Does Magnetic Resonance Brain Scanning at 3.0 Tesla Pose a Hyperthermic Challenge to Term Neonates?

J Pediatr. 2016 Aug:175:228-230.e1. doi: 10.1016/j.jpeds.2016.05.014. Epub 2016 Jun 15.

Abstract

Next-generation 3-Tesla magnetic resonance (MR) scanners offer improved neonatal neuroimaging, but the greater associated radiofrequency radiation may increase the risk of hyperthermia. Safety data for neonatal 3-T MR scanning are lacking. We measured rectal temperatures continuously in 25 neonates undergoing 3-T brain MR imaging and observed no significant hyperthermic threat.

Keywords: neuroimaging; nonionizing radiation; radiofrequency radiation; specific absorption rate.
