Pediatric 64-MDCT coronary angiography with ECG-modulated tube current: radiation dose and cancer risk.

Abstract

OBJECTIVE The purpose of our study was to measure the radiation dose from ECG-gated CT coronary angiography in children and to estimate the cancer risk associated with the radiation dose. MATERIALS AND METHODS Organ doses were measured with a 5-year-old pediatric phantom and thermoluminescent dosimeters on a 64-MDCT scanner. Four retrospectively ECG-gated… (More)
