Unfortunately, this sort of volumetric analysis would very likely add little in terms of providing objective guidance about re-treating a given aneurysm, as the authors of the letter acknowledge. The use of volumetric analysis might have some value in the context of a clinical trial but very likely would offer scant benefit to clinical practice. We do, however, applaud any attempt to provide improved analytic tools to the aneurysm-research community and wish Dr Groth and colleagues success in their chosen line of investigation.</p><ul class="copyright-statement"><li class="fn" id="copyright-statement-1">© 2011 by American Journal of Neuroradiology</li></ul><span class="highwire-journal-article-marker-end"></span></div><span class="related-urls"></span></div></div>  </div>
