NEW YORK (Reuters Health), Mar 2 - A new battery-operated compression device is at least as effective as low-molecular weight heparin in preventing venous thromboembolism (VTE) after hip arthroplasty, but with a lower risk of major bleeding, new research suggests.  

A new study published in this month's issue of Journal of Children's Orthopaedics indicates that breech babies at risk of hip dysplasia might benefit from an extra imaging exam beyond what's recommended by current clinical guidelines.  

Computer-aided detection (CAD) technology in radiology has largely focused on cancer applications in the breast, chest, and colon. But with the pace of innovation slowing in those fields, the development of new musculoskeletal CAD applications could help revitalize the technology.  

Researchers from France have found that whole-body dynamic contrast-enhanced MRI can help assess treatment response in patients receiving stem cell therapy for multiple myeloma by providing quantitative analysis of bone marrow and focal lesion enhancement.  

Researchers from a Tennessee children's hospital have found that thallium-based bone nuclear imaging studies can raise the risk of cancer incidence in pediatric patients, according to an article in the January issue of the American Journal of Roentgenology.  

When a CT exam is ordered for a child presenting with cervical spine trauma, follow-up radiography adds little to no additional diagnostic information, according to an analysis from the Hospital for Sick Children in Toronto published in the February issue of the American Journal of Roentgenology.  

Postmenopausal women who are older and thinner are more susceptible to developing pelvic fractures following radiation therapy (RT) for cervical cancer than younger, premenopausal women with larger body mass indexes, if patients treated at M. D. Anderson Cancer Center over a six-year span are representative.  

Results from a new clinical study indicate that 3-tesla MRI is as effective as MR arthrography in detecting acetabular labral tears in the hip, saving patients an unnecessary procedure and potential complications from an arthrogram.  

Ohio researchers have developed a program to semiautomatically process knee MR images with the same -- and, in some cases, better -- accuracy as radiologists in one-fourth the time. The software is designed to segment the meniscus to compare normal knees with knees from patients with moderate osteoarthritis.  

Dr. Gia Deangelis is a University of Virginia radiologist who was supposed to be in Port-au-Prince the day the quake struck. She is now working in a rural clinic in Grison-Garde, north of the decimated capital of Port-au-Prince. Here are her observations.  

When an infant or toddler is diagnosed with a bone fracture, is the injury the result of an accident, child abuse, or an old disease such as rickets making a comeback in modern society? Radiography can help radiologists make the distinction.  

A stand-up MRI scanner found signs of lumbar spine compression in children carrying full backpacks, according to researchers from the University of California, San Diego School of Medicine.  

An American College of Radiology Imaging Network (ACRIN) study has determined that image-guided radiofrequency (RF) ablation is safe and effective for lowering the level of pain experienced by cancer patients with bone metastases.  

A new quantitative CT (QCT) technique offers hope that osteoporosis scans could someday be performed passively -- and automatically -- from abdominal CT scans acquired for other clinical purposes, according to researchers from the U.S. National Institutes of Health in Bethesda, MD.  

Epiphyseal cartilage perfusion abnormalities are more common among children with osteomyelitis and septic arthritis, and examining the characteristics of these abnormalities could help in diagnosing the conditions, according to research from Children's Hospital at Vanderbilt.  

NEW YORK (Reuters), Dec 11 - Women who took a commonly-used class of osteoporosis drugs called bisphosphonates had significantly fewer invasive breast cancers than women not using the bone-strengthening pills, according to a new analysis of data from the Women's Health Initiative.
