A new computer-aided detection (CAD) algorithm automatically labels abdominal arteries extracted from CT images. The work-in-progress system is more accurate and less dependent on error-prone features than previous CAD schemes, say researchers from Nagoya, Japan.

NEW YORK (Reuters Health), Sep 2 - Women scheduled for gynecologic surgery are very likely to undergo unnecessary tests before their operation, a new study shows. While the tests aren't harmful, they may be anxiety-producing and they certainly are costly, according to the researchers.

With the help of 1.5-tesla cardiac MRI, German researchers have found that the human heart adapts to triathlon training by developing greater muscle mass and wall thickness, as well as larger left atria and larger right and left ventricles, according to a study to be published in the October issue of Radiology.

Contrast-enhanced MRI dynamic evaluation of the bowel wall can effectively visualize inflammation caused by celiac disease, aiding the assessment of patients with this condition, according to a study in the September issue of Radiology.

CHICAGO (Reuters), Sep 1 - Women with mutations in the well-known BRCA1 or BRCA2 genes who have their breasts and ovaries removed are much more likely to survive than women who do not get preventive surgery, U.S. researchers said on Tuesday.

NEW YORK (Reuters Health), Sep 1 - Hormone replacement therapy after menopause may interfere with the accuracy of mammograms used to screen for breast cancer -- and the risk may be greater with hormones delivered by patch or injection compared with pills, a new study finds.

A California bill that would implement new procedures and reporting requirements to protect patients from medical radiation overdoses passed a procedural vote in the state Senate on August 30 and has been sent to Gov. Arnold Schwarzenegger for his signature.

Offering radiologists financial incentive to sign their reports quickly improves turnaround times, according to a study conducted by Massachusetts General Hospital researchers and published in the September issue of the American Journal of Roentgenology.

MRI exams can provide valuable information about neurological abnormalities in preterm infants. But the process of having an MRI exam can be hazardous to very fragile and unstable neonates, limiting the value of this powerful technology -- unless you have an MRI-compatible incubator.

Procedure volume for radiography/fluoroscopy (R/F) systems in the U.S. has declined over the past five years, most likely due to increased use of CT for procedures once reserved for R/F, according to a new report released this week by market research firm IMV Medical Information Division.

While adoption of electronic health records technology may be the mantra of hospital executives throughout the U.S., the reality is that only 2% meet the "meaningful use" criteria established by the U.S. Centers for Medicare and Medicaid Services, according to a new report in Health Affairs.

Iterative reconstruction techniques for CT were once limited to dose reduction. But a new generation of iterative reconstruction algorithms is focused on image quality, processing data more rapidly and delivering more-natural looking images as well.

NEW YORK (Reuters Health), Aug 28 - Clinical misdiagnoses very seldom lead to enucleation and such outcomes have decreased over the last half century, researchers report in the August Archives of Ophthalmology. And the misdiagnosis rate has also decreased steadily, thanks to improvements in diagnostic imaging.
