New Technology Reduces Radiation


Children's Hospital offers new computed tomography (CT) technology that cuts patients' radiation exposure by half.  Children's 64-slice CT scanner with the new adaptive statistical iterative reconstruction (ASIR) software-based technology delivers high-speed, high-quality images with 25 percent to 50 percent less radiation. The decrease is based on the type of procedure the child undergoes. The Hospital’s 16-slice CT scanner already utilizes the dose-reduction software.

CT Scanner displayed“This technology enables us to significantly reduce radiation levels on our fastest CT scanner and administer just the dose required to achieve quality images,” said Elsa Ozuna-Richards, director, diagnostic imaging services, Children’s Hospital. “This is especially important for our kids who may need multiple imaging tests, such as cancer patients.”

Mindful that growing children are considerably more sensitive to radiation than adults, Children’s Hospital has long been committed to ensuring pediatric imaging services with minimal radiation. With CT, 1.5T and 3T MRI capabilities, as well as the latest cardiac and ultrasound technology, Children’s is well-equipped to meet the high demand for diagnostic imaging services across the Valley. Sedation services are also available for young patients to make them more comfortable during the procedure.  

“Concern about radiation should not be a barrier for children who need these tests to receive the best medical care,” said Ozuna-Richards.

Areeje Hamza, whose 9-year-old son, Adham Hamza, has had both CT and MRI scans for various medical reasons throughout his treatment for a brain tumor since he was a baby, was pleased to hear about the new CT technology. Children with cancer like Adham require regular scans to monitor their progress. "Adham undergoes one scan every two months at Children’s Hospital, and the fact that it is possible for kids who receive CT to avoid radiation is very reassuring," said Hamza. "I believe that getting access to more advanced technology will make parents feel that here's a hospital that is investing in my child's safety and wellbeing."
