The invention discloses a newborn brain development quantitative analysis method based on a magnetic resonance diffusion tensor brain image. The method comprises the following steps: A, preprocessinga newborn DTI image, which includes data format conversion, image correction and brain tissue extraction; B, carrying out dispersion tensor parameter calculation; c, registering the FA image to an MNIstandard space and calculating an average FA image of the FA image; d, performing symmetry processing on the average FA image; e, extracting an FA skeleton from the average FA image subjected to thesymmetric processing; f, projecting each tested FA image into a symmetrical FA skeleton to obtain each tested FA skeleton diagram; and G, subtracting the FA values of the homologous isobaric voxels ofthe left brain and the right brain to obtain an absolute value of a difference value. By the adoption of the method, quantitative calculation is conducted on the brain white matter asymmetry index based on the DTI image, so that quantitative analysis on the brain development condition of the newborn is achieved.
