CAR/CanSPR Practice Guidelines: FAST MRI for Pediatric Neuroimaging
Year: 2026
Type: article
Abstract: Focused Abbreviated Survey Technique (FAST) MRI protocols address the clinical challenges of prolonged scan times, sedation requirements, and ionizing radiation exposure in pediatric neuroimaging. These guidelines, developed by the Canadian Society of Pediatric Radiology (CanSPR), provide evidence-informed recommendations to assist practitioners in the selective application of abbreviated MRI protocols across diverse clinical scenarios. Based on comprehensive literature review and expert consensus, the working group established a framework for using FAST MRI as a targeted, CT-sparing strategy. The guideline outlines protocols and indications for the follow-up of hydrocephalus, arachnoid cysts, and syringomyelia. It also addresses its application in acute settings, including suspected stroke, first-time seizures, and accidental trauma, as well as its role in evaluating macrocrania following inconclusive ultrasound and headaches. While FAST MRI facilitates timely diagnosis and improves safety by minimizing anesthesia, it may have lower spatial resolution than conventional protocols. Consequently, these recommendations emphasize its use for targeted diagnostic questions rather than as a replacement for comprehensive MRI examinations.
