Choice of Tube Extremity in Emission of Lowest Radiation Dose in Pediatric Patients

Not Applicable

Completed

• Conditions: Radiation Absorption; Radiography
• Interventions: Other: Thyroid facing the cathode end of xray machine; Other: Thyroid facing the anode end of xray machine

• Registration Number: NCT02925936
• Lead Sponsor: Instituto de Cardiologia do Rio Grande do Sul

Brief Summary

Compare the radiation in pediatric patients thyroid submitted to chest X-ray using the position of the anode and cathode.

Detailed Description

The study's primary goal was to compare radiation exposure in two different positions during chest x rays in children. It was conducted from June/2014 to July/2015, and included children from 0 to12 years old staying at the Pediatric Intensive Care Unit at the Instituto de Cardiologia de Porto Alegre, Brazil, with chest x ray requests during ICU stay. They were randomized to two groups: during the x ray, one group was positioned with the thyroid facing the anode end, and the other group was positioned with the thyroid facing the cathode end.
