Iterative reconstruction techniques reduce radiation dose for pediatric brain CT

Summary:
Estimated radiation doses are substantially lower for pediatric CT exams of the brain that used an adaptive statistical iterative reconstruction technique (ASIR) compared to those that did not use ASIR.

A study conducted at Massachusetts General Hospital and Harvard Medical School found that estimated radiation doses are substantially lower for pediatric CT exams of the brain that used an adaptive statistical iterative reconstruction technique (ASIR) compared to those that did not use ASIR. The researchers found that the brain and salivary gland doses were much lower for ASIR-enabled exams compared to those without ASIR technique. However, no differences in the estimated organ doses were found for the thyroid gland, skeleton, and eye lenses across these two cohorts of CT exams.

"CT radiation dose is an important concern with all imaging sites, especially for children," said Ranish Deedar Ali Khawaja. "We performed this study to do a preliminary analysis of pediatric head CT examinations and to assess the factors influencing radiation doses."

Mean radiation dose was 1.6 1.5 mSv (estimated effective dose) in pediatric head CT. In addition to the iterative reconstruction algorithm, patient age and effective body diameter significantly affected the doses.

Dr. Khawaja and his fellow researchers will present the study on May 7 at the 2014 ARRS Annual Meeting in San Diego, CA.
