Extraocular muscle sampled volume in Graves’ orbitopathy using 3-T fast spin-echo MRI with iterative decomposition of water and fat sequences

Current magnetic resonance imaging (MRI) techniques for measuring extraocular muscle (EOM) volume enlargement are not ideally suited for routine follow-up of Graves’ ophthalmopathy (GO) because the difficulty of segmenting the muscles at the tendon insertion complicates and lengthens the study protocol
