To whom it may concern,

I use MITK-v2018.04.02-windows-x86_64
I encountered an error while loading DCE-MRI DICOM image.
This problem is in some case (loading 77 DCE-MRI images and 12 images had this problem)

I don't quite understand the meaning of the error message.
So I would like to ask how to solve such an error to successfully load the image.

I adopted the extended tofts model to estimate the features of BBB permeability.
Another problem is that I want to know the meaning of fit starting parameters (e.g. Ktrans Value: 15. Does it mean that the Ktrans value start from 15? However, Ktrans value is considered to be in the range of 10-4 to 10-3 min-1 )

The other problem is that I want to know the formula of relative signal enhancement and the meaning of conversion factor k (Conversion: Signal to Concentration)

Thank you !
