Abstract

Background: A number of metaphorical imaging signs have been described in the radiology literature.

Objective: These signs not only make the learning process easier but also increase diagnostic confidence. For this reason, these signs are quite popular among radiologists.

Conclusion: In this article, we have demonstrated classic signs described in pediatric neuroradiology with appropriate examples and illustrations.

Keywords: Pediatric, neuroradiology, CT, MRI, HRCT, pediatric neuroimaging.
