SUSCEPTIBILITY ARTIFACTS ON T2*-WEIGHTED MAGNETIC RESONANCE IMAGING OF THE CANINE AND FELINE SPINE

摘要: The T2*-weighted gradient recalled echo sequence is a sensitive means to detect blood degradation products. While not routine in magnetic resonance imaging of the spine small animals, it can provide additional valuable information select cases. goal this retrospective, cross-sectional study was describe findings when acquiring during examination animals. University Tennessee's veterinary radiology database searched for dogs and cats that underwent suspect spinal disease which acquired susceptibility artifact identified. following recorded: signalment, clinical signs, location appearance artifact, final diagnosis. Thirty-nine cases were included study. Extradural artifacts observed intervertebral disc herniation with or without associated hemorrhage (n = 28), extradural trauma 2), hemophilia 1), cystic mass 1). Remaining lesions displaying intramedullary presumptive acute noncompressive nucleus pulposus extrusion hematoma hemangiosarcoma metastasis meningomyelitis undetermined etiology Inclusion may be helpful standard sequences are ambiguous observed.
