Abstract

One of the most significant impacts of magnetic resonance (MRI) has been its ability to exquisitely depict normal and pathologic anatomy of the spine. This unit presents a that deals with intramedullary disease, i.e., that involving the cord. An is presented for cases of extramedullaryÔÇÉintradural disease.

Materials

Basic Protocol 1: Myelopathy

  Materials
  • Normal saline (0.9% NaCl; 500‐ml bag)
  • K‐50 tubing
  • 23‐ to 25‐G butterfly needle
  • Intravenous MRI contrast agent (e.g., Magnevist, Omniscan, Prohance, or OptiMark at a dose of 0.1 mmol/kg for high field or 0.2 mmol/kg for low field).
NOTE: Be sure that technicians and nurses always have immediate access to any emergency equipment that may be relevant to a given study, or that may be needed for a particular patient—i.e., crash carts and oxygen.
