Fig. 1From: Quantitative evaluation of activity of thyroid-associated Ophthalmopathy using short-tau inversion recovery (STIR) sequenceMeasurement of signal intensities of extraocular muscles on STIR imaging in one inactive eye (A) and one active eye (B). The signal intensity in each muscle was normalized to that in white matter of the same slice. Abbreviations: SR = superior rectus; IR = inferior rectus; LR = lateral rectus; MR = medial rectus.
