Summary
Amplitude coded-colour Doppler sonography (ACDS) effectively visualizes pediatric kidney perfusion changes. This advanced technique improves detection of focal and diffuse abnormalities compared to standard color Doppler, aiding diagnosis in children with renal disease.
Area of Science:
- Medical Imaging
- Pediatric Nephrology
- Diagnostic Ultrasound
Background:
- Assessing renal perfusion is crucial for diagnosing pediatric kidney diseases.
- Conventional color Doppler sonography (CDS) has limitations in visualizing subtle perfusion changes.
- Amplitude coded-colour Doppler sonography (ACDS) offers potential for enhanced visualization.
Purpose of the Study:
- To evaluate the efficacy of amplitude coded-colour Doppler sonography (ACDS) in depicting altered renal perfusion in pediatric patients.
- To compare ACDS performance against conventional CDS, scintigraphy, CT, and clinical findings.
- To determine the diagnostic value of ACDS in a spectrum of pediatric renal conditions.
Main Methods:
- Prospective study involving 180 renal units (90 pediatric patients) with various renal diseases.
- Simultaneous examinations using conventional color Doppler sonography (CDS) and amplitude coded-colour Doppler sonography (ACDS).
- Comparison of ACDS results with scintigraphy, CT, and clinical data for validation.
Main Results:
- ACDS demonstrated normal vasculature in 96% of healthy kidneys.
- ACDS accurately depicted focally impaired perfusion in 89.7% of affected kidneys.
- ACDS showed an 87.1% overall agreement with gold standards for both focal and diffuse perfusion abnormalities.
Conclusions:
- Amplitude coded-colour Doppler sonography (ACDS) is a valuable tool for assessing pediatric renal perfusion.
- ACDS improves visualization of perfusion deficits, particularly focal ones, over standard CDS.
- ACDS should be considered an important adjunct in the diagnostic workup of pediatric renal diseases.
