Pediatric neuroimaging in pre-CT era: back to the future

Area of Science:

• Neurology
• Medical Imaging
• Pediatric Neurosurgery

Background:

• Neurological diagnosis historically relied on clinical evaluation and invasive procedures like cerebral angiography.
• The advent of computerized tomography (CT) and magnetic resonance (MR) imaging revolutionized diagnostic capabilities.
• Invasive tests are now rarely used in pediatric neurosurgery due to advanced non-invasive imaging.

Purpose of the Study:

• To review the historical development and advancements in pediatric neuroimaging techniques.
• To provide context on the diagnostic landscape prior to the CT era.
• To highlight the transition towards non-invasive neuroimaging modalities.

Main Methods:

• Literature review of diagnostic neuroimaging techniques.
• Analysis of historical trends in pediatric neurological assessment.
• Comparison of invasive versus non-invasive neuroimaging modalities.

Main Results:

• Pre-CT era neuroimaging included invasive tests such as angiography, encephalography, and myelography.
• Non-invasive methods like nuclear brain scans and ultrasonography emerged, with ultrasonography gaining prominence due to portability and safety.
• Ultrasonography is now a primary tool for neonatal evaluations.

Conclusions:

• Pediatric neuroimaging has significantly advanced over the past 50 years.
• The introduction of CT and MR marked a paradigm shift, reducing reliance on invasive procedures.
• Non-invasive techniques, particularly ultrasonography, are crucial in modern pediatric neuroimaging.
