Summary
Paediatric chest X-ray doses varied significantly across Bulgarian hospitals due to inconsistent practice. Recommendations focus on optimizing techniques to reduce patient radiation exposure and improve diagnostic imaging quality.
Area of Science:
- Radiological Sciences
- Medical Physics
- Paediatric Imaging
Background:
- Paediatric radiography requires specific protocols to minimize radiation exposure.
- Variations in practice can lead to suboptimal patient doses.
- Ensuring radiation safety in paediatric X-ray examinations is crucial.
Purpose of the Study:
- To compare paediatric radiological practices and patient doses in Bulgarian hospitals.
- To identify areas for improvement in chest X-ray examinations for children.
- To assess the impact of practice variations on radiation exposure.
Main Methods:
- Data collection from 163 paediatric patients across three hospitals.
- Standardized data recording using a dedicated form.
- Calculation of Entrance Surface Air Kerma (ESAK) from Air-Kerma Area Product (KAP) and field size.
Main Results:
- Significant variations observed in KAP and ESAK values.
- Frequent use of inappropriate film sizes and inadequate collimation.
- Suboptimal utilization of automatic exposure control and antiscatter grids.
- Lack of organ shielding and proper collimation for dose reduction.
Conclusions:
- Paediatric chest radiography practices in Bulgaria exhibit considerable variability.
- Inconsistent application of radiation protection principles leads to unnecessary patient doses.
- Implementing standardized protocols and training is recommended to optimize paediatric X-ray procedures.

01:30Radiological Investigation I: X-ray and CT
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and the...
01:20Imaging 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...

01:24X-ray Imaging
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...
01:13Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
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...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
