DTI can be used to diagnose TAO with FA and radial diffusivity change in EOM. Diffusivities can be used to differentiate acute and chronic stage of TAO. However, DTI values showed limitation in reflecting TAO activity according to the CAS.

2023年8月22日 · DTI represents a feasible technique to assess tissue characteristics of EOM. The effects of eye position changes on DTI parameters are subtle. Decreased MD and RD could be evidence for remodeling of the medial rectus muscle contracture.

2024年12月24日 · To evaluate the utility of apparent diffusion coefficient (ADC) values of extraocular muscles (EOMs) in differentiating activity of thyroid eye disease (TED). Forty-two TED patients who underwent diffusion tensor imaging (DTI) were retrospectively enrolled in this study, including 29 patients in analysis group and 13 patients in validation group.

Introduction To investigate the extraocular muscle (EOM) changes in thyroid-associated orbitopathy (TAO) on DTI and the correlations between DTI parameters and clinical

2016年11月14日 · DTI can be used to diagnose TAO with FA and radial diffusivity change in EOM. Diffusivities can be used to differentiate acute and chronic stage of TAO. However, DTI values showed limitation in reflecting TAO activity according to the CAS.

DTI values compared between patients in active and inactive phases by clinical activity score of TAO. DTI values were also compared between acute and chronic stages by the duration of disease. Results: In medial EOM, FA was significantly lower in patients (p < 0.001) and negatively correlated with muscle thickness (r = −0.604, p < 0.001).

2024年12月24日 · Our results showed that DTI is a valuable tool in the assessment of disease activity of TED. Both ADCmean of IR and ADC of all four EOMs can be used in discriminating disease activity with the same predictive power.

DTI values compared between patients in active and inactive phases by clinical activity score of TAO. DTI values were also compared between acute and chronic stages by the duration of disease. Results. In medial EOM, FA was significantly lower in patients (p < 0.001) and negatively correlated with muscle thickness (r = −0.604, p < 0.001).

2016年11月14日 · The correlation of the DTI values of EOM for muscle thickness and exophthalmos on CT in TAO patients were assessed by Spearman correlation. Differences in DTI values of the medial and lateral EOM were compared between patients in active and inactive phases, which were determined according to CAS score.

To evaluate the feasibility of diffusion tensor imaging (DTI) for the medial and lateral rectus extraocular muscle (EOM) evaluation, to investigate the normal DTI parameters of the medial and lateral rectus EOM, and to compare with other skeletal muscle.
