Insights
A new sensor designed to improve chest X-ray imaging in children did not significantly increase the rate of images taken during inspiration. While not improving inspiration phase acquisition, the device showed potential for future automated chest radiography applications.
Area of Science:
- Pediatric Radiology
- Medical Imaging Technology
Background:
- Accurate interpretation of chest radiographs requires images acquired at peak inspiration.
- Obtaining inspiratory phase images is challenging in young children who cannot hold their breath on command.
Purpose of the Study:
- To evaluate if a novel breathing movement sensor could increase the proportion of chest radiographs obtained during the inspiration phase in infants and young children.
- To assess the feasibility of using the sensor for quality chest radiography in pediatric patients.
Main Methods:
- A randomized controlled study was conducted with 124 infants and children under 3 years old.
- Participants were allocated to either a with-sensor or without-sensor group.
- Chest radiographs were analyzed to determine if they were taken during the inspiration phase.
Main Results:
- Overall, 81% of all chest radiographs were obtained during inspiration.
- There was no statistically significant difference in the proportion of inspiratory phase images between the with-sensor group (82%) and the without-sensor group (81%).
- Radiologic technologists could maintain image quality using the sensor without direct observation of chest movement.
Conclusions:
- The developed sensor did not improve the acquisition of chest radiographs during the inspiration phase in the studied pediatric population.
- Despite the null result, the sensor shows promise for future applications in automating chest radiography procedures.
- Further research is warranted to explore the sensor's potential in optimizing pediatric imaging workflows.
Abstract:
Chest radiographs should be obtained at the peak of inspiration so that radiological findings can be precisely interpreted. However, this is not easily achieved, particularly in young children who do not follow the instruction to hold their breath. We developed a sensor that detects the breathing movements and conducted a randomized controlled study to determine whether the sensor would increase the proportion of chest radiographs obtained in the inspiration phase. We recruited 124 infants and children aged less than 3 years, who visited the pediatric department of a general hospital in Tokyo, Japan, and allocated them into one of two groups: with-sensor and without-sensor groups. Overall, 81% of all images were obtained during inspiration. The proportion of chest radiographs taken during inspiration was not statistically different between the two groups (81% vs. 82%). In the with-sensor group, radiologic technologists were able to obtain chest radiographs of the same quality while not observing the chest movement, but the sensor. The use of the sensor did not increase the proportion of chest radiographs taken in the inspiration phase in this study. However, this null result may indicate the possibility of utilizing the sensor for automatizing chest radiography in the future.

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
