Claim 0:
1. A method for producing parameter maps from magnetic resonance images obtained at a multitude of contrast-weighting levels, the steps comprising:
a) selecting predefined contrast-weighting levels;
b) performing at each image pixel position a higher-order function fit to the multitude of measured contrast-weighting level dependent signals at said pixel position;
c) determining for each said pixel position computed signal values from said higher-order function fit at said predefined contrast weighting levels;
d) performing at each said pixel position a monoexponential function fit through said computed signal values related to said pixel position at said predefined contrast weighting levels and determine a monoexponential decay parameter; and
e) assemble said monoexponential decay parameter of all image pixel positions to a parameter map for display.
