Laser targeting with C-arm fluoroscopy: effect on radiation exposure for pediatric patients.

The primary purpose of obtaining laser targeting devices for C-arm fluoroscopy was to attempt to reduce radiation to the pediatric population in Connecticut Children's Medical Center's commitment to Imaging Gently. Fluoroscopy times for placing central lines in the operating rooms were documented for two months prior to the installation of the lasers and then for twenty procedures after installation and training on the devices. Fluoroscopy times trended down 25% calculated by a simple mean and standard deviation.

Location of the ovaries in girls from newborn to 18 years of age: reconsidering ovarian shielding.

Background: Guidelines for ovarian shielding are to place a lead shield in the midline of the abdomen at the level of the umbilicus. However, the ovaries are routinely seen at other locations on all types of imaging examinations.

Objective: To determine the position of the ovaries in girls, newborn to 18 years of age, in order to assess efficacy of ovarian shield placement.
