title: Usefulness of intraoperative ultrasonography for two dogs with spinal disease.
abstract: Intraoperative ultrasonography was performed during spinal surgery in two dogs. An extradural lesion was demonstrated by myelography in case 1, and an extradural tumor was found during surgery. Case 2 was diagnosed with a spinal subarachnoid cyst by myelography and magnetic resonance imaging. Ultrasonographically, pathologic conditions of the spinal canal or cord were adequately imaged during surgery in both cases. Intraoperative ultrasonography was a superior method that non-invasively revealed intradural and extradural conditions and thus constitutes a valuable diagnostic mean to ensure safe and precise spinal surgery.
