摘　　要：目的研究眼眶滑车钙化的MSCT表现及临床价值。方法收集因外伤或怀疑眼眶内异物来本院就诊并行眼眶MSCT检查的216例病例资料,并对其中检出的共计54例眼眶滑车钙化的MSCT表现进行分析。结果 216例患者中,检出的眼眶滑车钙化几率为25%(54/216),54例眼眶滑车钙化者的平均年龄为37.6岁。眼眶滑车钙化均位于眼眶内上壁旁,并与上斜肌折反肌腱相延续,眼眶滑车钙化形态不一,多为小斑点状或短条状,分布以双侧者多见(30/54),钙化平均CT值为165HU。结论眼眶滑车钙化的MSCT表现有特征性,正确认识其表现具有重要的临床实用价值。Objective To investigate the appearances and the clinical value of multi- slice CT（MSCT） in orbital trochlea calcification. Methods In this research, 216 patients with orbital MSCT examination due to trauma or suspected orbital foreign body were collected, in which 54 cases were detected with orbital trochlea calcification. The MSCT findings of 54 cases of orbital trochlea calcification were analysed.Results The 54 cases of orbital trochlea calcification accounted for 25 % of all patients （54/216） and the average age of them was 37.6 years.Orbital trochlea calcification was located in fixed position, attached to the top of the front medial orbital wall, continuous with the superior oblique tendon. bilateral calcification was showed in 30 cases. Major shape of the calcification was small spots or short strip. Size and shape of orbital trochlea calcification migbt be inconsistent with bilateral. The average CT value of calcification was 165HU. Conclusion MSCT can show the features of the orbital trochlea calcification and has an important clinical significance.
