In pediatric ultrasound, a “fontanelle window” refers to the soft spots on an infant’s skull where the cranial bones have not yet fused. These fibrous membranes provide crucial acoustic pathways for sonographic imaging of the brain. Utilizing the anterior fontanelle, in particular, allows medical professionals to visualize intracranial structures, detect abnormalities, and assess conditions like hydrocephalus or hemorrhage without the need for ionizing radiation.
This non-invasive approach is invaluable for neonatal and infant neurology. Pediatricians and sonographers rely on the fontanelle window for accurate, real-time diagnostic imaging, making it a cornerstone of medical ultrasound in the assessment of a child’s developing brain.
