The patients with strabismus, including 8 with superior oblique paresis, 1 with inferior rectus paresis, and 1 with congenital constant exotropia, were examined with MR imaging at 1.5 tesla (T) or 0.5T with a surface coil. Abnormal findings of extraocular muscles were identified in 8 of the 10 patients and most of them were consistent with the clinical findings. Deviation of the optic nerves was noted in 5 patients. Coronal short repetition time (RT) and echo time (ET) images were used to measure the concerned extraocular muscles and the optic nerves. The differences in diameters between the concerned extraocular muscles of both the diseased and normal eyes were calculated. MR imaging is considered to be advantageous and can be favorably used to observe and measure the extraocular muscles and other intraorbital structures in patients with strabismus.
斜视患者，包括8例上斜肌麻痹、1例下直肌麻痹和1例先天性恒定性外斜视患者，使用1.5特斯拉（T）或0.5T的磁共振成像（MR）及表面线圈进行检查。10例患者中有8例发现眼外肌异常，且大多数与临床检查结果相符。5例患者出现视神经偏移。采用冠状面短重复时间（RT）和回波时间（ET）图像测量相关眼外肌和视神经。计算患眼和健眼相关眼外肌直径的差异。MR成像被认为具有优势，可有效用于观察和测量斜视患者的眼外肌及其他眶内结构。
