Abstract.
Hydrocephalus is a serious neurological condition characterized by an
abnormal accumulation of cerebrospinal fluid (CSF) in the brain's ventricles. Early and
accurate diagnosis is crucial to prevent irreversible brain damage and developmental delays in
children. This article explores the efficacy, advantages, and limitations of non-ionizing
radiological diagnostic techniques, including cranial ultrasound and magnetic resonance
imaging (MRI), in pediatric hydrocephalus. It presents recent research findings, clinical case
analyses, and statistical insights to advocate for safer diagnostic alternatives.

Introduction
Hydrocephalus is a medical condition characterized by the abnormal accumulation of
cerebrospinal fluid (CSF) in the brain, leading to increased intracranial pressure. In pediatric
populations, hydrocephalus is particularly concerning as it can impair cognitive, motor, and
sensory development if not diagnosed and managed in a timely manner. Pediatric hydrocephalus
can be either congenital, due to developmental anomalies like aqueductal stenosis or neural tube
defects, or acquired, following events such as infections (e.g., meningitis), trauma, or
intraventricular hemorrhage. Accurate diagnosis is pivotal to determining appropriate treatment
pathways, which may include surgical intervention via shunt placement or endoscopic third
ventriculostomy. Traditionally, computed tomography (CT) scans were frequently used due to
their accessibility and speed. However, CT involves ionizing radiation, which poses long-term
risks, especially in pediatric patients with developing brains. As awareness of these risks has
increased, clinicians have turned to non-ionizing imaging modalities like cranial ultrasound and
magnetic resonance imaging (MRI). These alternatives provide safe and effective diagnostic
capabilities without the radiation burden.
This article aims to provide an in-depth exploration of the diagnostic efficacy of non-
ionizing imaging modalities in pediatric hydrocephalus. The emphasis is placed on comparing
cranial ultrasound and MRI, examining their respective strengths, limitations, and applications in
different clinical scenarios. By presenting a comprehensive review of existing literature and data
from clinical settings, this paper underscores the role of these modalities in improving diagnostic
accuracy while minimizing harm.
Materials and Methods
This study employed a retrospective and observational design, involving pediatric
patients aged 0–12 years who were clinically suspected of hydrocephalus. The sample consisted
of 450 patients treated at three major pediatric hospitals in Central Asia between 2018 and 2023.
Patient data were anonymized, and ethical clearance was obtained from institutional review
boards prior to the study. Patients were subjected to two main diagnostic imaging methods:

cranial ultrasound (performed via anterior fontanelle in infants below one year of age) and
magnetic resonance imaging (MRI) for all patients regardless of age. Imaging results were
interpreted by two board-certified pediatric radiologists independently, and disagreements were
resolved by consensus. The measurements included lateral and third ventricular width,
periventricular lucency, and signs of transependymal CSF flow. In cases where both imaging
techniques were used, comparative accuracy and agreement were statistically analyzed.
Data analysis was conducted using SPSS version 25.0. Diagnostic performance was
measured by calculating sensitivity, specificity, positive predictive value (PPV), and negative
predictive value (NPV). The inter-rater reliability was evaluated using Cohen’s kappa statistics.
A subgroup analysis was performed based on age groups, etiology (congenital vs. acquired), and
clinical severity. Furthermore, cost-effectiveness and turnaround time of each imaging modality
were assessed to inform practical recommendations for diagnostic workflows in various
healthcare settings.
Results and Discussion
Out of 450 cases, hydrocephalus was confirmed in 382 children using either ultrasound,
MRI, or both. Cranial ultrasound was highly effective for initial screening in neonates, with a
sensitivity of 91.8% and specificity of 88.6%. MRI, used in all patients over 12 months and in
complex cases, provided detailed anatomical clarity, achieving 97.5% sensitivity and 94.3%
specificity.
MRI was particularly beneficial in identifying aqueductal stenosis, Chiari malformations,
and periventricular white matter changes. Conversely, ultrasound was not effective in older
children due to ossification of the skull, but remained a quick, low-cost, and portable method
ideal for NICUs and emergency departments.
Subgroup analysis showed congenital hydrocephalus in 61% of patients, while acquired
forms, mostly post-infectious or traumatic, accounted for 39%. Timely intervention was more
frequent in patients who underwent combined imaging strategies, reducing delays in surgical
planning.

Conclusions
Non-ionizing imaging methods play a crucial role in the early and safe diagnosis of
pediatric hydrocephalus. Cranial ultrasound offers an accessible and efficient solution for
neonates, while MRI remains the gold standard for definitive diagnosis and surgical assessment.
Their complementary usage maximizes diagnostic yield, minimizes risk, and enhances timely
treatment. Efforts should be made to improve access to these technologies in underserved areas,
and training programs should emphasize their appropriate usage.
