1. ABSTRACT
Phase II trial of bevacizumab for recurrent Calculation of the impulse response function, h(t): two methods
grade III-IV glioblastoma
Analytical solution Numerical deconvolution
(model based) (model independent)
h(t) calculated directly from
h(t) expressed as function
Postcontrast static T1 weighted
blood (Ca) & tissue (C t) curves
of model parameters
DCE-MRI image. Tumor
via matrix computation

Automation of numerical deconvolution analysis Numerical deconvolution results
Noncompartmental analysis of h(t)
Sensitivity of noncompartmental analysis to truncation
and lag-time correction of Ca and Ct
All h(t)’s shown h(t) >0 for all t
