3T MRI in pediatrics

May 17, 2011

3T MRI is being increasingly performed for clinical purposes. The increased SNR is a significant advantage in pediatrics – improved spatial and temporal resolution assist in overcoming the major anatomic, physiologic and behavioural challenges of imaging children. 3T MRI has the potential to image all the systems in pediatrics. However, optimising the parameters with due consideration to specific pediatric features, such as the increased water content of non myelinated brain, is essential. The neonatal brain and pediatric spine are difficult to image at 3T. Several factors also limit cardiac imaging at present. Further improvements in coil technology and newer sequences may help overcome the challenges that remain. On the other hand, some 3T artefacts inherent to specific anatomic regions, like the dielectric effects encountered in adult abdominal imaging, are less problematic in pediatrics due the smaller size.
