Prospective Comparison of Nine Different Handheld Ultrasound (HHUS) Devices by Ultrasound Experts with Regard to B-Scan Quality, Device Handling and Software in Abdominal Sonography

Diagnostics, 2024 · DOI: 10.3390/diagnostics14171913 · Published: August 30, 2024

Simple Explanation

This study compares nine different handheld ultrasound devices to see which ones work best for abdominal imaging. Experienced examiners tested each device on the same subjects. The study looked at B-scan quality (image clarity), how easy the devices are to handle, and the user-friendliness of the software. The examiners rated each device on a scale. The Vscan Air and SonoEye Chison were rated the highest overall. The B-scan quality varied considerably between the devices, which could affect their usefulness in clinical settings.

Study Duration

1 week

Participants

12 experienced examiners and healthy subjects

Evidence Level

Not specified

Key Findings

1
Vscan Air and SonoEye Chison achieved the best overall ratings, differing significantly from the other devices (p < 0.01).
2
Clarius C3HD3 and Vscan Air achieved the best results for B-mode quality.
3
D5CL Microvue achieved the best results for device handling.

Research Summary

This prospective study evaluates a large variety of HHUS devices in a comprehensive head-to-head comparison by several experts. The primary goal is to make a direct comparison of B-image quality, handling, and user-friendliness of the software for a total of nine different HHUS devices in clinical abdominal US. The findings of this study can assist in the selection of an appropriate HHUS device for specific applications, considering the clinical objectives and acknowledging the inherent limitations.

Practical Implications

Device Selection

The findings assist clinicians in selecting the most suitable HHUS device based on their specific clinical needs and priorities, considering factors like image quality, handling, and software.

Training

The study provides insights for ultrasound training programs, emphasizing the importance of familiarizing users with different devices and their specific features to optimize clinical performance.

Future Development

Identified discrepancies in B-scan quality and other features can guide manufacturers in improving future HHUS device designs, focusing on enhancing image resolution and usability.

Study Limitations

1
Not all available devices could be included.
2
The sample of examiners was very small.
3
Other factors, such as pricing, durability, heat development during prolonged use, and more, were not evaluated.
