Insights
Amplitude coded colour Doppler sonography (aCDS) is effective in pediatric imaging, offering valuable diagnostic information in renal, abdominal, and oncological applications for infants and children.
Area of Science:
- Pediatric Radiology
- Medical Imaging
- Ultrasound Technology
Background:
- Conventional colour Doppler sonography (CDS) is a standard imaging technique.
- Amplitude coded colour Doppler sonography (aCDS) offers potential enhancements.
- Paediatric applications require specialized imaging approaches.
Purpose of the Study:
- To evaluate the utility and diagnostic performance of amplitude coded colour Doppler sonography (aCDS) in paediatric patients.
- To assess the accuracy and added diagnostic value of aCDS compared to conventional methods.
Main Methods:
- Analysis of 270 paediatric patients (newborn to 16 years) undergoing various aCDS applications.
- Correlation of aCDS findings with conventional CDS, clinical data, and other imaging modalities.
- Review and discussion of relevant scientific literature.
Main Results:
- aCDS demonstrated successful performance in 92.4% of paediatric investigations.
- Overall accuracy was 86.6%, with a sensitivity of 92% in successful investigations.
- aCDS provided additional diagnostic information in 18.6% to 48% of cases across different applications.
Conclusions:
- Amplitude coded colour Doppler sonography is a valuable and applicable tool for the majority of infants and children.
- aCDS enhances conventional paediatric ultrasound and colour Doppler sonography.
- Future integration with advanced modalities promises to expand sonographic diagnostic capabilities.
Objective:
The goal of this study was to evaluate the use of amplitude coded colour Doppler sonography (aCDS) in infants and children.
Methods:
We analysed our own experiences in 270 patients (mean age: 6.3 years, range: newborn--16 years) with various paediatric aCDS applications. The aCDS results of 460 individual investigations were correlated with conventional CDS results, clinical findings and the results of other imaging modalities. Additionally, relevant literature is reviewed and discussed.
Results:
ACDS is a valuable tool in paediatric sonography. It enriches the diagnostic field of ultrasound, particularly in regard to renal, abdominal, oncological and small part applications. ACDS could successfully be performed in 92.4% of investigations. Overall accuracy was 86.6% (in regard to the total number), sensitivity was 92% (calculated for the number of successful investigations), additional diagnostic information was gained in 18.6% to 48% of patients--depending on the field of application.
Conclusion:
ACDS is applicable to the majority of infants and children, in spite of the risk of motion artefacts. It is a valuable addition to conventional paediatric ultrasound and colour Doppler sonography. In conjunction with new modalities like three-dimensional sonography, harmonic imaging and ultrasound contrast agents it promises to continuously widen sonographic diagnostic potential.
