X-ray tube modulation helps reduce pediatric CT dose
By Cynthia E. Keen
By modulating x-ray tube output based on patient characteristics, instead of using a fixed tube current, Texas researchers were able to lower radiation dose in pediatric CT studies by 23%, according to a poster presentation at this week's American Association of Physicists in Medicine meeting.

Database identifies radiation therapy toxicities in kids
By Cynthia E. Keen
Since 2004, radiation oncologists in Germany have been submitting information about pediatric radiotherapy treatments to a study trial center database. Now an analysis of acute toxicities from this database of more than 1,000 patients has been recently published in Radiotherapy & Oncology, providing an overview of the pattern of acute toxicities of irradiated organs.

Pediatric CTA aids congenital cardiac surgery planning
By AuntMinnie.com staff writers
From the perspective of a cardiac surgeon, the presurgical information gleaned from a CT angiography (CTA) exam of pediatric patients about to undergo surgery to repair congenital cardiac malformations is well worth the trade-off in radiation dose exposure. But just how useful is it?

MRI tops x-ray for ped ankle fractures
By AuntMinnie.com staff writers
Young children with isolated lateral ankle injuries are often diagnosed with Salter-Harris fractures of the distal fibula, even if x-ray examinations do not reveal a fracture. But an MRI scan may change the diagnosis to a sprain, according to specialists at Toronto's Hospital for Sick Children.

Point-of-care ultrasound useful for fracture diagnosis
By Cynthia E. Keen
Clinicians trained to use portable, point-of-care ultrasound equipment can achieve a high level of accuracy in identifying fractures in children and young adults when x-ray units are not available, according to a study published online in Injury.

Sedation costs add up for pediatric MRI studies
By Cynthia E. Keen
The costs of sedating or anesthetizing children for MRI exams can add up quickly. One Canadian hospital analyzed what it was spending on sedation and subsequently changed its workflow to improve efficiency, according to an article in the July issue of Radiology.

Court transcripts don't resolve questions in Mad River CT case
By Donna Domino
Despite the recent release of court transcripts from the Mad River CT overdose case, questions still remain as to how a Northern California radiologic technologist performed 151 CT scans on a 2-year-old boy in 68 minutes -- resulting in a massive radiation overdose.

FDG-PET/CT a good option for imaging pediatric osteosarcoma
By Wayne Forrest
PET/CT could be an option for evaluating children with osteosarcomas, but not for those with Ewing's or soft-tissue sarcoma due to lower levels of FDG uptake in these patients, a new study indicates. The findings differ from results in adults, which have shown similar FDG uptake levels among the sarcoma types.

Kids learn breathing technique for better chest CT exams
By Cynthia E. Keen
An ideal pediatric chest CT exam uses low radiation dose to acquire high-quality images devoid of respiratory motion artifacts. This is easier said than done for a variety of reasons, but pediatric radiologists at a children's hospital in Ohio have figured out how to do it -- and without sedation.

Shorter PET/CT acquisition times suitable for many kids
By Wayne Forrest
Pediatric PET/CT imaging times can be reduced by 30% for many patients without a loss of diagnostic utility, according to researchers from Seattle Children's Hospital and the University of Washington Medical Center in Seattle.
