SNR and mean contrast-to-noise ratio were better on 3T compared with 1.5T (<em>P</em> ≤ .05). The goodness of fit of the Tofts and Tofts extended pharmacokinetic models was similar between 1.5T and 3T. Thus, dynamic contrast-enhanced MR perfusion of intradural spinal canal lesions is technically feasible at 1.5T and 3T, with better image quality at 3T.</p></div></div><div class="section glossary" id="glossary-1"><h2 class="">ABBREVIATIONS:</h2><dl id="def-list-1"><dt id="def-item-1">AUC<span class="def-item-dt-sep"></span></dt><dd>area under the curve<span class="def-item-dd-sep"></span></dd><dt id="def-item-2">CNR<span class="def-item-dt-sep"></span></dt><dd>contrast-to-noise ratio<span class="def-item-dd-sep"></span></dd><dt id="def-item-3">DCE<span class="def-item-dt-sep"></span></dt><dd>dynamic contrast-enhanced<span class="def-item-dd-sep"></span></dd><dt id="def-item-4"><em>K</em><sup>trans</sup><span class="def-item-dt-sep"></span></dt><dd>volume transfer constant<span class="def-item-dd-sep"></span></dd><dt id="def-item-5"><em>v</em><sub>e</sub><span class="def-item-dt-sep"></span></dt><dd>extravascular extracellular volume fraction<span class="def-item-dd-sep"></span></dd><dt id="def-item-6"><em>v</em><sub>p</sub><span class="def-item-dt-sep"></span></dt><dd>blood plasma fraction</dd></dl></div><ul class="copyright-statement"><li class="fn" id="copyright-statement-1">© 2017 by American Journal of Neuroradiology</li></ul><span class="highwire-journal-article-marker-end"></span></div><span class="related-urls"></span></div><a href="http://ajnr-stage2.stage.highwire.org/content/38/1/192.full" class="hw-link hw-link-article-full-text" data-icon-position="" data-hide-link-title="0">View Full Text</a></div>  </div>
