Frontal ventricular dimensions of the brain in infants and children
Insights
The biventricular (V/H) index, measuring brain ventricular dimensions in children, shows a consistent Gaussian distribution from birth to 15 years. Unlike adults, this index does not change with age in pediatric patients.
Area of Science:
- Pediatric Radiology
- Neuroimaging
- Child Neurology
Background:
- Accurate assessment of ventricular dimensions is crucial in pediatric neuroimaging.
- The biventricular (V/H) index is a standardized method for evaluating ventricular size.
- Understanding age-related changes in pediatric brain anatomy is essential for diagnosing neurological conditions.
Purpose of the Study:
- To establish normative data for the biventricular (V/H) index in a pediatric population.
- To determine if the biventricular (V/H) index changes with age in children from birth to 15 years.
- To compare pediatric ventricular dimensions with known adult patterns.
Main Methods:
- Retrospective review of 400 computerized tomographic (CT) scans of pediatric brains (birth to 15 years).
- Calculation of the biventricular (V/H) index, defined as the ratio of caudate nuclei distance (V) to cerebral hemisphere width (H).
- Statistical analysis to determine the distribution and age-related trends of the V/H index.
Main Results:
- 142 out of 400 scans (35.5%) demonstrated normal ventricular dimensions based on the V/H index.
- The V/H index in the pediatric cohort followed a Gaussian distribution with a mean of 0.11 ± 0.03 and a range of 0.00 to 0.20.
- No significant increase in the V/H index was observed with advancing age in the pediatric population (0-15 years).
Conclusions:
- The biventricular (V/H) index provides a reliable measure for assessing normal ventricular dimensions in children.
- Pediatric ventricular dimensions, as assessed by the V/H index, remain stable throughout childhood and adolescence.
- These findings establish age-independent normative values for the V/H index in pediatric neuroimaging, differentiating it from adult patterns.
Abstract:
Four hundred computerized tomographic scans of the brain in infants and children from birth to 15 years of age were reviewed. Of these, 142 were judged to exhibit normal ventricular dimensions as determined by the biventricular (V/H) index, the length of a line drawn between the heads of the caudate nuclei (V) relative to the width of the cerebral hemispheres (H) at the same level. When all scans were analyzed collectively, the V/H index followed a Gaussian distribution (mean, .11 +/- .03) [SD]; range, .00 to .20). The index did not increase with advancing age within the pediatric population (0 to 15 years), as it does in adults.
