Abstract
Objective To evaluate the value of diffusion registration in diffusion tensor imaging (DTI) through comparing the diffusion tensor data to conduct the two kinds of post-processing methods for obtaining the ADC ,eADC and FA values and the vis-ual neural fiber length .Methods 20 cases of DTI data were analyzed retrospectively .The original data were adopted to directly process for obtaining the ADC ,eADC and FA values respectively ,after exerting diffusion registration the ADC ,eADC and FA val-ues were measured again ,at the same time the two different processing modes were performed the fiber trace imaging ,.The changes of ADC ,eADC and FA values in each case were compared before and after exerting the diffusion registration ,and at the same time the differences of fiber length in the same interest area in the fiber trace image were compared before and after exerting the diffusion registration .Results The difference of the ADC and eADC values obtained before and after exerting the diffusion registration in the normal group showed no statistical significance (P=0 .695 3 ,P=0 .632 1) and the FA value difference between before and after ex-erting the diffusion registration had statistical significance (P=0 .032 1);the difference of the ADC and eADC values obtained be-fore and after exerting the diffusion registration in the clinical patients group had no statistical significance ( P= 0 .203 9 ,P=0 .075 4) ,the FA value difference had statistical significance (P=0 .011 4) ,the visual neural fiber length was elongated after exer-ting the diffusion registration .Conclusion The diffusion registration processing can obtain better quality of ADC ,eADC ,FA images and the fiber trace image ,more reliable ADC ,eADC and FA values ,the visual fiber length is elongated ,which has large application value in MR DTI .关键词
