A method for synthesizing crossing ADC distributions via reassembly of multiple k-spaces is disclosed. The method includes the steps of scanning a test object having a plurality of anisotropic structures to acquire a first set of DTI data using gradient directions; rotating the gradient directions by an angle .alpha.; repeating the step of scanning the test object to acquire a second set of DTI data; creating a composite data set from the first and second sets of data; and applying an inverse Fourier transform to the composite data set.
