摘　　要：目的观察糖尿病视网膜病变（DR）患者眼动脉磁共振血管造影（MRA）影像特征。方法临床检查确诊的DR患者36例72只眼（DR组）纳入研究。其中，男性21例42只眼；女性15例30只眼。平均年龄55.2岁。平均糖尿病病程7.56年。均行眼动脉MRA、荧光素眼底血管造影（FFA）检查；同时行眼动脉CT血管造影（CTA）检查12例24只眼。选取同期年龄、性别匹配的健康志愿者22名作为对照组。其中，男性 13名，女性9名。均行眼动脉MRA检查；同时行眼动脉CTA检查5名10只眼。根据眼动脉显影状况和外形改变将MRA、CTA分为0级：无异常；Ⅰ级：轻度病变；Ⅱ级：明显病变。根据FFA检查结果，分为无明显病变期；背景期；增生前期；增生期。对比观察DR组、对照组受检者眼动脉MRA形态特征；DR组患者眼动脉MRA分级与FFA分期之间的关系。DR组患者眼动脉MRA、CTA分级之间的一致性分析采用Kappa检验；眼动脉MRA分级与FFA分期之间的关系采用双向有序属性相同资料的Spearson相关分析。结果对照组44只眼中，眼动脉MRA 0、Ⅰ级分别为41、3只眼。行眼动脉CTA检查的10只眼均为0级。DR组72只眼中，眼动脉MRA 0、Ⅰ、Ⅱ级分别为28、28、16只眼。行CTA检查的24只眼中，0、Ⅰ、Ⅱ级分别为13、6、5只眼。DR组眼动脉MRA、CTA分级一致性分析，Kappa值=0.86，具有高度一致性。DR组、对照组眼动脉MRA不同分级眼数比较，差异有统计学意义（Z=？5.74，P=0.000）。DR组72只眼中，FFA分期无明显病变期、背景期、增生前期、增生期分别为8、12、22、30只眼。 相关性分析结果显示，DR组眼动脉MRA分级与FFA分期呈显著相关性（r=0.405，P=0.000）。结论MRA可显示眼动脉形态变化，并在一定程度上反映DR分期；与FFA血管改变有较高的一致性。ObjectiveTo observe the characteristics of magnetic resonance angiography of （MRA） ophthalmic artery in patients with diabetic retinopathy （DR）.MethodsA total of 36 eyes of DR patients （DR group） diagnosed by clinical examination were included in the study. Among them, there were 42 eyes in 21 males and 15 eyes in 15 females. The average age was 55.2 years old. The average duration of diabetes was 7.56 years. All eyes were examined by MRA and fluorescein fundus angiography （FFA） in the ophthalmic artery. At the same time, 24 eyes of 12 patients were examined by computed tomography angiography （CTA）. Twenty-two healthy volunteers with age and gender matching were selected as the control group. Among them, there were 13 males and 9 females. All patients underwent MRA examination of the ophthalmic artery; at the same time, 5 eyes of 5 eyes were examined by CTA. MRA and CTA were classified into three grades according to the development condition and shape change of the ophthalmic artery. 0 grade ： no abnormality; grade Ⅰ： mild lesion; grade Ⅱ： obvious lesion. According to the results of FFA examination, it was divided into no obvious disease stage, background stage, proliferative stage, proliferative stage. The morphological features of the MRA of the ophthalmic artery in the DR group and the control group were compared. The relationship between the MRA grading of the ophthalmic artery and the FFA staging was observed in the DR group. The consistency analysis between the MRA and CTA grades of the ophthalmic artery in the DR group was performed by Kappa test; the relationship between the MRA grade and the FFA staging of the ophthalmic artery was analyzed by Spearson correlation analysis of the same data with two-way ordered attributes.ResultsIn 44 eyes of the control group, the MRA in grade 0 and Ⅰ of the ophthalmic artery were 41 and 3 eyes, respectively; all eyes of the CTA examination of the ophthalmic artery were grade 0. In 72 eyes of the DR group, the MRA in grade 0, Ⅰ, and Ⅱ
