Reply: ====== * S. Karimi I appreciate the comments in the letter to the Editor and the interest in our publication. The parameters used in our project best fit our dynamic contrast-enhanced (DCE) model with the FDA-approved software. I find the comments interesting and truly hope that the commentators use their suggestions on their own spine DCE data, and I look forward to their publications in this area along with a discussion of histopathology of hemangiomas. * © 2018 by American Journal of Neuroradiology
