AB SUMMARY: Fifteen patients with intradural spinal lesions were examined with an optimized dynamic contrast-enhanced MR perfusion sequence at 1.5T and 3T. SNR and mean contrast-to-noise ratio were better on 3T compared with 1.5T (P ≤ .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.AbbreviationsAUCarea under the curveCNRcontrast-to-noise ratioDCEdynamic contrast-enhancedKtransvolume transfer constantveextravascular extracellular volume fractionvpblood plasma fraction
