Low-Field Magnetic Resonance Imaging of Canine Hydrocephalus

Abstract

The aim of presented study was to evaluate selected surface spine coil, and low-field magnetic resonance (MR) selected sequences in diagnosing hydrocephalus in dogs. This paper discusses 19 dogs (14 canine patients with hydrocephalus and 5 healthy dogs), of five breeds, subjected to low-field magnetic resonance imaging (MRI) of hydrocephalus. Area of the lateral ventricles and brain were examined in dogs with hydrocephalus using low-field MRI (at 0.25 Tesla). The MRI of FSE REL, SE, FLAIR, STIR, 3D HYCE, T3DT1, GE STIR 3D and 3D SHARC sequences with an indication of the most effective sequences are described. Additionally, coils for MR were compared, and models for infusion anesthesia were described. As a result of performed study all estimated sequences were diagnostically useful. However, spinal coil No. 2 (ESAOTE) was the most optimal for examining and positioning the cranium.
