Extraocular muscle sampled volume in Graves' orbitopathy using 3-T fast spin-echo MRI with iterative decomposition of water and fat sequences
Abstract
Background: 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.
Purpose: To measure the EOM sampled volume (SV) and assess its correlation with proptosis.
Material and Methods: A total of 37 patients with newly diagnosed GO underwent 3-T MRI scanning with iterative
