Insights
This study establishes normal liver, spleen, and kidney dimensions in children. Body height is the best predictor for organ size, crucial for diagnosing pediatric conditions.
Area of Science:
- Pediatric imaging
- Diagnostic sonography
- Human anatomy
Background:
- Accurate organ size assessment is vital for pediatric health.
- Normal dimension ranges for pediatric liver, spleen, and kidney are essential for clinical practice.
Purpose of the Study:
- To establish normative sonographic dimensions for the liver, spleen, and kidney in healthy children.
- To identify key anthropometric factors correlating with these organ dimensions.
Main Methods:
- Prospective sonographic evaluation of 307 pediatric subjects (5 days to 16 years).
- Measurement of at least two dimensions for liver, spleen, and kidney.
- Correlation analysis with sex, age, body weight, height, and body surface area.
Main Results:
- No statistically significant sex-based differences in organ dimensions.
- Longitudinal organ dimensions correlated best with body height, followed by age, weight, and body surface area.
- Polynomial correlation was observed between height and organ dimensions.
Conclusions:
- Normal dimension ranges for pediatric liver, spleen, and kidney are defined.
- Body height is the most reliable anthropometric correlate for longitudinal organ dimensions in children.
- These findings support routine sonographic assessment and diagnosis in pediatric patients.
Objective:
The objective of this study was to determine the normal range of dimensions for the liver, spleen, and kidney in healthy neonates, infants, and children.
Subjects And Methods:
This prospective study involved 307 pediatric subjects (169 girls and 138 boys) with normal physical or sonographic findings who were examined because of problems unrelated to the measured organs. The subjects were 5 days to 16 years old. All measured organs were sonographically normal. At least two dimensions were obtained for each liver, spleen, and kidney. Relationships of the dimensions of these organs with sex, age, body weight, height, and body surface area were investigated. Suggested limits of normal dimensions were defined.
Results:
Dimensions of the measured organs were not statistically different in boys and girls. Longitudinal dimensions of all three organs showed the best correlation with age, body weight, height, and body surface area. Height showed the strongest correlation of all. This correlation was a polynomial correlation.
Conclusion:
Determination of pathologic changes in size of the liver, spleen, and kidney necessitates knowing the normal range of dimensions for these organs in healthy neonates, infants, and children. Presented data are applicable in daily routine sonography. Body height should be considered the best criteria to correlate with longitudinal dimensions of these organs.
