Conclusion: For DTI data with visible artifacts, a carefully constructed study‐specific template may achieve higher normalization accuracy than that of standardized templates. However, for data without visible artifacts, the study‐specific template and the standardized template of higher quality (IIT2) resulted in similar normalization accuracy. Results: It was demonstrated that, for DTI data with visible artifacts, the study‐specific template resulted in significantly higher spatial normalization accuracy than standardized templates. The accuracy of inter‐subject spatial normalization was compared across templates, using the most effective registration technique for each template and group of data. Materials and Methods: Two groups of diffusion tensor imaging (DTI) datasets, with and without visible artifacts, were normalized to two standardized diffusion tensor templates (IIT2, ICBM81) as well as study‐specific templates, using three registration approaches. Google has not performed a legal analysis and makes no representation as to the accuracy of the date listed. Purpose: To investigate the effect of standardized and study‐specific human brain diffusion tensor templates on the accuracy of spatial normalization, without ignoring the important roles of data quality and registration algorithm effectiveness. Priority date (The priority date is an assumption and is not a legal conclusion.
