摘　　要：目的探讨MR泪道造影（MRD）技术和应用价值。方法20例正常人和8例慢性泪囊炎（CD）患者共53侧泪道接受了MRD检查，扫描序列为三维稳态构成干扰序列（3DCISS）和快速自旋回波（TSE）。统计MRD的显影结果，并对MRD图像进行分析。结果3DCISS序列MRD，40侧正常泪道显影22侧，13侧CD泪道显影11侧。3DCISS序列MRD较好地显示了正常人和CD患者泪道形态。TSE序列MRD对泪道的显示不如3DCISS序列，但是脂肪干扰少。结论MRD是一项可行的，具有独特价值的泪道检查方法。Objective To investigate the technique and application of MR dacryocystography (MRD).Methods Twenty normal persons and 8 patients with chronic dacryocystitis (CD) (53 lacrimal ducts in total)underwent MRD examination with 3D CISS and TSE sequences. Statistic results were obtained and MRD images were analyzed. Results 22 cases of 40 normal lacrimal passages and 11 cases of 13 CD lacrimal pessages were showed by MRD with 3D CISS sequence, Which delineated well the shape of lacrimal ducts in normal persons and CD patients. 3D CISS sequence was superior to TSE sequence in demonstrating lacrimal ducts. MRD with TSE sequence had less fat interference. Conclusion MRD is a feasible method in evaluating lacrimal passages.
