Gadolinium-Enhanced MRI and Positron Emission Tomography in Bell’s palsy: A Preliminary Report
An inflammatory edema with secondary ischemia of the facial nerve may be the cause of Bell’s palsy [1, 5]. This may accord with the transient facial nerve enhancement on gadolinium-enhanced magnetic resonance imaging (GadMRI) that we recently have reported . In this previous study  we used carbohydrate and gadolinium in an attempt to improve the GadMRI technique. The aim of the present preliminary study was to see if readministration of gadolinium may give additional information when examining patients with Bell’s palsy on high-Tesla MR equipment. Furthermore, we report our limited experience from three investigations using positron emission tomography (PET), a unique imaging technique which allows in vivo measurements of the anatomical distribution and rates of specific biochemical reactions .
