U.S. children's hospitals reduce CT exam volume
By Cynthia E. Keen
Have efforts to raise awareness about pediatric radiation dose resulted in a lower volume of CT studies for children in the U.S.? That appears to be the case, according to an article published in the May issue of the American Journal of Roentgenology.

Thoracic CT finds PE in kids with cancer
By AuntMinnie.com staff writers
Routine contrast-enhanced thoracic CT exams identify unsuspected pulmonary emboli (PE) in nearly 2% of pediatric cancer patients, a prevalence level comparable to what is reported in adults.

Pediatric CT dose is low but varies widely in Belgium
By Cynthia E. Keen
A national survey of scan protocol behavior and radiation dose at hospitals in Belgium has found that even though most facilities are generally keeping pediatric CT radiation dose low, there is still some variation between sites in terms of median dose levels.

Imaging utilization can vary widely for pediatric inpatients
By Cynthia E. Keen
What factors influence the number of diagnostic imaging exams ordered for inpatients in children's hospitals in the U.S.? A statistical analysis of nearly 1.5 million pediatric inpatients conducted by researchers at Children's Hospital Boston generated more questions than answers.

Reduced dose can still yield acceptable pediatric CT images
By Wayne Forrest
By using simple weight-based kilovoltage adjustments with already low current, significant radiation dose reduction and acceptable image quality can be achieved for pediatric CT exams, according to a study in the May issue of the American Journal of Roentgenology.

Dual-phase CT protocol drops dose for tracheal exams in kids
By Cynthia E. Keen
Tracheomalacia, a weakness in the tracheal walls and supporting cartilage that can cause expiratory collapse, can be difficult to diagnose. Dual-phase CT provides a fast and accurate means of diagnosing the condition, but its use comes with an important caveat: double the radiation dose.

Role-playing helps rads convey news about fetal abnormalities
By Cynthia E. Keen
BOSTON - Advanced ultrasound and MRI procedures are making it easier for radiologists to identify fetal abnormalities. But telling a pregnant woman the news, often early in a pregnancy, is increasingly becoming the responsibility of pediatric radiologists, who are assuming roles as front-line physicians.

Skeletal PET gains support for pediatric bone scans
By Cynthia E. Keen
BOSTON - Skeletal scintigraphy with F-18 sodium fluoride is a safe and effective way to diagnose skeletal disorders in children and could be used instead of bone SPECT exams, according to research presented on Wednesday at the Society for Pediatric Radiology meeting.

Automated exposure control delivers uneven CT dose reduction
By Eric Barnes
Reducing tube current may be a popular way to lower CT radiation dose, but it's not necessarily an effective one. In a new study, medical physicists from Greece found that organ dose reductions resulting from tube current modulation with automated exposure control can vary -- especially in children.
