MRI DIFFUSION WEIGHTED IMAGING WITH ESTIMATED MOTION PROBING GRADIENT b-FACTORS BASED ON ACQUIRED APPARENT DIFFUSION COEFFICIENTS FOR EACH PIXEL

A magnetic resonance diagnostic apparatus comprising:

• an imaging unit to obtain at least two original images by imaging an imaging region on a subject using at least two b-factors, respectively;
• a derivation unit to derive an apparent diffusion coefficient regarding a pixel position for each pixel position included in a region of interest in the at least two original images, based on pixel values of each of the at least two original images regarding the pixel positions;
• and
• an estimation unit to estimate a pixel value obtained by using a b-factor which is different from the at least two b-factors, regarding each pixel position included in the region of interest, based on the apparent diffusion coefficient derived for each pixel position;
• wherein the at least two b-factors are set in accordance with a portion a the subject included in the imaging region.
