For in-line calculation of cerebral haemodynamic parameter images the maximum slope method was assessed by a simulation study and in comparison with deconvolution techniques for clinical data. Additionally the lag-time of a correlation analysis between a local voxel and the global bolus was considers as analogue to the mean transit time. With advanced methods for data preprocessing the maximum slope method performed equally well as deconvolution techniques. The lag times was found to be even more robust than the MTT calculated from the normalized residue function.
