render non-CAD VC image evaluation easier as well.

In what is believed to be a first in the U.S., radiologists at Lucile Packard Children's Hospital in Stanford, CA, have used prenatal MRI to detect a rare genetic disease in a newborn.

ST. LOUIS (Reuters Health), Mar 10 - The intensity of surveillance after curative-intent treatment for ovarian cancer is highly variable, according to a survey of gynecologic oncologists. Respondents were asked what they would advise each year for 10 years after initial treatment, including the number of x-rays, CTs, MRIs, and ultrasound exams.

The time is now to integrate medical images into electronic health records, for any hospitals planning healthcare IT upgrades to receive stimulus funds, a PACS implementation expert told attendees last week at the Healthcare Information and Management Systems Society annual meeting in Atlanta.

NEW YORK (Reuters Health), Mar 9 - New research suggests that the type of specialist a prostate cancer patient sees -- rather than the patient's own preference -- may determine the treatment he receives.

VIENNA - Compared with the U.S., the U.K. is perhaps not seen as a strongly litigious country, but a new analysis of clinical negligence claims in radiology presented at the European Congress of Radiology reveals a clear rise in recent years in the number and financial burden of malpractice suits.

VIENNA - Breast MRI computer-aided detection (CAD) technology can effectively distinguish between benign and malignant lesions, according to research from Germany presented at the 2010 European Congress of Radiology.

NEW YORK (Reuters Health), Mar 8 - Exercise testing is sensitive for coronary artery disease when ST-segment changes, angina, and hemodynamic variables are considered -- but it's still not as sensitive as CT angiography (CTA), a study from Denmark shows.

NEW YORK (Reuters Health), Mar 8 - In clinically localized prostate cancer, both radical prostatectomy and external beam radiotherapy inhibit metastatic progression, but prostatectomy seems more effective in high-risk patients, researchers report.

NEW YORK (Reuters Health), Mar 8 - Bedside ultrasonography allows acute cholecystitis to be confirmed or ruled out as effectively in the emergency department as in the radiology suite, new research shows.

VIENNA - A French study presented Sunday at the European Congress of Radiology found that nearly a third of mild contrast reactions actually are allergic in nature and might require referral to an allergist as soon as they become apparent.

VIENNA - A one-day bowel prep and virtual colonoscopy exam regimen offers sufficiently good image quality, making life easier for both patients and providers compared to a multiday regimen, according to a study presented Sunday at the European Congress of Radiology.

VIENNA - Although dose variations remain wide on the continent, there are opportunities for substantial improvement with dose-reduction training and programs, according to two European studies of clinical CT doses presented back-to-back Saturday at the European Congress of Radiology.
