Figure 2

T2 value histogram analysis of a 63-year old TAO patient (a–c) and a sex and age-matched healthy control subject (d–f). The top figure (a–c) were from a 63-year old TAO patient; the bottom figure (d–f) were from a sex and age-matched healthy control subject. (a) The colorful ROI on the left represents the involved left medial rectus (MR), and the colorful ROI on the right stands for the normal-appearing right MR. (b) The histogram T2 parameters of involved left MR. (c) The histogram T2 parameters of right normal appearing MR. (d) The colorful ROI represents the left and right MR of a sex and age-matched healthy control subjects. (e,f) The histogram parameters of left MR and right MR in the healthy control. Note: due to the chemical shift phenomena between muscle and fat, the signal of the marginal muscles were not the true signal of muscle, therefore, we excluded this part out of the ROI to ensure the measurement accuracy.
