Importance Increased use of computed tomography (CT) in pediatrics raises concerns about
cancer risk from exposure to ionizing radiation. Objectives To quantify trends in the use of …

Background Although CT scans are very useful clinically, potential cancer risks exist from
associated ionising radiation, in particular for children who are more radiosensitive than …

Context Use of diagnostic imaging has increased significantly within fee-for-service models
of care. Little is known about patterns of imaging among members of integrated health care …

We developed computational methods and tools to assess organ doses for pediatric and
adult patients undergoing computed tomography (CT) examinations. We used the …

The central dose quantities used in radiological protection are absorbed dose, equivalent
dose, and effective dose. The concept of effective dose was developed by the International …

This paper describes the development and testing of VirtualDose—a software for reporting
organ doses for adult and pediatric patients who undergo x-ray computed tomography (CT) …

Purpose: To establish an organ dose database for pediatric and adolescent reference
individuals undergoing computed tomography (CT) examinations by using Monte Carlo …

Computed tomography (CT) is the single biggest ionising radiation risk from anthropogenic
exposure. Reducing unnecessary carcinogenic risks from this source requires the …

Purpose With the rising number of computed tomography (CT) examinations and the trend
toward personalized medicine, patient‐specific dose estimates are becoming more and …

Purpose: To investigate the correlation of size‐specific dose estimate (SSDE) with absorbed
organ dose, and to develop a simple methodology for estimating patient organ dose in a …
