X-ray Dose Reduction through Adaptive Exposure in Fluoroscopic Imaging
Published on: September 11, 2011
Decreasing radiation exposure on pediatric portable chest radiographs
Purpose:
To determine whether additional shielding designed for pediatric patients during portable chest exams that ascertain endotracheal tube placement would significantly decrease the amount of scatter radiation.
Methods:
Children aged 24 months or younger were intubated and received daily morning chest radiographs to determine endotracheal tube placement.
Results:
For each measurement, the amount of scatter radiation decreased by more than 20% from a nonshielded exposure to a shielded exposure.
Discussion:
There was a significant decrease in scatter radiation when using the lead shielding device along with appropriate collimation vs appropriate collimation alone.
Conclusion:
These results suggest that applying additional shielding to appropriately collimated chest radiographs could significantly reduce scatter radiation and therefore the overall dose to young children.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
