In paediatric neuroimaging, young children have often to be sedated in order to obtain diagnostic MRI images. Magnetic Resonance Fingerprinting (MRF) is a potential alternative to sedation in children, as it achieves a fast exam with reduced sensitivity to patient motion. MRF acquisitions can be used to acquire a fully-quantitative anatomical exam in less than five minutes at a standard resolution. We performed a preliminary evaluation of MRF in 15 paediatric patients, acquiring both the standard protocol and MRF at 1.5T. Detection of brain alterations was possible, if present, in all patients. Only a few small lesions were unrevealed. MRF could be a promising tool for a fast and diagnostic exam in children, and due to its low sensitivity to motion it has the potential to allow exams without sedation.
