【摘要】：目的探讨利用透明质酸钠做全泪道成像的可行性。方法对27例(54侧)溢泪和(或)溢脓患者进行磁共振全泪道扫描。9例(18侧)泪道以生理盐水做对比剂为第1组,18例(36侧)泪道以透明质酸钠做对比剂为第2组,分别行三维快速恢复快速自旋回波序列扫描。以泪道内镜为金标准,评价三维快速恢复快速自旋回波序列对泪小管、泪囊和鼻泪管的显像情况。结果泪小管:1组中,能显示但信号较低2侧、无显示16侧;2组中,清晰显示35侧、能显示但信号较低1侧。泪囊:1组中,清晰显示13侧、能显示但信号较低5侧;2组中,清晰显示36侧。以内镜为金标准,1组方法诊断鼻泪管通畅度准确率为77.77%(14/18),2组方法诊断鼻泪管通畅度准确率为97.22%(35/36),差异有统计学意义(P0.05)。结论利用透明质酸钠行MR全泪道水成像能为眼科医生提供更详尽的信息,有利于提高手术的成功率。
[Abstract]:Objective to explore the feasibility of total lacrimal duct imaging using sodium hyaluronate. Methods 27 patients (54 sides) with lacrimal discharge and / or pus were examined with magnetic resonance imaging (MRI) of the lacrimal duct in 9 cases (18 sides) with normal saline as contrast medium. 18 cases (36 sides) of lacrimal duct were treated with sodium hyaluronate as contrast medium as the second group. Three-dimensional fast recovery fast spin echo sequence scanning was performed respectively. Using lacrimal duct endoscopy as the golden standard, the images of lacrimal tubules, lacrimal sac and nasolacrimal duct were evaluated. Results in the lacrimal canaliculus 1 group, the signal intensity was lower in 2 sides, while in the no 16 sides group, 35 sides could be clearly displayed, and 1 side could be displayed but the signal was lower. In group 1, 13 sides of lacrimal sac were clearly displayed, while 36 sides were clearly displayed in group 2 with low signal intensity (5 sides). The diagnostic accuracy of nasolacrimal duct patency was 77.77% (14 / 18) in group 1 and 97.22% (35 / 36) in group 2 (P0.05). Conclusion Mr total lacrimal duct imaging with sodium hyaluronate can provide more detailed information for ophthalmologists and improve the success rate of operation.
