WebNov 2, 2024 · Imperfect segmentation was obtained by segmenting MR images with SPM12. Bias and coefficient of variability (COV) were computed for quantitative comparison. Results indicated PVC methods with subtle use of MR guidance to show stronger resilience to imperfect MR information compared to methods with stronger assumptions invoked in … WebThe reference 3D-T2WI was acquired using the method used for 3D-T1WIs. Then, six 3D-T1WIs were processed using intrasubject bias-correction processing with SPM12, resulting in six new 3D-T1WIs of nonuniform signal intensities. Thirteen volume data sets were segmented into native-space tissue probability data using SPM12.
