![]() When combining the FA values of efferent 1 with disease duration, the present DTI tractography analysis could be useful for differentiating MSA-C and CCA patients. ![]() The present DTI tractography newly showed that the FA values of two afferent fiber tracts showed significant declines in MSA-C patients, and afferent 1 showed good diagnostic sensitivity and specificity. Linear regressions showed strong correlations between FA value and disease duration in CCA patients (efferent 1, r = -0.466 afferent 2, r = -0.543 both p<0.05), and between the FA value and the ratio of the standardized scale for the assessment and rating of ataxia (SARA)/disease duration in MSA-C patients (afferent 1, r = -0.407 p<0.01). MedINRIA es un software de procesamiento y visualización de imágenes médicas multi-plataforma. Receiver-operator characteristic curve analysis showed 85.7 % sensitivity and 75.0 % specificity of FA values in afferent 1 (cutoff value 0.476). medInria can be used for a wide variety of tasks. ![]() Compared with CCA, MSA-C patients showed significant declines of fractional anisotropy (FA) values of afferent 1 and 2 (p<0.01, respectively) and a significant increase of the radial diffusivity (RD) value in afferent 1 (p<0.05). Forty-one MSA-C patients (62.7 ± 8.1 years old, mean ± SD) and age- and gender-matched 15 CCA patients (63.0 ± 8.6 years old) were examined.Tractography was performed using the DTI track module provided in the MedINRIA version 1.9.4, and regions of interest were drawn manually to reconstruct an efferent fiber tract and two afferent fiber tracts via the cerebellum. In this tool targeting the clinicians, we. The objective of this study is to determine whether diffusion tensor imaging (DTI) tractography analysis is a potential method for differentiating cerebellar ataxia patients with multiple system atrophy with predominant cerebellar ataxia (MSA-C) and cortical cerebellar atrophy (CCA). We show how LE metrics are implemented into a software called MedINRIA, and more especially in a module named DTI Track dedicated to DT-MRI processing.
