Imaging Studies for Cardiovascular System III: X-Ray

Imaging Studies for Cardiovascular System III: X-Ray

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
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...

Background:

Fluoroscopically-guided interventional (FGI) procedures can result in high patient and staff radiation doses.
Scatter radiation poses a significant occupational hazard for healthcare professionals in interventional settings.

Purpose of the Study:

To investigate the effectiveness of a region-of-interest (ROI) attenuator in reducing scatter dose to staff during FGI procedures.
To quantify scatter dose reduction across different anatomical regions (head, chest, abdomen) and staff positions.

Main Methods:

Utilized a 0.7 mm Copper ROI attenuator with a central circular hole (5.4 cm projected ROI).
Measurements were performed using a Kyoto anthropomorphic phantom and a 150-cc ionization chamber at various lateral distances (25 cm, 50 cm) from the gantry isocenter.
Scatter dose per entrance air kerma was measured with and without the ROI attenuator, varying beam energy and gantry angulation.

Main Results:

Scatter dose reduction ranged from 50%-65% for head imaging.
For chest and abdomen imaging, scatter dose reduction was 63%-72% at a 50 cm lateral distance.
Approximately 20% beam transmission was observed at 80 kVp with the ROI attenuator.

Conclusions:

An ROI attenuator composed of 0.7 mm Copper can significantly reduce scatter radiation exposure to staff in interventional radiology.
The ROI attenuator provides a practical method for dose reduction without compromising the full field of view imaging.
Implementing ROI attenuators is a viable strategy for enhancing radiation safety in FGI environments.
